I am using the rbf_setLookupFilter api to filter contacts related to my account in the new UI. The filter seems to be setting itself appropriately when the value of my account is changed. If I use the search window, my results are appropriately filtered to the contacts related to that account.
However, when I just start typing in the name of one of the contacts related to that account, the values being matched are from other accounts as well. 
I would have expected it only to return the values that matched that were also filtered the account selected. Is this a known issue and if so, can you tell me when you expect it to be fixed?
Hi Jason,
All the lookup field filter related issues have been resolved in 4.0.4 which is due for release this weekend.
