Subject Woody : binding
Date Fri, 31 Oct 2003 17:18:14 GMT
Hi all !

I have a problem concerning the binding in woody :

I have repeater bound with following structure :
<person id="">
   <person_id>156</person_id>
   <person_data>some data</person_data>
</person>
<person id="">
   <person_id>157</person_id>
   <person_data>other data</person_data>
</person>
...

here is the repeater binding :
<wb:repeater id="persons" parent-path="." row-path="person" unique-row-id="id" 
unique-path="@id">
   <wb:on-bind>
     <wb:value id="person_id" path="person_id" />
     <wb:value id="person_data" path="person_data" />
   </wb:on-bind>

   <wb:on-delete-row>
     <wb:delete-node />
    </wb:on-delete-row>
		
   <wb:on-insert-row>
     <wb:insert-node>
       <person id="">
         <person_id />
         <person_data />
       </person>
     </wb:insert-node>
   </wb:on-insert-row>
</wb:repeater>


and the container :

<wd:repeater id="persons">
   <wd:output id="id">
     <wd:datatype base="string"/>
   </wd:output>
   <wd:field id="person_id">
     <wd:label>ID</wd:label>
     <wd:datatype base="string"/>
   </wd:field>
   <wd:field id="person_data">
     <wd:datatype base="string"/>
   </wd:field>
</wd:repeater>	


Obviously, @id and person_id play the same role, but this is the only way I get it work. 
When I set :

 >>row-path="person_id" unique-row-id="person_id"<<
on the repeater binding, the last row added is equals to the same...

and when I bind the widget person_id to @id :
 >>
   <wb:on-bind>
     <wb:value id="person_id" path="@id" />
     <wb:value id="person_data" path="person_data" />
   </wb:on-bind>
<<
I have a JXPath exception, telling that the value cannot be bound with @id...

What is wrong ?
  - is "@id" a wrong JXPath expression ? If yes, how can I bound the person_id widget with

the person/@id in the structure ?
  - are the attrs of the repeater binding >>row-path="person_id" 
unique-row-id="person_id"<< wrong ? In this case, what is the true syntax ?

Thanks in advance, and more if you read this mail until the end :) ...
