SP9 : instance of view not found

[Former Member]

Hi,

I am seeing the following issue with service stack 9.

Scenario

Component A references view and interface controller of component B.

Subscribe to server event from Interface controller B to A.

Component A launches view of component B in a WDWindow.

Component B fires server event on interface controller B.

Component B calls destroy() on the window.

Component A receives data on server event on B.

Problem.

The first time this code is executed, there are no problems. It is only the second time that we run into a the exception below.

The code works like a dream in SP4.

It is 100% reproducible inside the Enterprise Portal SP9.

We unsubscribe to all portal events before view navigation.

The exception immediately after the event listener for server event B is invoked.

Any ideas what causes this?
