Resource Manager is null

[edip]

Hello,
I am building the control tree in code behind and it has not been added to a form or view yet. When i add a control to a container as shown below

                        Ext.Net.AbstractContainer oContainer
                            = ( Ext.Net.AbstractContainer ) parent;

                        Ext.Net.AbstractComponent oChild
                            = ( Ext.Net.AbstractComponent ) 

                        oControl;oContainer.Items.Add ( oChild );

I receive an

Object reference not set to an instance of an object.

error message and the stack trace looks like it getting a property value from the ResourceManager. The stack trace is as follows

at Ext.Net.MVC.MvcResourceManager.get_IsMVC()
at Ext.Net.BaseControl.get_IsMVC()
at Ext.Net.BaseControl.get_SafeResourceManager()
at Ext.Net.BaseControl.get_IsPageSelfRender()
at Ext.Net.BaseControl.EnsureDynamicID()
at Ext.Net.BaseControl.get_ClientID()
at Ext.Net.RadioGroup.AfterItemAdd(Observable item)
at Ext.Net.ItemsCollection`1.Add(T item)

I do not have a ResourceManager since i am loading control dynamically in code behind. Is there anything i can do to avoid this error? Thanks.
