Dynamic Legend widget loads blank w/ Flex 2.1, ArcGIS 10.0

AshleyOwens — Tue, 02 Aug 2011 15:15:27 GMT

I downloaded and installed "Dynamic Legend Widget For Flex Viewer 2.4", hoping it would work for Flex 2.1.
To avoid error "Error #1069: Property version not found...", I had to comment 2 "if" statements: "if(layer.version >= 10.01)".
Now the widget loads, but is blank (see attached screenshot).

SOLUTION TO BLANK WIDGET: Map services were pointing to a 9.3 environment. When I changed my config.xml to a 10 environment, I saw the legend load dynamically based on the map!

Robert,
I have a flex 3 app using the 2.1 version of the dynamic legend and the client is complaining that sometimes the legend comes up blank. They say they get around it by refreshing their browser. Any ideas on this? I feel bad the client has to deal with it in this way but i'm having a hard time recreating and troubleshoting this issue. Your help is appreciated.

Thanks, Gary

Gary,

Way back then the images for the legend were getting created on the server in the output folder and the server has a configured amount of time before it goes and deletes all the contents of that folder. That is likely the issue. The clean up interval can be adjusted in Server Manager. If you would move them to 2.4 they would not have this issue.

Oh, I was under the impression that images in the output folder were deleted within minutes, not seconds? I would love to move them to 2.4 but this was a many thousand dollar custom app with a lot of code and there is no budget to migrate the whole thing to 2.4. We are just on the hook for maintenance. So am I understanding you right that within seconds after the loadLegend is called that if the app doesn't finish loading in time, the legend images will be deleted? Do I have any options short of migrating to flash 4 and api 2.4?

thanks

I went back and opened the folder while I was running the app and nothing was being added to the output folder for that map service. Seemed a little strange.

Gary,

No definitely not seconds or even minutes usually hours. I was guessing that this was the issue you were encountering, so this might not be it. This just a symptom I remember from back then that people who used the widget for several hours would have the issue because the image was deleted on the server.

!!!! EDIT Gary I was actually think of pre Flex Viewer 2.x... Sorry.

So the question is what service pack is the client using on their ArcGIS Server?

Robert,
It looks like the client is using ArcGIS Server/Desktop 9.3.1 with no service packs.

RobertScheitlin__GISP — Fri, 30 Sep 2011 16:53:28 GMT

Gary,

Hmm... If the client is using a 9.3.1 ArcGIS Server than you would have had to install the asp web service that made the SOAP requests to generate the swatches. Do you remember doing this? Is the legend issue actually sporadic or actually never works?

GaryBushek — Fri, 30 Sep 2011 17:36:21 GMT

Robert,
Thats odd because I never installed any asp web service. I have the widget that has the "generated\webservices\SoapLegendService" classes and from my code I specify the soap url which is the map service url without "rest". Has seemed to work in all the projects i've used it in (with the exception of the sporadic issues this project is having). And yes, it does work most the time. IE seems to have no issues with it, just firefox.

Gary,

Ahh... That is not my code then. No wonder I was scratching my head on this... Sorry I can't be much help to you as I don't have any experience using that code.

Robert,
ok, I thought you helped me once before with it but that must have been a different widget. None-the-less, you brought up a good point about the service packs as they are way behind. We'll give that a go and see if it helps.

thanks for your help

Hi,
I am having a problem with the Dynamic Legend.

As per the functionality it works fine with our network, but when I try to access the application outside of our network its display HTML output in Legend Window.

Though internal network Dynamic legend request generate legend images within proxyoutput directory. But when I access the application outside out network, map request gets successful and a temp image generate in proxyoutput, but not legend images.

I have configured CrossDomain.xml please find below the contents.

<?xml version="1.0"?><!DOCTYPE cross-domain-policySYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">

Hi,
I have this issue in our environment.

User request is been full fill through ISA proxy server. As per the current configuration Flex portal request redirect to port 80 for ArcGIS Server (Which is standard) but for Portal which is access through a tab in a sharepoint portal, request is redirected through a different port. Does these ports need to be same (same as ArcGIS Server standard porta 80).

Thanks & Regards
Deep

Hi Everyone,
Can some explain about the below mention error which appears in log of Dynamic legend web service. I believe the issue can be due to ISA proxy server setting as this same service works well when we try t access the portal within TSL network.
