Reproduced with last dev build.

Comment 1 Maros Sandor 2003-07-17 15:00:21 UTC

I think the problem is in the property editor 
implementation (trying to get "old value" of multiple 
properties before changig it).

Comment 2 Marian Mirilovic 2003-07-30 07:48:13 UTC

Vladimir:
could you try it again on current dev build, it is already fixed in my
opinion, thanks in advance.

Comment 3 sva 2003-08-13 11:26:43 UTC

Sorry, cannot verify that it's not reproduced due to bug 
35410

Comment 4 _ tboudreau 2003-08-18 12:30:23 UTC

Fixed - the problem was that the original value of the 
property was being fetched for comparison with the value from
the property editor.  The DifferentValuesException is now
caught, and if present, the properties will be updated with
the new value even if it occurs.

Checking in PropUtils.java;
/cvs/openide/src/org/openide/explorer/propertysheet/PropUtils.java,v 
<--  PropUtils.java
new revision: 1.9; previous revision: 1.8
done
