RE: CForm Bind problem (EvaluatorException: org.mozilla.javascript.UniqueTag)

[Michael Ralston]

I'm having a problem creating a CForm with repeaters and binding it to an XML 
document. I found Scott's email on the mailing list last year (June 22, 2004) 
with a similar error and I'm wondering if anyone else has had the error and 
found a solution.

I have based my code on the sample in cocoon, with the following files...
 - form2_model.xml
 - form2_bind_xml.xml
 - form2_template.xml

specifically I was looking at the 'contacts' widget in those files.

This is my error...
org.mozilla.javascript.EvaluatorException: 
"resource://org/apache/cocoon/forms/flow/javascript/Form.js", line 183: 
Invalid JavaScript value of type org.mozilla.javascript.UniqueTag

Below are my xml files.

Thanks
