You should strongly consider migrating to the Smart table model contrib. I
wrote it exactly because the problems with Filtered were not easily fixable
with simple workarounds and patches to the code. That said, the Smart table
model is derived from Filtered in concept, and should be a drop-in
replacement for Simple. You will have to adapt your use of filtering to the
different API that Smart offers. The Smart model code is reasonably well
documented, and Fritz Zaucker and I can help you figure out how to use it if
need be.
I can't speak for the QooxDoo team, but my guess is that Smart will
ultimately replace Filtered as there has been almost no activity on Filtered
bug fixes in the past long while... and Smart addresses all the Filtered
issues currently logged in the QooxDoo bugzilla.
Probably not what you wanted to hear, exactly, but that's my advice...
