I have tested this in Mono 2.6.7 and it is still occurring.  it occurs when a
second input field in added to a form (via the forms "+" button and happens at
save.  I will attach the code for the page.


The application error is:

Cannot cast from source type to destination type.

Description: HTTP 500. Error processing request.

Stack Trace:

System.InvalidCastException: Cannot cast from source type to destination type.
