Build Identifier: 0.7.0.v201109131140

1) Open the attached RUIHandler with VE.
2) Select the Button in the RUIHandler > Right click Button > Properties
3) Change the Text property to any other values
4) Select the GridLayout, and delete it.
5) Right click anywhere in the Design pane of VE, and click 'Undo'
6) You'll find the change made in the 3rd step is lost.

Maybe the root cause of the problem is the same as 358171 & 358176.

I set the defect as major, because the defect will confuse user.

Reproducible: Always
