The Push Server's logic was incorrect. Basically, the following happened:
1. There's an outstanding blocking receive-updated-views request to the Push Server for ICEfaces application 1 with ICEfaces ID 1.
2. A new tab is opened to ICEfaces application 2 with ICEfaces ID 2.
3. A new blocking receive-updated-views request to the Push Server is issued but now with ICEfaces IDs 1 and 2.
4. Due to incorrect logic the previous blocking receive-updated-views request with ICEfaces ID 1 is not unblocked.
When 3. occurs, any outstanding blocking receive-updated-views request with an ICEfaces ID contained in the new blocking receive-updated-views request should be unblocked.
The improved logic is in place. Marking this one as FIXED.
Changed Fix Version(s) to 1.8.0
