Problems editing items in property sheet [message #445723]

Hi,

I was trying to modify the Flow example of GEF to test and wanted to add
couple of more items to the property sheet of an Activity.
I do see the items in the sheet but when I try to change the values, I
get the following error.

Unhandled event loop exception
Reason:
Assertion failed:

I have added the property as a TextPropertyDescriptor and also taken
care of it in the getPropertyValue and setPropertyValue along with
writing a getter/setter for the property and calling firePropertyChange
in the setter.

Am i missing somethings?

Thanks

Property sheet is provided by the UI team. You should ask this question in
the eclipse platform newsgroup:

This usually occurs because a null was set into the cell editor. The
stack trace in the .log file will usually pinpoint where in the code the
assertion was and so you can look at that assertion and see what was wrong.

Thanks Rich, the log file does give me some lead.
