Hello,
I am trying to understand the process and minimum requirement for setting up a simple CForm in Cocoon 2.1.5. I have followed the doco and samples where possible but I think I've hit a wall. I have created a simple form, but failed when binding from an XML file with the following error:
org.mozilla.javascript.EvaluatorException: "resource://org/apache/cocoon/forms/flow/javascript/Form.js", line 164: Invalid JavaScript value of type org.mozilla.javascript.UniqueTag
I reduced the form down to a simple single text field bind, but still received the same error.
What I have set up is a simple form called batchUpload with its own dir area as follows:
BASEDIR: cocoon2.1.5/build/webapp/forms-test
Forms: $BASEDIR/forms
Flow: $BASEDIR/flow
Resources: $BASEDIR/resources (this is a copy of the cocoon resources dir build/webapp/samples/blocks/forms/resources, so has the field stylesheets, etc)
Messages: $BASEDIR/messages
Sitemap: $BASEDIR/sitemap.xmap
The sitemap file is as follows:
<?xml version="1.0"?>
<map:sitemap xmlns:map="http://apache.org/cocoon/sitemap/1.0";>
<map:components>
<map:transformers default="xalan">

=====================
The Javascript to do the form load (batchUpload.js), bind and display is as follows (within the form.load() is where the exception mentioned above is thrown)
cocoon.load("resource://org/apache/cocoon/forms/flow/javascript/Form.js");function batchUpload() {
var form = new Form("forms/batchUpload.xml");
// added for bind
var documentURI = cocoon.parameters["documentURI"];// parse the document to a DOM-tree var document = loadDocument(documentURI);
// bind the document data to the form form.load(document);
// The showForm function will keep redisplaying the form until
// everything is valid
form.showForm("batchUpload-display-pipeline");
}function loadDocument(uri) {
var parser = null;
var source = null;
var resolver = null;
try {
parser = cocoon.getComponent(Packages.org.apache.excalibur.xml.dom.DOMParser.ROLE);
resolver = cocoon.getComponent(Packages.org.apache.cocoon.environment.SourceResolver.ROLE);
source = resolver.resolveURI(uri);
var is = new Packages.org.xml.sax.InputSource(source.getInputStream());
is.setSystemId(source.getURI());
return parser.parseDocument(is);
} finally {
if (source != null)
resolver.release(source);
cocoon.releaseComponent(parser);
cocoon.releaseComponent(resolver);
}
}
============
The binding file (batchUpload_bind.xml) is the simplified bding file:
<?xml version="1.0"?>
<fb:context xmlns:fb="http://apache.org/cocoon/forms/1.0#binding"; path="/" direction="load" xmlns:fd="http://apache.org/cocoon/forms/1.0#definition";>
<fb:value id="bitstreamDirSelect" path="/dc-elements/dc-element1"/>
</fb:context>
==============
The simplified data file (batchUpload_data.xml) is as follows:
<?xml version="1.0"?> <dc-elements> <dc-element1 qualified="true">subject.other</dc-element1> </dc-elements>
===================
The form definition (batchUpload.xml) is as follows:

Finally, the template file (batchUpload_template.xml) is as follows:
