Connector can only be initialized for an attached Grid error when switching between routes

[nbabb]

It seems that the first page we load (with a disabled AbstractCompositeField that contains a Grid) works fine, but when we navigate away from this page to another page the error is thrown. When doing the same thing in the live application it does not appear to be an issue.

Seems the call to getUI() is returning null in the case where we are navigating away from a page with a disabled Grid contained by an AbstractCompositeField.

Stacktrace is

Hi, thank you for letting me know. The test case is a bit complex; could you please post a simple test code which reproduces the issue?
