Description

This is about finding the correct location to place a hidden field to store the t:formdata for the Zone.

java.lang.IllegalStateException
The rendered content did not include any elements that allow for the positioning of the hidden form field's element.

I believe that it should create the hidden field directly inside the Zone, or possibly create a <div> inside the Zone to contain the necessary hidden field.

A workaround is to provide a <div> somewhere inside the rendered content.
