GWT Designer 3.0.1 & Eclipse 3.2 error

[costa_basil]

Hi:

I am the end of my wits with this thing. It was working fine until I started to get the error below. I tried every thing the faq from here http://download.instantiations.com/Desi ... GWTProblem suggested but nothing works. I had Eclipse 3.3.1 but when I try to open the class in design mode it freezes eclipse and I have to kill it.

I just don't understand what's going on, why all of a sudden it started to crash like this. Is gwt designer using IE behind the scenes or Firefox? The only thing that I did was to install firebug, a firefox add-on, but I find it hard to believe it would have an impact on the gwt designer.

Designer error occurred.
Reason:
Parse error or internal Designer error. See "Details" section.

After so many reboots and a night, the designer magically started working again...

Don't you love the software that fixes itself after each reboot ??

[Eric Clayberg]

From yoru log, it looks like something was interfering with yoru local JavaScript environment.

GWT Deisgner is highly dependent on active localhost communications and a working JavaScript environment.

Anything that interfers with that can prevent the prodct from working.

I don't know why rebooting would have made any difference other than turning off whatever was causing the problem to begin with.
