ServerControl, Collection editor issue

[KK]

Hi

I have created a collection editor for my server control.
Collection eidtor works fine, I can add/remove my ObjectTypes
and manipulate properties of ObjectTypes.

My ObjectType control have a property named Value. it is
decorated with [Bindable(true)] However, in collection
editor, if I click the Databinding [...] button it craches
giving a null reference issue.

What is the cause of it? I want it to open the binding
window (as in windows forms) So I can type the
binding expression for the Value property.

Any help is appreciated

Regards
KK
