Hi Peter,
To get namespaces to bind in 2.1.8 i found you need to set
namespace-prefixes to true for the xml-parser in your cocoon.xconf
file. 2.1.8 also has some bugs in the repeater binding which prevents
the propagation of namespaces in the binding file.
See : http://issues.apache.org/jira/browse/COCOON-1671
Regards,
Suzan Foster.

Hi,
we are using Cocoon 2.1.8 and have a form for creating a new object.
That means there is no data loaded into the form but only saved from
the
form to a XML document.
The binding using a binding file uses XML namespaces, which seems to be
the only difference to some of the samples, where one (dynamic
repeater)
also creates a new document and then only saves the form.
The problem that we get is
Caused by: org.apache.commons.jxpath.JXPathException: Exception trying

Also the method of previously loading a existing empty or full XML
document and trying to save to this does not work with even worse
exceptions.
I can't but assume that the reason is namespaces because the sample
does
exactly the same as we do and does work.
flow script function:
---
function newPolicy()
{
var definitionURI = cocoon.parameters["newDefinitionURI"];
var bindingURI = cocoon.parameters["newBindingURI"];
var form = new Form(definitionURI);
form.createBinding(bindingURI);
form.showForm("newPolicy-display");
var policy =
Packages.javax.xml.parsers.DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
var policy = factory.newDocumentBuilder().newDocument();
//policy.appendChild(policy.createElementNS("http://blue-elephant-
systems.com/midas/ovo/1.0",
"ovo:policy"));
// var policy = loadDocument("logfile.xml");
// get the basic policy from the form
form.save(policy);
// just for debugging
saveDocument(policy, "output.xml");
// go into edit phase
form = getPolicyForm(policy);
cocoon.request.setAttribute("formMode", "edit");
form.showForm("editPolicy-display");
form.save(policy);
saveDocument(policy, "output.xml");
}

sample simple binding
---

any idea what one could do to get this to work?
Thanks, Peter
