Enhanced Search Widget for FlexViewer 2.1

RobertScheitlin__GISP

All Here is my next widget in the FlexViewer 2.1 series

Special thanks to Erwan Caradec for contributing to this code.

The Enhanced Search Widget extends the standard search widget with a floating data grid and a new spatial query w/buffering.

Robert,

Sorry, didn't explain that well at all! Probably easier to just see what happens in action:

http://gis.calhouncounty.org/FlexViewer2.4/index.html?config=config-eSearch.xml&search=I-64&slayer=4&exprnum=0&showdatagrid=true

Use the graphical search polygon tool to select some parcels. Then, right after the selection has been made, keep drawing on the map and make a new polygon...the user has the ability to draw as many polygons right after one another as they want.

Now do this using the rectangle tool. It works fine to draw another rectangle right after the first rectangle as long as you "hold down to start and let go to finish" but if you just single click on the map it will go ahead and make a new selection without actually letting you draw a new rectangle...

Sorry for the confusion...hope this is clearer

RobertScheitlin__GISP

Phillip,

Well I feel pretty dense here, as I still have no clue what you are talking about....

Bad choice of words...what I mean is the polygon tool goes right back to the drawing state after a polygon has been created, whereas the rectangle tool makes a new selection with a single click after the first rectangle has been drawn. They actually do not behave identically...I double checked using the code gallery link to widget and tested it using the parcels layer....

by drawing state are you talking about the widgets state being the results state (view) and or the graphical search state?... I just can't wrap my head around what you are trying to point out here.

Philipp,

You have never been prompted in my widget.

The rectangle tool works identically to the polygon tool...

I will fix this in the next release.

If you selected a graphical selection tool and then never draw anything on the map, you would have to hit clear on the graphical selection view to disable the currently selected draw tool.
Ahh, that would make sense...

Thanks, Robert!!

Hi Robert
Searched the thread and looks like Joins are supported, and specifically mentions relates not supported for now back in Jan. Just wondering if you've considered supporting relates now? This would be very useful to enable the creation/export of a parcel mailing list.
Thanks, all the best
Steve

They both use the same spatial reference.
Looks like it was something in the config file in the spatialrelationships section.

I was using the previous config file, .6 or .10. Just copied the section from .12 over to it and it works fine.

Thanks !!

Nestor.

RobertScheitlin__GISP

Nestor,

Sounds like you have something screwed up in your config. What spatial reference are you using in the SearchWidget.xml? is it the same as your buffer distance widgets config file?

RobertScheitlin__GISP

John,

Changing the label of the widget should not be a problem.

Changing search to SEARCH is OK if you are using the uncompiled code and update these lines:

if(ViewerContainer.urlConfigParams.SEARCH != null){
                    callLater(queryFromURL,[ViewerContainer.urlConfigParams.SEARCH,ViewerContainer.urlConfigParams.slayer,ViewerContainer.urlConfigParams.exprnum]);
                }

Philipp,

Noticing some odd behavior when using the select by rectangle tool.
After the initial selection is made (on a parcel layer) clicking anywhere else on the map will
create a new selection without being prompted to draw a new rectangle.

You have never been prompted in my widget.

This should work the same way as the select by polygon tool - after the initial selection if you
click elsewhere you must redraw a new polygon to create a new selection.

The rectangle tool works identically to the polygon tool...

Also, when closing the tool the selection is cleared, but the buffer remains...

I will fix this in the next release.

And...when drawing a rectangle there is a tooltip 'Press down to start and let go to finish'
that hangs around even if after you select to do a text search...

If you selected a graphical selection tool and then never draw anything on the map, you would have to hit clear on the graphical selection view to disable the currently selected draw tool.

Good Afternoon Robert,
Hope all is well.

Having an issue with 2.4.0.12. When I create a spatial buffer, it buffers my entire extents, regardless of the distance and unit.

Using the Buffer widget works fine. The buffer is the correct distance and unit.

I'm on 10, sp 3, fv 2.4

Thanks !!

Nestor.

Robert,

Questions on the Enhanced Search Widget... Can I change the name of the widget in the config file or does it break the url search function? Also, is it possible to change "search" in the URL to "SEARCH" if I am using the uncompiled version to save me the headache of changing a bunch of links on an outside site that hits the viewer? I am currently making the jump from an older version of your esearch widget (2.2.10 I think) to the latest version. Thanks!

Michael,

Do you have your shape and/or ObjectID fields hidden in the MXD? If that is a problem.

