Description Palmer Eldritch

2012-07-21 10:46:54 EDT

Build Identifier: 20120614-1722

Updated from indigo to juno via Help > Find updates (I added the juno repos)

Since then control+space fails on templates (like sysout) and SWT. The relevant part of the log is :

I suspect you're seeing bug 244770.

So what should I do to get rid of this - I did have php plugin (which shows other errors in the log) but the problem appeared on update - and I had created a couple templates myself. Maybe it is not pdt related ? What should I do to make it go away ? Should I download Juno and drop it on top of my existing install - or will this break hell loose ?
This is really hindering me - I would submit a bug to the pdt if needed - should I ?

Still a workaround would be much appreciated :)

Just remove those bundles from your install.

No. You should install a clean download and then add things that are missing via Help > Install New Software...

Maybe you have an old version of PDT. The problem should be fixed, see bug 244770 comment 12.
