[Xsltforms-support] attribute namespace problem

[Stephen C. <Ste...@ut...>]

Hello

I am getting an error in Firefox with an XPath having an predicate 
containing an attribute with a namespace.

This is the code in question:

        <xf:select1 bind="project_role_person" appearance="minimal" 
incremental="true()">
            <xf:label>Person</xf:label>
            <xf:item>
               <xf:label/>
               <xf:value/>
            </xf:item>
        <xf:itemset 
nodeset="instance('inst_project_role_person')//aatams:project_role_person[aatams:project_ref/aatams:project/@gml:id=instance('inst_prp')/project_id]">
               <xf:value ref="@gml:id"/>
           <xf:label ref="aatams:person_ref/aatams:person/aatams:name"/>
            </xf:itemset>
            <xf:help>This is a presently unhelpful help message</xf:help>
         </xf:select1>

The problem sees to be the use of @gml:id, the error I see is:

Error: XForms Error (10): Error parsing XPath expression: 
instance('inst_project_role_person')//aatams:project_role_person[aatams:project_ref/aatams:project/@gml:id=instance('inst_prp')/project_id]

Elsewhere the same use of @gml:id is not causing a problem so I suspect 
it is an issue with the select1 implementation only.

For example the code below works in my submit, which is doing exactly 
the same thing (I think).

               <xf:insert 
nodeset="instance('inst_data')//aatams:model_ref/aatams:device_model"
                          
origin="instance('inst_device_model')//aatams:device_model[@gml:id=instance('inst_subfeatures')/device_model_id]"/>

The one difference is that the select1 nodeset XPath will not find any 
nodes on loading the form as the value "instance('inst_prp')/project_id" 
has not been set by the user from another select1.

I'd really appreciate some assistance in getting this resolved as it is 
a final hurdle before my app. can be used in production.

Thanks
