Hi Ben, I had similar problems using filters on ArrayCollections and lists. Some really weird rendering issues happened, and I basically manually implemented filters (e.g myCollection.removeAll(), myCollection.addItem( item1 ), myCollection,addItem( item 2)). This played nicely with binding.
I believe I filed bugs against this in 2.0, but I can't fully recall. Did this change at all in 2.0.1 ? Cheers, -D ben.clinkinbeard wrote: > > Hi Dimitrios, > > Thanks for the reply.
