I've tried -clean option, also I've already reinstalled installation (after finding update page) but that error is appearing in logs,

When it occurs?
Apparently it is logged just after I switch from code view to design view (just before design view is updated) for the first time within ide session,

regards,
Peter

This should now be fixed in the latest build. Thanks

[Eric Clayberg]

This was a side effect of adding MyGWT support.

[peterblazejewicz]

Hello,

thank you guys both!
I'll post feedback when updates will be available via update page,

regards,
Peter

[Eric Clayberg]

I'll post feedback when updates will be available via update page,

If you use the continuous update site, the updates should have been available immediately.

hi Eric,
yeah I know, for some reason I cannnot get updates installed by update manager, There is always error occuring during installation process maybe becuase of some network or server lag, I had downloaded .zip-ped release (from 22nd) and installed it,
issue is fixed,

regards,
Peter

Hmmm. We'll have to look into that.
