I have not been able to pin down what the specific issue is yet, as the error is worthless, and generated in an inaccessible method in the Page. I assume it is having trouble locating the HtmlTextArea from the loaded control(s), but I will have to build and instrument Mono itself to have a clue where and why. Ugh.
