[CForms/Binding] Exception in form.save(doc) method

[Christofer Dutz <du...@c-ware.de>]

Hi,

 

After using JDom as Dom implementation for my model. I managed to get the
form-binding load my model and I was able to pass it to cocoon as source of
a pipeline. Unfortunately I get a strange exception while calling the forms
save mthod.

 

Here the exception:

 

Internal Server Error

Message: getParent
