Selection Widget Updated Version

MarkHoyland

The Selection widget has a "Select by Attributes" and "Select by Location" option similar to ArcGIS.
Widget link: http://www.arcgis.com/home/item.html?id=20ed6af9ab204548bbf092d51b51fef8

Version 1.5 of the widget replaces version 1.0

Enhancements and fixes include:
*Each time a query layer was added it was also being added to the TOC. This has been fixed.

*When resizing the widget, the datgrid would not resize properly. This has been fixed.

*Uses paging for selection of unique value list. This means that ALL values will be parsed regardless of the ArcGISServer setting to limit responses. There is an option to ESC out of a large query. (This is only for the Unique list, not getting features).
I have included an ESRI TaxParcel Layer that has 18,000+ records. Get Unique Values on the PSTLSTATE field to see this in action.
Available on my example site. The URL is on the Widget download page.

*Aliases can now be used. It will now use the Alias as set in the Featureclass. You can also override the Alias in the SelectionWidget.xml config file.

*ArcGis layers that have joined tables will now work with fully qualified field names. (thanks Dasa for the idea)

*Styling for selection colours has been documented in the SelectionWidget.xml config file (example provided).

*Styling for datagrid has been changed. It can now also be styled in SelectionWidget.xml config file (example provided). (thanks Mehul for the idea)

*Changed initial uniquevalue query to use "text='%'" instead of "where '1=1'" for Mike.:)

*You can now override scale range for layers.

*Link field now has a prefix/suffix option in the SelectionWidget.xml config file (naming convention the same as Robert SCheitlin's esearch widget)

*Shape_area and Shape_length can be used in the fields.

Good Morning,

When compiling the widget, I get the following warnings:

In SelectByAttributes.mxml at lines 317 & 318 "Data binding will not be able to detect assignments to "length"."

In SelectionResults.mxml at lines 313, 318 & 323 "Data binding will not be able to detect assignments to "length"."

Also, is there a way to select what fields are displayed on the popup window when you hover over the selection? In the infowindow I need to see the data for all the fields but not in the popup window.

I am on Server 10, SP3, Viewer 2.4

Thanks and a great app.

Nestor.

To fix the issue with the date being represented by it's UTC decimal equivalent (I think), make the following changes on the SelectionResults.mxml file under components

add-> import mx.formatters.DateFormatter;

add ->

private function dateLabel(fullfieldname:String):Function {
    return  function (item:Object, column:DataGridColumn):String { 
     
     var dateFormatter:DateFormatter  = new DateFormatter ();
     dateFormatter.formatString = "MM/DD/YYYY";
     
     return dateFormatter.format(new Date(item[fullfieldname]));
    };
   }

modify->dgColumn.labelFunction = labelOf(fld.name);

change to -> dgColumn.labelFunction = fld.type == "esriFieldTypeDate" ? dateLabel(fld.name) : labelOf(fld.name);

you may want to have the formatter as a resource rather than create it in the function, either way this should fix that issue. Let me know if there are further refinements to this fix

Hello,

Thank you very much for this widget! I love the flexibility it provides. However, I am experiencing a couple problems. When I setup the widget, at first it looks great when I run a query, and when I hover over the data grid with all graphics in view, the info windows work as expected. As soon as I click on a row in the data grid, it zooms into that feature, as expected. However, whenever I hover over another item in the data grid, the popup for the feature I just zoomed to gets updated with the data from the feature I am hovering over. A similar thing happens when I click on a row at the bottom of the data grid. The map zooms to that feature, but the grid resets itself so the first records is displayed (ie-scrolls back to the top), but now my mouse is hovering over a different feature than I just clicked on, so the info window displays data from the feature I'm hovering over and not the one I just clicked on.

Any thoughts? I'm using ArcGIS 10.0 SP3 and FV 2.4.

Thanks,
Alan

I am having a devil of a time to get this widget to work. There is a spinning clock that spins to infinity and no values are coming in. This widget is exactly what we need. I am running Flash Builder 4.5 and Flex Viewer 2.4. Any help would be appreciated.

Hi Mark I am after some advice I have listed my layers in alphabetical order within the SelectionWidget.xml file however they don't always appear listed in alphabetical order in the viewer (FlexViewer 2.3). Do you have any idea how I would resolve this? How should I sequence the layers in the widget? Any information would be much appreciated.

