This bug depends on bug 479113 to be able to create a proper unit test.
althouh the bug 479113 is close, the crashed problem still exists. On Gui do: 1. contract "Accessibility" 3. contract "Appearance" 4. contract "Behavior" 5 contract "Data" 6 contract "Focus" 7 contract "Layout" the sample crashed. test on: mono-core-137655-1415.src.rpm mono-uia-132785-276.src.rpm uiaatkbridge-137646-669.src.rpm uiautomationwinforms-137656-678.src.rpm Revision: 137666
Fixed in trunk r137705. Felicia: right, the dependency was set in order to be able to do a unit test for this one. Fixing the dependency doesn't mean this is fixed, but rather than I can start working on it :)
It works very well:) close on: mono-core-137753-1429.src.rpm mono-uia-132785-276.src.rpm uiaatkbridge-137705-670.src.rpm uiautomationwinforms-137705-679.src.rpm Revision: 137759