Nope. That fixed it. I suspected something to do with the layers. Thanks for pointing me in the right direction.

RobertScheitlin__GISP

Michael,

Do you have your shape and/or ObjectID fields hidden in the MXD? If so that is a problem.

MichaelZierten

Yes. Actually I misspoke on my last post. I get the error when I try to use the graphical search. When I use the text search, I get nothing.

RobertScheitlin__GISP

Michael,

Are still having issues?

MichaelZierten

Michael,

You need to be a little more specific.. When do you get the error when you attempt to launch the widget, when you click search?

when I enter a value in the window and hit the search button.

I'm not having much luck getting the widget to work. I get the following error:

Error #1009: Cannot access a property or method of a null object reference

I'm using the precompiled version, flexviewer 2.4. Here is the Layer config:

<layer>
   <definitionexpression></definitionexpression>
   <enableexport>true</enableexport>

I've verified the attribute fields in my rest services.

Hurray! You're the best (figures it was something little). Many thanks... 😮

RobertScheitlin__GISP

Sheri,

Yep you deleted the right carrot on each...

<expressions>
    <expression alias="Parcel ID" textsearchlabel="Search parcels by ID [Example: 102.6-2-9]"> upper(TAXID) LIKE upper('%[value]%')</expression>
    <expression alias="Parcel OWNER" textsearchlabel="Search parcels by OWNER [Example: Smith, John]"> upper(OWNER1) LIKE upper('%[value]%')</expression>
    <expression alias="Parcel LOCATION" textsearchlabel="Search parcels by LOCATION [Example: 139 Pack Forest Rd]"> upper(PROP_ADDR) LIKE upper('%[value]%')</expression>
</expressions>

SheriNorton

Hi Robert,
You're correct - these are not domains. I adjusted the EXPRESSION as you recommended, but now an Application Error (#1090: XML parser failure: element is malformed) displays when the Flex Viewer loads.

Here's the changed XML code:
<expressions>
<expression alias="Parcel ID" textsearchlabel="Search parcels by ID [Example: 102.6-2-9]" upper(TAXID) LIKE upper('%[value]%')</expression>

        <expression alias="Parcel OWNER" textsearchlabel="Search parcels by OWNER [Example: Smith, John]" upper(OWNER1) LIKE upper('%[value]%')</expression>

        <expression alias="Parcel LOCATION" textsearchlabel="Search parcels by LOCATION [Example: 139 Pack Forest Rd]" upper(PROP_ADDR) LIKE upper('%[value]%')</expression>

</expressions>

Can you tell if I zapped too much code (or should add additional elements)?

Thanks!!!

RobertScheitlin__GISP

Sheri,

So the TAXID, OWNER1, PROP_ADDR field have a code value or range domain associated with them in your mapservice???... Judging by their names I would not think so. If they in fact do not then remove the field and usedomain attributes from those expressions.

Hi Robert,
First - thank you SO much for this widget! I'm using the Compiled version for Flex Viewer 2.4.

I have just one problem that I'm not sure how to tackle (sorry, newbie here):
1. Error message when any of the three Text Search options I've set are selected:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

If I click "Continue" the error clears and the search works just fine!

Robert,

ok.

Thanks for your prompt resoponse.

RobertScheitlin__GISP

Paul,

None of those are possible in the compiled version.

Hi Robert,

I'm using the 2.4 version and I'm trying to figure out how to remove the select by point and select by line buttons from the Graphical Search part of the widget.

Also, is there any way to modify the size of the datagrid and popup windows?

Thanks!

MarkHanway1

Robert, I would like the user to only be able to search one or two layers defined in the xml. Build a buffer, then find seperate point locations defined in the xml spatially within the buffer.

For instance the user would select to search a city or neighborhood layer. The widget zooms to that location from the selection results. The user can then build a buffer, then spatially find point locations from seperate layers defined in the XML such as Hospitals, Points of Interest, etc.

The xml already lets you specify which layers can be located spatially, what I would like is to filter out or limit the layers that can be searched on the text input page. hth...thanks, Mark

RobertScheitlin__GISP

Mark,

What is your use case for this???... I can't seem to imagine why you would want that.

RobertScheitlin__GISP

Emily,

Maybe soon. It is always a lot more complicated than end users imagine to do enhancements like this.

MarkHanway1

Robert,

Thanks for the latest enhanced search widget...this is really great, thank you. I love the option to limit the layers that can be included in the dropdown for the spatial search.

I would like to have the same thing happen on the Text Input page. Is it possible to limit the layers in the drop-down for search layer on the Text Input page?
