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

[Christofer Dutz]

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   Description: org.apache.avalon.framework.CascadingRuntimeException: uncaught _javascript_ exception: at showCart (file:/D:/home/domains/127.0.0.1/shop/flows/cwebShopLite.js, Line 165) at (resource://org/apache/cocoon/forms/flow/_javascript_/Form.js, Line 190): org.apache.commons.jxpath.JXPathException: Exception trying to remove all for xpath product;
