Grid & RDF

Hi all...
I have an RDF like this:

    <RDF:Description RDF:about="http://www.someldap.com/AREA">
         <ATTRIBUTE:dn>AREA100</ATTRIBUTE:dn>
         <ATTRIBUTE:complete>dc=AREA100</ATTRIBUTE:complete>
         <ATTRIBUTE:about>http://www.someldap.com/AREA100</ATTRIBUTE:about>
         <ATTRIBUTE:name>dc</ATTRIBUTE:name>
         <ATTRIBUTE:value>AREA100</ATTRIBUTE:value>
     </RDF:Description>
     <RDF:Description RDF:about="http://www.someldap.com/AREA/Company">
         <ATTRIBUTE:dn>COMPANY</ATTRIBUTE:dn>

     </RDF:Description>
     .....

     <RDF:Seq RDF:about="http://www.someldap.com/all-entries">
         <RDF:li>

                             <RDF:Seq 
RDF:about="http://www.someldap.com/AREA/Company/Group">
                                     <RDF:li 
RDF:resource="http://www.someldap.com/AREA/Company/Group/User"/>
                                     <RDF:li 
RDF:resource="http://www.someldap.com/AREA/Company/Group/User1"/>
                                     <RDF:li 
RDF:resource="http://www.someldap.com/AREA/Company/Group/User2"/>
                                     <RDF:li 
RDF:resource="http://www.someldap.com/AREA/Company/Group/User3"/>
                             </RDF:Seq>
	.....

If I use this RDF to display a tree and all works correctly.
Now, I want to use it to display the data of a tree entry and I use a 
grid like this.
	....
	<grid id="detailsGrid" width="250" height="350">
		<columns>
			<column flex="1"/>
			<column flex="1"/>
		</columns>
		<rows id="detailsRows" datasources="myRdf.rdf" 
ref="http://www.someldap.com/all-entries">
			<template>
				<rule>
					<row uri="rdf:*">
						<label flex="1" value="rdf:http://www.someldap.com/rdf#name"/>
						<textbox flex="1" value="rdf:http://www.someldap.com/rdf#value"/>
					</row>
				</rule>
			</template>
		</rows>
	</grid>
	....
Since my RDF is remote I set datasources and ref of element rows by 
javascript.
If I set ref to "http://www.someldap.com/AREA/Company/Group" I see all 
cn of users.
If I set ref to one of the users I don't see anything.
Why?
