How can I get control's owner from tpProperties in universal way? This control can be included in different pages inside of different elements, and I need to get, for example, owner's height. In Ext.1 tpProperties.ownerCt worked fine, but in version 2 not the same.

OK, the problem is more complex.
I test 2 different pages. In first, more complex, this not works (tpProperties not have "ownerCt" property in general), but in second everything works fine.
How can I find, what is wrong?
By the way, at this complex page not fires doLayout after load (resulting representation is broken until I manually call doLayout of container or resize browser window).
What are ways to locate and fix these problems? Should I post whole page markup to get some help?

ownerCt problem fixed by adding Layout to control's container.
