I'm using flex viewer 3.1 (I had to revert to an older version to get each widget I am using to work) and am having an issue that seems to come from Robert's TOC widget (3.1.5), or at least something else affecting it.
If I have the widget set to preload, occasionally it will seemingly freeze up during load and be blank. The map layers then do not load either. This forces the user to refresh, which usually clears it up. I have since changed things to have the widget not preload, however (again, occasionally) when opening the widget it sometimes comes up blank and forces a refresh in order to turn on/off layers.
I can't figure out what is going on with it or why it is only occasionally.
I found this thread which led to a change that I applied but I'm not certain that it is the same issue or not. I haven't had enough time to see if that truly helps or not so I wanted to see if anyone knows if this is definitely the solution, and if not, what is?
thanks! !
