Hi All

I am trying to get an aggregated field to work as part of a 
repeater-row.

Does anyone know if these work?
I get no <wi:value/> in the 'reference' widget.

model:

<wd:form
   xmlns:wd="http://apache.org/cocoon/woody/definition/1.0"
   xmlns:i18n="http://apache.org/cocoon/i18n/2.1">
   <wd:widgets>
     . . .
     <wd:repeater id="resources">
       <wd:widgets>
        . . .
       <wd:aggregatefield id="reference" required="true">
         <wd:label><i18n:text 
i18n:catalogue="local">label.artefact</i18n:text></wd:label>
         <wd:split pattern="([0-9]*)/([0-9]*)">
          <wd:map group="1" field="artefact"/>
          <wd:map group="2" field="image"/>
         </wd:split>
         <wd:combine expression='Concat(artefact, "/", image)'/>
         <wd:widgets>
          <wd:field id="artefact"><wd:datatype base="string"/></wd:field>
          <wd:field id="image"><wd:datatype base="string"/></wd:field>
         </wd:widgets>
        </wd:aggregatefield>
       </wd:widgets>
       . . .
     </wd:repeater>
     . . .
   </wd:widgets>
</wd:form>

binding:

<wb:context xmlns:wb="http://apache.org/cocoon/woody/binding/1.0" 
path="/" >
   . . .
   <wb:repeater id="resources"
     parent-path="."
     row-path="resources"
     unique-row-id="sid"
     unique-path="sid">
     <wb:on-bind>
       . . .
       <wb:aggregate id="reference" path="." >
         <wb:value id="artefact" path="artefact"/>
         <wb:value id="image" path="image"/>
       </wb:aggregate>
       . . .
     </wb:on-bind>
     . . .
   </wb:repeater>
</wb:context>

Thanks for any suggestions

regards Jeremy
