Xbase DetailPane factory interferes with my variables view [message #1690332]

Thu, 26 March 2015 12:08

Eclipse User

In my plugin I got my own view which extends VariablesView.
When i click on a variable in this view i get an exception shown below. (This happens only ones after starting eclipse, the second time i click a variable the error does not show)
My plugin has a IDetailPane and a IDetailPaneFactory but it seems that XbaseBreakpointDetailPaneFactory is also listening and tries to cast the variable to a breakpoint.

Why is this xtext class also listening and how can i avoid the error message?
I would appreciate the help.
