SmartGWT/Eclipse/Plugin -- can no longer debug

[ohmi]

SmartGWT 2.5, GWT2.4, Eclipse 3.6, OmniWeb browser

Since Firefox has made it impossible for Google to keep up with their plugin, I was using the OmniWeb browser. But now I am getting spurious errors like the one below or a ClassCastException performing the same operation when I debug or run with the development mode plugin.

Same operation (clicking on an item in a listgrid, causing new forms to appear) can also throw a ClassCastException:

I suspect my environment is somehow borked after upgrading to smartGWT 2.5 or something else. I'm looking for advice about how to reset/rebuild the environment.

Thank you.

Using an unsupported browser isn't going to help. Keep an older Firefox install around instead.

Good point. FireFox 6 has a GWT plugin available, I'll try to get that one back.

Oh yeah. I'm on a Mac. Anyone know where old versions of FF for OSX exist?

Found one here: http://mac.oldapps.com/firefox.php

And that seems to work. Firefox 6.0.1 with the GPE from 20 Sep doesn't throw those exceptions.

Thanks.
