Subject Re: T4: Parameter 'anchor' is not bound and can not be updated
Date Thu, 01 Sep 2005 13:11:56 GMT
I'm wondering if setting an unbound parameter programmatically in T4 should 
be similar to the way that the IComponentVisitor classes do it, by manually 
creating a binding and setting that. I suppose I could try that...
