CForms error
When i try to run the forms transforer, I'm getting the following
error. I've checked the input template with xmllint - it's well formed
- here it is:
<?xml version="1.0"?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ft="http://apache.org/cocoon/forms/1.0#template">
<body>
<h1>Edit diary events</h1>
<ft:form-template action="#{$continuation/id}.continue" method="post">

<ft:widget-label id="events"/><br xmlns="http://www.w3.org/1999/xhtml"/>
<ft:repeater-size id="events"/>
<table xmlns="http://www.w3.org/1999/xhtml" border="1">

</tr>
<!-- The contents of the repeater-widget element is a template that will

<ft:repeater-widget id="events">
<tr xmlns="http://www.w3.org/1999/xhtml">
<!-- Don't show the id

-->

<td><ft:widget id="suppression"/></td>
<td><ft:widget id="title"/></td>

</tr>
</ft:repeater-widget>
<tr >
<td colspan="4" align="right">
<ft:widget id="addevent"/>
<ft:widget id="removeevents"/>
</td>
</tr>
</table>
<input xmlns="http://www.w3.org/1999/xhtml" type="submit"/>
</div>
</ft:form-template>
</body>
</html>
So what might be wrong?

Inserting a log transformer between the forms transformer and the
serializer, show it ending thus:
[endElement] uri=http://www.w3.org/1999/xhtml,local=tr,raw=tr
[characters]
[characters]
[comment] The contents of the repeater-widget element is a template that will
be applied to each row in the repeater.
[characters]
[characters]
[startPrefixMapping] prefix=null,uri=null
So it looks to me like a bug in the forms transformer.

Oops - I sent the wrong trace.
That one was saxon failing to transform the output of the forms
transformer.
So I inserted a serialize step after the form transformer, to tae a
look at what is was producing, and I got this:
