CFORM XML bind only works with file resource. Cocoon 2.19

[Manuel Ottaviano <co...@lst.tfo.upm.es>]

*Hello cocoon world.
I'm using the 2.19 version of Cocoon. I'm developing some CFROM using 
the example included in the framework.
I'm using the example "samples/blocks/forms/form2simpleXML.flow"   as 
starting point.
The example works fine with a binding file , but if I substitute the 
file with a cocoon resource as follow:*

<map:match pattern="form2simpleXML.flow">
      <map:call function="handleForm">
        <map:parameter name="function" value="form2simpleXML"/>
        <map:parameter name="definitionURI" value="forms/form2_model.xml"/>
        <!-- <map:parameter name="documentURI" 
value="forms/form2_simple_data.xml"/> -->  
        <map:parameter name="documentURI" 
value="cocoon:/forms/form2_simple_data.xml"/> 
      </map:call>
    </map:match>
       <map:match pattern="forms/form2_simple_data.xml">
      <map:generate src="forms/form2_simple_data.xml"/>
      <map:serialize type="xml" />
    </map:match>


*Cocoon generates an error : *
org.mozilla.javascript.EvaluatorException: 
"resource://org/apache/cocoon/forms/flow/javascript/Form.js", line 285: 
The choice of Java method 
org.apache.cocoon.components.source.SourceUtil.toSAX matching JavaScript 
argument types 
(org.apache.cocoon.components.source.impl.SitemapSource,org.apache.cocoon.forms.util.XMLAdapter)

*Looking in the web I've found the same  bug of the current development 
version of Cocoon. The article is below:*

http://issues.apache.org/jira/browse/COCOON-1906

*I've patched my verson of cocoon but it does not solve the problem.....
Why??*
