Hi John, Thanks for the help. I found the problem.
In my object model, I have the concept of nested templates. In order to support this, I flatten this tree of templates into a list. For each template in the list, I combined them into one big template using the Merge method. But each time I call the Merge method, it evaluates any directives. But because my context is not set yet, the wrong conditional decisions are made. Finally, when I merge the big template with the context, all the conditional directives have been evaluated. This is why I got the strange behavior. Thanks again.
