I am trying to get functionality that used to work before Prometheus working using the new controls.
Now that we're using the Prometheus RadAjaxPanel and RadContextMenu I get this error at page load:
The Controls collection cannot be modified because the control contains
code blocks (i.e. <% ... %>).
An unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the error and
where it originated in the code.

So my question is.... Is there a workaround to the first problem? If not, is there an alternative solution to the second problem?
Building the context menu using a web service would be ideal, but I pursued that as documented in another thread and never got it to work. I know that behavior wasn't officially supported anyway. Even still, I've lost a week of work trying to get this problem fixed.
Any help would be appreciated.
