With firefox or OmniWeb it works just fine (cannot try with safari because of an api
issue). 
GWT Plugin for Chrome bug? sorry if the wrong place to post this.

I also ran into this problem on Windows 7, just out of the blue. Everything completely
stopped working in both Chrome & FF.

Things went back to normal after deleting gwt-UnitCache and restarting eclipse and
using IE with cleared cache to do the first load. (last part seems a bit voodoo - I
don't know if that's what made the difference)

I had the same problem and what helped was to use the correct Eclipse "Web Application"
Arguments set from the run configurations.

OS: Ubuntu 11.10
Java: 1.6.0_33
GWT: 2.5.0.rc1
Browser: FF 11

Same issue. Clearing Chrome cookies and cache worked for me.

For me, my solution is to delete my Eclipse projects and do a Maven re-import, which
temporarily fixes it (until my next rebuild).

Same issue with:

Can someone post a small example that reproduces the issue?

Clearing Firefox cache fixed it for me too!
