> Hello,
> there is some problem with attribute/value quick filter.
> Start Apache DirStudio, open connection to LDAP server.
> Find a tree with some objects and some subtrees.
> Expand one subtree and keep other subtree collapsed.
> Open one object, enter some text to attribute/value quick filter - this will
> filter only those lines containing entered text in attribute/value field. [OK]
> Now, open other object on the same level and change the text in
> attribute/value filter. This will refilter the displayed lines. [OK]
> Now open some object from already expanded subtree and change the text in
> attribute/value filter. This will refilter the displayed lines. [OK]
> Now open some collapsed subtree. Select some object and try to change
> attribute/value filter text - this generates error
> "Error notifying a preference change listener. Check the log for details.
> java.lang.NullPointerException"
> If you have open some object and you expand some subtree, it will generate
> following message to the log:

> If you close object view before you expand some subtree, you can still use
> attribute/value quick filter. First time you expand some subtree while there
> is open some object, it breaks the quick filter funtionality.