Hi,

Is that got someone already recompiled the Selection Widget to flex viewer 2.4?

Hi Harold,

Thanks for this - it works great in the results data grid - can you suggest where the similar fix should go in the sample values? In the selction query builder interface, date values for a date field still appear as the UTC decimals.

Thanks,
Chris

Does anyone have a compiled fix for the date issue? it is showing some long number for the date??

Sorry for the late response, what you want to do is the following:
In utils\PagingQueryTask

add -> import mx.formatters.DateFormatter;

replace the function getDistinct Values with this function:

private function getDistinctValues(array:Array, fieldName:String, fieldType:String=""):Array 
  {
   //prepare result array
   var collection:ArrayCollection = new ArrayCollection(array);
   var distinctValuesCollection:ArrayCollection = new ArrayCollection();
   
   //prepare a temp working array
   var tempPropertyArray:Array = [];
   
   //loop over all the objects in the collection
   for each (var object:Object in collection) {
    //get the value from the object
    var propertyValue:Object
    // check the data type, add '' quotes if needed.
    if (fieldType == 'esriFieldTypeString' ||
     fieldType == 'esriFieldTypeGUID' ) 
    {
     
     propertyValue = "'" + object[fieldName] + "'";
    }
    else if(fieldType == 'esriFieldTypeDate')
    {
     var dateFormatter:DateFormatter  = new DateFormatter ();
     dateFormatter.formatString = "MM/DD/YYYY";
     propertyValue = "'" + dateFormatter.format(new Date(object[fieldName])) + "'";
    }
    else
    {
     propertyValue = object[fieldName];
    }
    //write the value as a property. If it exists it will be overwritten
    //which creates a distinct list
    tempPropertyArray[propertyValue] = true;
   }

This widget is a life saver! Thanks for posting the compiled version for 2.5. I'm still having a small problem querying dates. All the data for my viewer is in an ArcSDE database which automatically adds the time along with the date. When I use the widget and attempt to query a date it doesn't return any results because it needs a time (When I manually type in the time than it works). The widget doesn't bring up the dates with the time though in the list of unique values, only date alone. Is there a way to fix that or if anyone knows how to turn the time off in the date field that would work too.

Thanks the great widget!

Same SDK - 4.1 and AGS 2.5 It has the Date and Time formatter, but I don't have time data available to test this out. Can you work with the uncompiled version? If you can't work with the uncompiled version and this version does not work for you, I can abstract out the Date Time formatter into the config file (probably the best solution anyway), but I can't get to that for a few days, Maybe Tues or Weds.

Let me know if this at least helps

It's working perfectly now. Thanks for the help.

Hi!

I'm thrilled to have found a widget like this - thank you!!

But I'm running into a little snag...someone in an earlier post had the same problem, but I never saw a response to it.

I'm running Flex 2.4 and have downloaded the latest versions of the .xml and .swf files for the widget. Everything appears to run smoothly except that when I try to query the 'get unique values' doesn't populate automatically for the field I'm trying to query against.

Am I missing something? I'm fairly new to Flex so it could be a pretty basic 'something' that I'm overlooking.

Thanks a million!!

Hi Caroline! You aren't bothering me at all. 🙂

No, I still haven't gotten the issue resolved; I'm hoping someone who has will reply to the thread. I'll keep you posted if I ever get an answer.

Happy New Year!

HaroldBostic

Hello, I believe the issue of the unique fields not showing up is due to how the query works. I believe the field that you are having issues with is a non-string field. If that's the case and you are working with the uncompiled version:

in utils/PagingQueryTask.as around line 184, you want to change query.text = "%" to query.where = "1=1"

I'm almost positive that change is reflected in the versions with the date and time fix found here:

Hi again Caroline,

I think I might have solved my problem.

When I was pulling in the url for the layer in the SelectionWidget.xml file, I was using the FeatureServer service instead of the MapServer service from my rest services directory. (The layer I am using is editible also.)

When I tried using the MapServer url I got the unique values list to populate.

Hopefully this fix will be as easy for you!

Ashlee

CarolineCochrane

Harold and Ashlee - thank you both so much for your advice!

