Robert,
I am working with flexviewer 2.5 and the un-compiled code for 2.5 in Flashbuilder 4.5. I have hit the site from multiple machines and still have the same issue, but when I run it from my development machine it works.
Which leads to believe something else is being compiled when the entire application is deployed, and if I use the deployed flexviewer app (instead of just replacing my locate widget) and replaced all my xmls and config. that it would then work. But I really do not want todo that.
Is this the recommended work flow? To have it all configured with modified xmls then compile and deploy through Flashbuilder? I have just been modifying individual widgets and replacing the ones in the compiled flexviewer.
