Help! Experimenting with RAP I seem to have messed up my eclipse setup.
I changed eclipse's target platform to point to the downloaded RAP
target to experiment and "play" with RAP a bit (VERY interesting and
promising, BTW! )
But now I need to go back and continue working on my current project and
I can't launch my "normal" apps. anymore. When trying to launch them I
always get an "Application error" (see stackdump below).
What I did (or at least intended to do) is simply to reverse the target
platform change and select my original eclipse again. So, in analogy to
what I did when installing RAP, I went to Preferences => Plug-in
Development => Target Platform, browsed to "C:\eclipse" in the topmost
field and hit OK. Fair enough the list of eclipse plugins was displayed.
I was a bit anstonished, though, that also all plugins of the RAP target
were checked as well, so I unchecked that subtree (i.e. I only left the
"normal" eclipse target checked) using the "group by location" checkbox
and then hit OK.
But apparently that was not enough to switch my target platform fully
back again. I now always get this "Application error" when trying to
launch the eclipse plugin on which I am working using a runtime
workbench. What (else) do I have to do to change my settings back to the
original eclipse??? I have to admit, I obviously haven't fully
understood this target platform switching business (even though it
seemed pretty well described and explained in the RAP docu).
Could some kind soul please hold my hand and help me changing this back
to normal?
Michael

Hi,
normally a click on the "Reset" button should do the trick. Looking at
the stacktrace it seems that you didn't have all plugins needed in your
target. As said, try the reset button.
