Bug 325788

Description Holger Staudacher 2010-09-20 15:18:27 EDT

It seems that we inherited a known JFace bug (bug 226155) . The FilteredTree assumes that the parent uses GridLayout. If not a ClassCastException will be thrown while running the TSD (see StackTrace below). 

Reproducible: always

Workaround: Use GridLayout on the parent.

StackTrace:
