Dynamic XML Datasource in form

[Ian Beaumont]

System:Cocoon 2.1.6

 

I'm looking at the form2simpleXML form flow example, and trying to modify it so that the source document isn't a fixed XML document - but can be generated from another pipeline (in my case it will come from eXist - XML DB).

 

First off - I tried to add a generator in to the sitemap (in this example I'm still using a static doc):

 

     <map:match pattern="form2simpleXML.flow">

       <map:generate src=""/>

       <map:call function="handleForm">
         <map:parameter name="function" value="form2simpleXML"/>
         <map:parameter name="form-definition" value="forms/form2_model.xml"/>
         <map:parameter name="documentURI" value="forms/form2_simple_data.xml"/>
       </map:call>
     </map:match>

but then cannot see how I would change the

binding_example.js call to:

form.loadXML(documentURI);

to use the document from the pipeline.  It also gives about the generator already being set when I try to access the page, so I think this may not me the correct approach.

 

My second solution was to try to use the cocoon protocol as the source of the xml document - so I changed the sitemap as follows:

     <map:match pattern="test.xml">
       <map:generate src=""/>
       <map:serialize type="xml"/>
      </map:match>
    
     <map:match pattern="_form2simpleXML.flow">
       <map:call function="handleForm">
         <map:parameter name="function" value="form2simpleXML"/>
         <map:parameter name="form-definition" value="forms/form2_model.xml"/>
         <map:parameter name="documentURI" value="cocoon:/test.xml"/>
       </map:call>

 

Although this didn't generate any errors - the generated form wasn't pre-populated from the XML.

 

Help!

 

TIA