I have checked the layer's primary field is of type string. I have tested on a string field and also made the change: query.where = "1=1"; as per your kind advice, Harold, but the unique values are still not being returned unfortunately.
The links to the later versions of the widget are all compiled and as my viewer is customised quite a bit - i require a uncompiled version, do you know off hand if one is out there?

Kind regards and again thank you both for your help with this wee issue! 🙂

Hi again. I had posted earlier about the selection widget not bringing up the date and time together in the unique values field. You compiled a new version that fixed that but I seem to be facing another problem and I'm not sure if it's the widget or my own settings. I mentioned before that geodatabases store date and time together in a date field. The ArcGIS help menu says that date are stored as yyyy-mm-dd hh:mm:ss AM or PM. The time doesn't matter to me since the geodatabase seems to store random times that make very little sense. When I open up the selection widget and go to search by a specific date the widget brings up all the unique values but then fails to find any features. When I inspected how the dates were stored in the attributes and how the appear in the widget I noticed they were shown in two different formats. I'm not sure if this is the reason for why it can't bring up the results. I had it working fine with the same data yesterday. I attached some pics of the dates in the attribute field and the widget. I don't have the ability to change code unfortunately. If anyone has any ideas I'd appreciate the help 🙂

Thanks!

Mark,

I read that the unique values list does not populate if the underlying table does not have an object ID field. This presents an issue relative to using the widget to query mapservice layers that were created as event themes. Any possibility of a modification to overcome this issue?

Thanks you.

Keith

Hello,

Does anyone know if there is a record limit when finding the unique values? When I click on Get unique values it just says Processing 0 of 0 records and then it ends. If I use a smaller subset of the same data it works fine.

Any help would be appreciated.

Just wondering if anybody else is having this issue...

When there are more than 1 query results the widget works flawlessly..
When there is only 1 query result, the pin icon for the selected feature disappears, my map scale goes into the negatives, and all features in all layers disappear...its as if im on the other side of the basemap lol.., also the info popup for the selected feature moves around the map as i zoom....

mgiles86

I have figured out the problem..in case anybody else is experiencing this issue:

In selectionWidgetUtil.as there are two functions (getGraphicsExtent() and zoomToSelectedFeatures()). Inside each of these functions there is a block of code that deals with creating a new extent around a single point, to allow zoom to selected features when only one point is selected. Inside these code blocks, a new extent is created (called result or graphicsextent).

When the new extent is created, the original code read : [graphicsExtent = new Extent(myPoint.x + 50000, myPoint.y + 50000,myPoint.x - 50000, myPoint.y - 50000, null);] where myPoint is the selected feature. However, when a new extent is created, the proper syntax is: [ new Extent(xmin, ymin, xmax, ymax, spatialReference)] NOT [new Extent(xmax, ymax, xmin, ymin, spatialReference)].

I simply changed the code to read : [graphicsExtent = new Extent(myPoint.x - 50000, myPoint.y - 50000,myPoint.x + 50000, myPoint.y + 50000, null);] and the problem is solved!

DianeWhited

Burns86 - I think I am experiencing the same problem. I have data the covers the international dateline and when the selection finds data on both sides of the dateline - it zooms way out to cover the whole globe. Do you believe your solution would work for me?

If so - I don't have the uncomplied version, just .swf and .xml for flex 2.4. Could you send me complied version or uncompilied data for 2.4?

Thanks.

MarcinMielewczyk

That's right this wdiget is w*ak*d. you are great.

I am experiencing small problem with this widget, namely, when it is in Selection Results tab and I click on one of the results - my flesh crashes.it might be because my FW 2.5 is a bit customized comparing to the original one - I hoped that I could fix it on my own but I can not find source code. So, I was wandering if you could put on the forum uncompiled version of you widget for FW2.5?

Thanks,
Marcin

MattPohl

Hello all-

First off, great widget, it works great and we use it all the time. Just wondering if anyone has modified it to include the ability to select from the current selection? Is this even a possibility? I have received many request for this function and agree that it would add to the power of this widget. Any insight would be appreciated.

MarcinMielewczyk

Hi all,

Each time, when I use the widget I am impressed. I would like to repeat our colleague request, namely:I'd like to see the Unique Values list use the coded domain values (like the info popup).
Would it be possible?

And another thing: is it possible to put on the forum uncompiled version of the widget for FV2.5?

Best regards,
Marcin.
