Identify Widget for FlexViewer 2.1

RobertScheitlin__GISP

All,

I have been waiting for the Final release of the FlexViewer 2.1 before I started to push out some widgets I have been working on.

Here is my Identify Widget for Flex Viewer 2.1. I have tested to ensure proper functioning with FlexViewer 2.1 and am now releasing it to you since the API Team did not get one into the FlexViewer.

Here is the link:

More FlexViewer 2.1 widgets to come stay tuned...

Stephen,

If you are trying to display fields that are from a join than yes you have to use the full join field name. I have not had any time to look into the _ issue so any info you guys give me on what is and is not working would be helpful.

DavidAllen

David,

that is what I was afraid of... The info popup that you want to have the alias for is not part of the identifyWidget code it is part of the FlexViewer base code.

Hey - that's cool. I cover that in my instructions, so users should figure out what to do.

I noticed today that the identify widget displays the hyperlink icon for all records of any layer that has a linkfield specified, even if the particular record's linkfield is null. Ideally I'd like it to work like the basic searchwidget: if the linkfield is null the link icon should not appear and clicking the link shouldn't open a blank web page, if the linkfield has an actual value, the icon should be visible and clicking the link should open that link.

Is this an easy change to make? I was guessing perhaps line 506:
if(link!="")
only looks for empty strings instead of nulls? So I just need to make sure that the link isn't an empty string AND is not null?

Thanks for any thoughts. I'm using the latest version of the widget (2.2.1 from 12/17).

GeorgiannaStrode

Jon,

We had the same issue -- apparently we have some spaces in our data.

We solved it by using:

if (link.charAt(0)!=" ")

Hope this helps.

I have 2 questions on the Identify viewer:

1. I'd like to show some layers even if they are not turned on (Section-Township-Range). I have edited the xml to change 'visible' to other options with no success. I've also edited the mxml code to comment out the test for visibility but that didn't work either.

2. How to suppress the message "Identify operation not allowed on this layer"

Thanks in advance!

RobertScheitlin__GISP

Georgianna,

1. have you set the onlythese="false"

2. Here is the code to be changed:

   //on fault
   private function onFault(event:FaultEvent):void
   {
    if(event.fault.faultDetail != "Identify operation not supported on this service")             
     showMessage(event.fault.faultDetail, false);         
   }

RobertScheitlin__GISP

Jon,

I am working on that issue right now. I am thinking it is because you are using a prefix and/or suffix the link is never and empty string so you always get the link whether it is null or not. Can you verify for me that some of your fields that the link is set to do actually display with a null in them when you are looking at them in ArcMap?

I have <linkprefix> and <linksuffix> empty (xml is below). I'm attaching a picture of how it looks in the flex viewer for one of the null records, as well as how it looks in the source mxd (also null). Check out the last layer (Marine ERA) which has the most null values for era_rept. Thanks!

EDIT: I remove the extraneous portion of the xml for readability

<?xml version="1.0" ?>
 <layers onlythese="true">
  <layer>
   <name>Marine ERAs</name>
   <fields>EAA_MARINE,MARINE_STA,ERA_REPT</fields>
   <linkfield>ERA_REPT</linkfield>

Jon,

Here is the fix:

        if(fldArr.toUpperCase() == identLinkField.toUpperCase()){
         //concatenate
         if(value != "" && value != "Null")
          link = identLinkPre + value + identLinkSuffix;
        }

I will work on getting this in the code for the next version.

JonFisher

Thanks Robert, that worked perfectly for me.

Robert,

Could you please shed some light on this thread?

Sorry for addressing you from another thread. I don't know how to send you a private message. I would greatly appreciate your help.

I'm having an odd issue. When I run my application from the flash builder program to test it, the Identify widget is displaying information about my location in a pop-up box that points to the feature. It includes all the fields as well as a little picture that's associated with the feature. See Sign1.gif attached. When I compile this and view it through a web browser, none of this information is displayed with the feature. See Sign2.gif attached. Any idea what's going on?

David,

It looks like your production machine does not have access to the images. Are they in a virtual directory that is restricted in some way?

That's a good thought. Let me go take a look, and maybe get the server guys involved.

Thanks!

DavidAllen

Well that was the answer - the web server wouldn't send a jpg file out, but it has no trouble with a gif. So I changed the format of the images and they work fine now.

EddBlaine

OK. I've got a weird thing going on that I've been banging my head against the wall over. I've configured the widget to work with five different services - Parcels, FLU, Development projects, ParksPreserves and Zoning. The identify task works great with Parcels & Zoning but will not identify features from the other three services. I've double checked everything that I could think of - even switching the order of the layers in IdentifyWidget.xml and setting them to return one column only. No luck. If I set the <layers onlythese> tag to false, they will identify fine. I've posted the app I'm working on here: http://199.201.190.110//ParksPreserves My rest services are here http://199.201.190.110/ArcGIS/rest/services/ParksPreserves And my config file for the widget is...

