[Xsltforms-support] empty namespace created on submission

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello,

I have a problem that is created due to my need to avoid a server side 
error. This relates to the server declaring invalid any xml that 
contains the same gml:id attribute twice.

As a quick workaround to avoid this problem I can just globally delete 
the gml:id attribute before submission, however this has the effect of 
creating a namespace declaration in the submitted xml as follows:

xmlns:pre3=""

This is also rejected by the server with the message "Prefixed namespace 
bindings may not be empty".

The following xform is a simplified example of what I am doing.

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="xsltforms/xsltforms.xsl" type="text/xsl"?>

            <xf:label>Submit</xf:label>
        </xf:submit>
    </body>
</html>

The xml arriving at the server is as follows:

<Transaction
 xmlns="http://www.opengis.net/wfs"
 xmlns:pre1="http://www.opengis.net/gml"
 xmlns:pre2="http://www.imos.org.au/aatams"
 xmlns:pre3=""
 version="1.1.0"
 service="WFS">
<Insert>
<FeatureCollection>
<pre1:featureMember>
<pre2:device>
<pre2:name>device-1</pre2:name>
<pre2:device_model>
<pre2:device_type>
<pre2:name>RECEIVER</pre2:name>
</pre2:device_type>
</pre2:device_model>
</pre2:device>
</pre1:featureMember>
<pre1:featureMember>
<pre2:device>
<pre2:name>device-2</pre2:name>
<pre2:device_model>
<pre2:device_type>
<pre2:name>RECEIVER</pre2:name>
</pre2:device_type>
</pre2:device_model>
</pre2:device>
</pre1:featureMember>
</FeatureCollection>
</Insert>
</Transaction>

I am hoping that this is a quickly fixed, if not please advise.

Thanks
