Flex Viewer 2.2 gets Stuck

[SimonMorgan]

When using a widget that zooms to a location (enhanced search, bookmarks etc), the viewer soemtimes does not refresh the map. It just has a white background or stays pixellated. Has anyone else experienced this? I have added a number of widgets, some of which have not explicitly been modified since 2.2 was released. However, this does happen with 2.2 release widgets also. I am using Bing as my base map. Switching base map does not cause the map to refresh either. It does not seem to happen at a specific time interval nor is it predictabl;e when it will happen with a specific widget. Anyone have any thoughts?

Could you keep an eye on the http requests and response that are going through with tools such as firebug/httpfox fiddler so that when ever you see viewer not refreshing the map, its cause can be pinpointed.

So I managed to reproduce my issue, this time with fiddler running (attached file si the output). What is interesting is that I used Robert's enchance search widget. When I drug aselection polygon over the area, it produced results highlighted with the red selection graphic. However, when I did this, fiddler was no longer logging. It stopped logging when flexviewer got stuck after I zoomed in and then zoomed out. I am using Bing as my basemap.

Attached request and response didnt help. Do you have debug version of flash player? if not could you try installing debug version of the player so that it can throw runtime error to help figure out the cause.

Here is the output from the debug version of flash after I click to open an esearch widget:

This error occurs if you use ArcGIS Flex Viewer 2.1 compiled widget with 2.2 Viewer.

Try compiling your entire source with 2.2 (including all your widgets) This should fix this error

There was change made in 2.2 to get rid of following warning  that was reported in http://forums.arcgis.com/threads/13542-Flex-4.1-SDK-Warning-with-FlexViewer-2.1?highlight=warning

Docs will be updated with this information.

I only compile with flexviewer 2.2. Although I do have a couple of widgets that have not been updated sicne 2.2 was released. Should I remove these from my code and then compile again?

[MehulChoksey]

Yes. Give that a try

[RobertScheitlin__GISP]

Simon,

   Are absolutely sure you are using the right compiled version with the particular version of the viewer you are on? I think these errors are associated with the wrong version of the swf being used.

[SimonMorgan]

Yes. Give that a try

Figured it out. I narrowed it down to one widget. When I originally upgraded to 2.2 I modified the existing esearch widget config file I had to match the new format as mentioned in the important changes document that downloads with the widget. Well I must have done it wrong because I just re-did my esearch config files from scratch (using the config file that you incldue int he zip file as a template) and now I do not have a problem, even with widgets compiled that do not explicitly support 2.2.