Does anyone have a clue? Robert, have you bumped into this problem before? ANY help would be appreciated. Thanks!

RobertScheitlin__GISP

Edd,

The likely issue is that the layer name in the IdentifyConfig.xml has to match exactly with the name of the layer in the REST services directory.

<layer>
<name>ParksPreserves</name>
<fields>SiteName,Address,ZipCode,PhoneNumber,OperationHours,Weblink</fields>
<linkfield>WebLink</linkfield>
<linkprefix></linkprefix>
<linksuffix></linksuffix>
<iconfield></iconfield>
<iconprefix></iconprefix>
<iconsuffix></iconsuffix>
<zoomscale>12000</zoomscale>
<forcescale>true</forcescale>
</layer>

Should be:

<layer>
<name>Parks & Preserves</name>
<fields>SiteName,Address,ZipCode,PhoneNumber,OperationHours,Weblink</fields>
<linkfield>WebLink</linkfield>
<linkprefix></linkprefix>
<linksuffix></linksuffix>
<iconfield></iconfield>
<iconprefix></iconprefix>
<iconsuffix></iconsuffix>
<zoomscale>12000</zoomscale>
<forcescale>true</forcescale>
</layer>

and if that doesn't work than you have to escape the apostrophe with

&apos;

Robert,

I downloaded the latest version of this identify widget recently. I went through at set up the .xml and compiled the application using Flash Builder 4. It doesn't seem to want to build the .swf file in the debug folder, but will rebuild .swf files for other widgets.

Today I copied the .swf from the flex 2.2 compiled version into the debug folder and it works fine. I'm just curious why the other widgets will build the .swf but this won't for some reason.

Thanks,

Nate

RobertScheitlin__GISP

Nate,

Did you add it to your projects modules list?

NateRose

Robert,

Thanks, that worked. I never had to add them for other widgets but good to know!

EddBlaine

Robert,

You da bomb! I wasn't even paying attention to the layer name published in my MXD...just the service name. The widget works great! I hope you enjoy the developer's conference. You deserve a freebee.

Edd

RobertScheitlin__GISP

All,

A new version of the identify widget is now available. Based on several comments some enhancements have been made.

* 2.2.3 - Identify by point/line/extent/polygon are all now supported
- Info window will appear at the center of identified geometry now if returngeometryforzoom is set to true in xml file.
if returngeometryforzoom is true, when you mouse over a record the geometry for that particular record is drawn using the symbology defined in the xml
- The symbology used by the draw tools is now user defined in the xml
- Fixed an issues with link icon if prefix or suffix is supplied and a empty field.

MikeMartin

This is a great widget. I got the hyperlink to work, but my problem is I can not display the linkfield as an individual field in the grid or the InfoPopup. Ideally, I need that as the first field listed and to also be part of the hyperlink string. The field in the code below is Well Log ID. I tried listing the field twice in the fields list, makes no difference. Any suggestions appreciated. Unfortunately, I don't have a flex compiler, so can only edit the widget.xml.

<layer>
 <name>All water wells</name>
 <fields>Well Log ID,Aquifer Elevation,Bailing Rate,Depth to Bedrock,Bedrock Elevation,Pump Rate,Screen Length,Static Water Level,Total Well Depth,Owner,Owner Address</fields>
 <linkfield>Well Log ID</linkfield>
 <linkprefix>https://secure.in.gov/apps/dnr/water/dnr_waterwell?refNo=</linkprefix&gt;
 <linksuffix>&_from=SUMMARY&_action=Details</linksuffix>
 <iconfield></iconfield>
 <iconprefix></iconprefix>
 <iconsuffix></iconsuffix>
 <zoomscale>9027</zoomscale>
 <forcescale>false</forcescale>
</layer>

Mike,

Unfortunately this is just the way that it is in my widget and all of esris as well. The issue is that the field is either or (either it is a link field or a display field, not both). This is just a coding limitation. My immediate suggestion is add another field to the data if it is absolutely necessary to have both.

Robert,
is there any way I can display the results in the Datagrid one at a time,with navigational buttons (next and prev ) for multiple recs ?

Any suggestions ?

Luke

RobertScheitlin__GISP

Luke,

The answer is yes, it is possible, with some significant modification of the code. Do I have any plans to add capability like that to this widget? No, not at this time. Right now I don't have time for enhancements of my widgets, only bug fixes.

NitinBele

Thanks Robert,
Your confirmation itself brings confidence.I m able to implement the data grid for multiple results with next and prev options.

Now where to make changes to enhance the clicked point(Now its shows with a small blue color circle) for adding a glow and how ?

Luke

RobertScheitlin__GISP

Luke,

At the very beginning of the IdentifyWidget.mxml I declare the symbology, for the point it's id is ptIdentify. Then you could assign a glow filter to the actual graphic that gets added to the map.
