Hi,

to give EPF a trial, I followed the installation instructions and than
successfully started it.
To get familiar with EPF, I wanted to follow some of the tutorials. But
after the first steps I encountered a problem I could not solve by now:

Every time I double click on an item in the library (e. g. a task), the
editor, which should display the item's details, reports a
NullPointerException and only shows the stack trace I appended to this post.
I tried to use the latest as well as the 1.5.0 release of EPF. Both show
the same behaviour no matter which Java version I use (1.5 and 1.6).
What can I do to solve this problem?


Thanks and regards,

Sebastian
