I've created my own version of a repeater control that uses

CMSAbstractDataProperties.LoadTransformation(this, Transformation, false);

To load the correct transformation.

This is working nicely but one thing we are seeing is that BizForm expressions are not being parsed correctly. The user entered:

control:BizFormControl?contactForm
(surrounded by 2 percent signs at each side, your forums do process the syntax which is why I can't enter the syntax literally because the post will say "Required form 'contactForm' does not exist." :-)

And it just gets displayed like this on the web page. It seems these are not actually macros, because running CMSContext.CurrentResolved.ResolveMacros on the expression doesn't work either.

My question: what method do I call to make sure the expression gets transformed into an acutal form. Also: where do you recommed calling this method in the ASP.NET lifecyle?
