I trimmed my source down to the simplest form trying to isolate the issue. I
pasted in the simplest form I could get to. My original contains a number
of elements including a bean edit form:
<t:submitnotifier>
<div t:type="beaneditor" t:id="currentcomparison" />
<t:removerowlink>Remove</t:removerowlink>
</t:submitnotifier>
It yields the same exception. There were many more elements in there when
the exception was first thrown. Tried to trim out any mistake I might be
making and was left with the most basic AjaxFormLoop.
