I am using Eclipse Visual Editor 1.0. After I create a visual class and a
simple gui with a few components in it all is well. My problem comes when
I alter my main to create an instance of the frame and then when I run the
app the form is displayed but my display panel goes blank and the Java
Beans panle where my buttons or textfields were previously goes blank. The
code appears to remain the same.
I am running eclipse 3.0.1, EMF 2.0.1, GEF 3.0.1 and VE 1.0 (installed via
eclipse update, normally do it by zips so may try that as well). Ran first
time with eclipse -clean as per faq but it seems to work ok in general as
far as I can see.
Restarting the editor doesn't help. It doesn't bring back the layout.
Does anyone know does it use tags to help it rebuild the code like some
other gui layout tools or does it do it all by source...
(brings me back to the good old days of fighting visual crape 3 to develop
swing apps)

Yeah, the exception log is key for diagnosing issues such as this. I
could recognize this exception based on other people running into the
same problem earlier.

Just to clarify I'm using ve 1.0.1 (mea culpa, still thought I was on 1.0)

Same configuration, same problem.
Happens in the most trivial circumatances:
1. Create a visual class
2. Test without chaning
3. Close/reopen in VE
4. Class does not reappear in VE
Here is the log, specifically for loading a class in the VE editor:
!ENTRY org.eclipse.ve.java.core 4 0 Oct 19, 2004 18:31:55.199
!MESSAGE Exception thrown.
!STACK 0

Hi Iztok,
Remove the EMF examples plug-in from your Eclipse installation and it
should work fine.

That works now.. thanks a lot for that... just curious how did you know
it was the emf samples causing the problem?
Could you tell from Iztoks logs?
