Setting values in XMLForm (via JXPath)

[Christopher Oliver]

It appears that XMLForm's use of JXPath is hardcoded to setting indexed 
values only on Java arrays and Collections (not DOM nodes or other types 
of JXPath nodes). I was attempting to use a JavaScript object as a 
JXPath node, but ran into the below problem in Form.java 
(http://cvs.apache.org/viewcvs.cgi/*checkout*/xml-cocoon2/src/java/org/apache/cocoon/components/xmlform/Form.java?rev=HEAD&content-type=text/plain)

Dmitri, what is the proper way to set collection values in JXPath? 
Should we be using createPathAndSetValue() here?

Regards,

Chris

               //    // (like in the selectMany case),
               //    // iterate over the array and set individual values
               //    if ( values.length > 1  )
               //    {
               //      Iterator iter = 
jxcontext_.iteratePointers(xpath);     
               //      for (int i = 0; i < values.length; i++ )
               //      {

                       cl.clear();
                       cl.addAll(java.util.Arrays.asList(values));
               }
               // otherwise set the value of the first element
               // (and the only) from the values array
