This morning I started up Eclipse and attempted to switch to design mode when GWT Designer Initialization fails (the error log is below). It literally worked fine yesterday and does not work today, and nothing has changed in my configuration or source. It broke while I was sleeping.
A few points:
1) Running GWT 1.5.2, OS X 10.5, Eclipse 3.4
2) It broke on two machines at the same time (they share projects via SVN)
3) All source files in the project I was working on fail in the same manner.
4) A new, virgin project does not fail.
So the conclusion is that there is a problem related to this particular project which propagated through SVN. But what is odd is that it spontaneously broke when I was sleeping.
It is not a general problem with GWT Designer or GWT because it works with a new, virgin project.Any suggestions to get GWT Designer working again would be appreciated, I really need it!
TIA
Ciao,
Rick
