Nothing at all in hosted mode

[Slippy]

Okay, semi-literate linux/gwt newbie running Ubuntu Feisty.

Downloaded GWT 1.3.3 (i think) the other day, tried a couple of the
samples in hosted and browser modes, all worked fine.

Deleted it and downloaded GWT 1.4.1 - hosted mode didn't work.

Deleted it and put GWT 1.3.3 back - hosted mode still doesn't work.
Blank window with the address in the bar, nothing else. Same for all
the samples in the GWT folders.

Ubuntu performed some automatic updates (didn't make a note of what
was installed - wasn't anything related to this) between downloading
1.3.3 the first time and replacing it with 1.4. I may have also made
some system changes in this time, but I can't for the life of me
remember what changes I've made, or how they can affect GWT.

Can't find anything in the Getting started guide that highlights
anything I may be missing.

Most likely you're getting some kind of script error that's preventing
the module from loading. I would suggest downloading the Firebug
plugin for Firefox, as this will alert you to the error so you can fix
it. Make sure to set the GWT compiler -style flag to PRETTY as well,
so you can make sense of the error you get.

Hi,
When I updated to GWT 1.4 it worked ok first, but afterI restarted
the computer...
i got in the package explorer of the eclipse an exception error that
is pasted down [1].
when i used the green 'run', it gives an empty not responding hosted
mode result.
I will be thankful if someone can help me, what should i do?

Hi,
sorry for spamming. the previous problem is not valid anymore, without
any fixing..
but still, my hosted mode result still show nothing, most of the times
now is giving not responding empty browser, but the html title is
shown.
Reinier mentioned something i did not understand in this discussion
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/d3462215fbf6b47a/d66ab1b0a2af0254?lnk=gst&q=update+to+gwt+1.4&rnum=11#d66ab1b0a2af0254
is there any one can help?

Thanks for the response, Dan, but I'm not sure I'm following you
correctly.

How would firebug help? I'm not using firefox, I'm using GWT hosted
mode.

Nor should there be any script errors - I'm attempting to run the
samples that come with GWT straight out of the box. I haven't edited
anything.

They worked before, and now they don't.

[Sumit Chandel]

Hi Slippy,

I have a strong suspicion that the problem you're experiencing may be related to an issue on the Issue Tracker.

Issue #1105: http://code.google.com/p/google-web-toolkit/issues/detail?id=1105

Could you post up more specifics about any error messages you see in the hosted mode shell window or the hs_err_pid*.log file when starting up the samples in hosted mode? If your problem looks similar to Issue #1105 you may want to try and run a build from the latest source checked into the repository and see if that solves the problem.

Thanks,
-Sumit Chandel
