Description Lysathor

2010-06-08 11:28:05 EDT

Sorry for not providing correct Product, Component etc. but I do not know the abbrevations, components etc. So I let the pre-selected values. 
I hope the stack trace helps.

What steps will reproduce the problem?
Editing schema and/or types using eclipse gui (design view)
I cannot reproduce it by a specific action, but it happens often. Last time it happened, it was when adding an enumeration type.

It seems to be related to Design View.

Hi, thanks for reporting this.  I cannot reproduce this.

Please retry on the latest driver and reopen with the steps to reproduce.   I don't readily see anything in the trace that will point me to where I should look in the xsd.ui plugin.
