XMLForm problem

[Mark Miller]

Hey all,

| when I use the following simple form:

<?xml version="1.0" encoding="ISO-8859-1"?>

<xf:form xmlns:i18n="http://apache.org/cocoon/i18n/2.1"
xmlns:xf="http://apache.org/cocoon/xmlform/1.0"
id="users-form" view="find-users-result" action="users-form">

<xf:repeat nodeset="results" class="record-table-style">
<xf:output ref="username" class="record-table-style" action-link="edit-user"/>
</xf:repeat>
</xf:form>

I get the following exception (The XMLFormTransformer: class is the same as the cocoon one, but with more debug)


Caused by: java.lang.NullPointerException

It appears as though the URI field in the group attribute is null.
if I change the following line in XMLFormTransform (in unrollRepeatTag):

atts.addAttribute(null, TAG_COMMON_ATTR_REF,
TAG_COMMON_ATTR_REF, "CDATA",
nextNodeLocation);

to 

atts.addAttribute(NS, TAG_COMMON_ATTR_REF,
TAG_COMMON_ATTR_REF, "CDATA",
nextNodeLocation);


it works fine. 

The examples seem to work as is, which I don't get. What am I doing wrong?
