Hi,
I get Exceptions on initialisation of my view. Below is an excerpt of the
almost 2000 lines of exceptions messages (3.0 M9)
I guess this says that running the constructor of my view failed, might be
for missing dependencies.
How can I find the real cause of the Exception and find out, which Class
exactly is missing? I think this is not very well-behaved of Eclipse to
hide an Exception cause.
Thanks,
Juergen

I finally found out the solution.
In plugin.xml I had
<plugin .... class="test.ui.DataView">
instead of class="test.ui.DataPlugin"
This was a stupid typo. But still I think the exception thrown could be
better formulated as
!MESSAGE Plug-in "test.ui.Data" was unable to instantiate __plugin__ class
"test.ui.DataView".
