.net in XControl

[Artem.SPb]

I'm doing a wrapper for .Net library.
Without X-control, everything works, here it is necessary to do the following:

There is a client and a widget. After the connection, you need to register a callback.
Such a scheme works.

I want to hide the ref in the X-control so that there are no .Net references outside .
I have a control on the front and I save the link in each cluster in the cluster:

Connect maked as a separate method

but when I call it, the link WFWidget is zero.
All other variables are successfully saved, but the link to the widget is lost.
How to save a link in Display State In cluster and use outside of facade?

When you save a ref to the state cluster, you need to set the flag "state changed?", then everything works.
