Identify Widget 3.1

GeorgePapamihalakis — Mon, 11 Feb 2013 20:01:21 GMT

Hi I just added this widget to my Flex - application builder site, and when I click on the icon nothing comes up. Not even an error message. Im sure this is simple, but what could I be missing? Any help would be appreciated. Thanks.

George,

Are you using Application builder 3.1? Did you upgrade and existing site created in an older version of App Builder?

Yes sir. It was an older site I created that I just upgraded to 3.1.

George,

Can you try an create a brand new site and add the widget and see if it works (I have seen traffic about people having issues with upgrading).

Just made a brand new site and added the widget and it works. What do I need to do to make it work with the old one?

Thanks for your help.

I just recreated my old map. I do have another question though, I cant seem to be able to select only certain layers to identify. I removed the default layers, so now all I have is the All Layers selection. Do I need to manually put in all of the layers to Identify?

George,

The only layers that appear in the drop down are the ones that you manually configure in the widgets xml

All,

Version 3.1.4 is now available and is a strongly recommended update if you use the Identify widget along with other widgets that add layers to the map.

* 3.1.4 - Fixed a bug when an unsupported layer is encountered in the map an RTE (Runtime Error) occurs.

Hi,

Thanks for this widget. But I don't know if this is an isolated case, I found something a bit puzzling because when I use 'Imagery with Labels' or "Terrain with Labels' in the Featured Basemaps as basemap to my application, the Identify widget suddenly doesn't work (ie, it doesn't do/prompt anything after a selection). Any other basemaps the widget works. Is there a setting to the Identify widget that I am missing? Or is there some conflict somehow with the nature of the aforementioned basemap tiled services? I have set <excludebasemaps> tag to true. Thanks for any insight.

Cheers,

JJ

JJ,

It has to do with those particular base maps not supporting the identify operation if you look at their REST service directory page all the way at the bottom is the list of supported operations.
Supported Operations: Export Map Generate KML for those two notice the absence of Identify

Where the other have it:
Supported Operations: Export Map Identify Find Generate KML

Hi Robert,

Thanks, I understand, I will take that into mind. But shouldn't have the <excludebasemaps> tag handled that unsupported issue? I also tried using the <excludelayer> tag to no avail.

Also, interestingly, if at runtime I switched from a previously set 'safe' basemap like Imagery to that 'Imagery with labels' basemap, the Identify widget works as normal. Any further clarification is appreciated and I am very grateful for all the helpful widgets you have contributed to date.

Cheers,

Jj

JJ,

When you say

(ie, it doesn't do/prompt anything after a selection)

that is strange because the latest version 3.1.4 that I am testing when you click on the map it switches to the results view and state no results found and then a couple of seconds latter switches back to the identify tools view.

The "Imagery with Labels" in my testing does return results identical to the result that the "Imagery" basemap returns.

In my testing it is only the "Terrain with Labels", "Light Gray Canvas", "USA Topo Maps" and "Streets" that produces no results.
The only Basemap that just cause the widget to do nothing is the "OpenStreetMap" as long as I have onlythese set to false?

<layers onlythese="false">

If you set it to true then you need to list each basemap in your layers list for the IdentifyWidget.xml

Hi Robert,

Thanks for the feedback and taking time to test. Yeah it is strange that it behaves differently on my end as I am also using 3.1.4.

Sorry for being a bit vague though, but my problem wasn't about the basemaps not returning results, actually I don't want them drilled for info by the widget, hence my use of <excludebasemaps> tag to true. My problem was the presence/ absence of a particular basemap somehow affects the functionality of the identify widget across my operational layers regardless if <excludebasemaps>,<onlythese>, <excludelayer> settings were set appropriately (I think). I'll check my config again, thanks.

Cheers,

Janssen

Janssen,

Strange... The more detailed info you provide the more support I can provide. The use of the excludebasemaps should not have anything to do with operational layers.
