Environment
Novell Vibe 3.x
Situation
If you have a filter setup such that it finds all entries created using Form X > attribute Y, then, when you modify this filter to add another attribute, say Form X > attribute Z, notice that the previous attribute selection disappears from the form.
Resolution
A fix for this issue is available in the Vibe 3.4 Hot Patch 1, available via the Novell Patch Finder.
