Property View/Editor Recursive Exception [message #309736]

Originally posted by: hcurtis.xaware.com

If I select one our views and an item in the list the Property View is
correctly updated with the information of the selected item. I can select
other items in this view or other views with no issue. I can also complete
the edit by either entering return or selecting another property in the
property view with no issue,

However, if I

1. Select an item in another view
2. Then click on a property item which enables its editor in the
property view
3. Then select another item in any of the other data views available

I get the following Error Log:

It appears to me that the editor is trying to shutdown after the other view
was selected and enabled. Can someone suggest the action I should take to
avoid this error?

It looks like a spurious activation event from the Property view.
Unless you are noticing bad behaviour it shouldn't hurt anybody :-)

I'd open a bug at https://bugs.eclipse.org/bugs against Eclipse Platform
UI and include your usecase and that stack trace.

Later,

Do you have a selection change listener updating the property view as
you move to that other data view? That can generate that recursion error.
