[Mono-dev] Controls within a control in ASP.NET

I'm currently using ASP.NET controls from ComponentArt for my ASP.NET applications since the ComponentArt DLL is fully compatible with Mono (except for one function).
Now, everything works fine in my apps using the ComponentArt controls (such as treeviews, buttons, etc.) but now the problem is this:
One of the ComponentArt controls is a Dialog Box control that encapsulates other controls within it (like buttons, tables, text boxes, etc.) The minute I add a dialog control to my page and then put some other controls inside it, I start getting the following error:
Object reference not set to an instance of an object
Description: HTTP 500. Error processing request.
System.NullReferenceException: Object reference not set to an instance of an object
at ASP.default_aspx.__BuildControl__bctrl_4 (ComponentArt.Web.UI.DialogContent __ctrl) [0x00000]

at System.Web.HttpApplication+<Pipeline>c__Iterator5.MoveNext () [0x00000]
at System.Web.HttpApplication.Tick () [0x00000]
Version information: Mono Version: 2.0.50727.42; ASP.NET Version: 2.0.50727.42
Now, it obviously works with Windows just fine, but when I tested it in XSP2 (Mono v2.0 Preview) or on my Linux box (OpenSUSE with Mono 1.9.1) I get the errors above. I'm not sure where to go from here.
Any ideas? Or are there any workarounds? Any help would be great!
