Change LayerList Description from REST Endpoint to Layer Info

EoghanMcCarthy1 — Fri, 22 Jan 2016 10:41:29 GMT

Hi,

I want to supply some basic layer information under the LayerList Description instead to the default redirect to the REST endpoint.

Previously when using Flex I would edit the eLayerList config <usenewesridescription>false</usenewesridescription>

This would then provide the layer description included with the published layer.

Is this function possible in WAB or is there another method to providing background info for your layers?

Thanks

Eoghan,

There is nothing in place for this currently but a simple replacement of the [instal dir]\server\apps\[app #]\widgets\LayerList\PopupMenuInfo.js with the on attached here will give you the same result you had in Flex minus the ability to configure if the rest endpoint is used or the desc info. This file will show the description and copyright in a message dialog instead of the rest endpoint for that layer.

Robert,

Thanks, that is exactly what I was trying to achieve. I have the layer info window in operation but the values are being returned "undefined".

I have descriptions and copyright text in place, for example:

Layer: Natural Heritage Areas (ID: 6)

Is there an additional step required?

Many thanks again for your assistance.

Eoghan

Eoghan,

Hmm.. Let me do more testing. Is all your layers coming from the web map or are you also using the local layer widget?

Re: Change LayerList Description from REST Endpoint to Layer Info

EoghanMcCarthy1 — Fri, 22 Jan 2016 20:37:05 GMT

Yes they are, all coming from this webmap:

I haven't used the local layer widget yet. .

Any other info that can assist let me know.

Thanks,

Eoghan

Eoghan,

OK I found the issue and updated the code.

Thanks for that Robert.

Much appreciated.

Hi Robert,

Do you know if this will work for an implementation using the LocalLayer widget?

Thank you,

Bill

Bill,

I believe my testing involved LL widget.

Hi Robert Scheitlin, GISP‌,

You provided this great bit of code for me a number of years ago (attached above, under correct answer - PopupMenuInfo.zip) and it has been vital for one of our applications since. On clicking "Description" in the layer list it loads a popup that shows the description and copyright in a message dialog instead of the rest endpoint for that layer.

We have since updated our version of WAB Developer Edition (2.12) and since this update the "Move Layers" (up/down) functionality is unresponsive in the Layer List when we are using the revised code you produced. Would you know off hand what might be causing this in the code?

Many Thanks,

Eoghan

Eoghan,

Here is a 2.13 version of it.

Re: Change LayerList Description from REST Endpoint to Layer Info

EoghanMcCarthy1 — Mon, 23 Sep 2019 14:14:15 GMT

Many thanks for the speedy response Robert,

I am tied to version 2.12 at the moment as the environment the app is sitting on has just undergone a penetration test so I can't rebuild in a different version.

I did a test of what you sent in version 2.13 though, and it didn't work as expected. Upon clicking on the layer options to access the description, I am just getting a load spinning icon and no pop up - see below. Note, I have group layers in place here and they might be affecting things as I am getting a popup if I click on the group layer name.

Thanks again,

Eoghan

Are there any errors in the browsers web console?

Re: Change LayerList Description from REST Endpoint to Layer Info

EoghanMcCarthy1 — Mon, 23 Sep 2019 14:31:09 GMT

Nothing that I can see bar a few font errors. Strangely, it worked once for a single layer.

I've set up a test module to try and configure it.

OK. I see the issue. Corrected attachment is attached

The "Description" option is grayed out now.

Re: Change LayerList Description from REST Endpoint to Layer Info

EoghanMcCarthy1 — Mon, 23 Sep 2019 15:12:16 GMT

Just to elaborate on that a little further. Looking at the test module that I have set up. If the "Description" feild of the REST service is blank, a (blank) pop up loads. Where there is content in the Description field, the Description option in the layer list becomes grayed out.

Thanks,

Eoghan

RobertScheitlin__GISP — Mon, 23 Sep 2019 15:30:48 GMT

OK. Lets try this again.

Re: Change LayerList Description from REST Endpoint to Layer Info

EoghanMcCarthy1 — Mon, 23 Sep 2019 15:47:12 GMT

That did the trick!!! Yes, working nicely on the 2.13 app.

Do you think I'll be able to replicate those code changes back to 2.12 or were there wholesale changes to that widget?

Really appreciate your help on this.

Thanks,

Eoghan
