URGENT I am getting a Parse error when I try to use designer

[LORDs_diakonos]

I am only getting this in Linux. On a different machine in Wondows it worked fine. See stack trace below.

OK apparently it does blow up on windows. It ididn't at first but when i shut eclipse down and restated it the problem starting happening.

[Eric Clayberg]

The exception does not suggest what the problem is.

I need to know the exact version of Designer you are using, and I need to see a test case (ideally the window you are trying to edit).

[LORDs_diakonos]

ok I am using the latest build I downloaded it today. I can paste my code but you won't be able to build cause of depenencies.

OK I got the designer to work a little though it still says "Unknown Window Type (Parsing Error)

I moved the tree out of the listener. I was going to do that anyways as I was just testing some things out.

What is the problem with the unknown window type though?

[Eric Clayberg]

I could not reproduce the parsing problem, but that is likely due to the fact that I don't have all of the referenced pieces.

Were there any entries in your log file? The reason for the parse error should be listed there.

Does that happen even if you close and re-open the editor?

It worked after I restarted eclipse

Was there ever anything in your .log file indicating the cause of the parsing problem?
