Hi
I am using tapestry 4 and the latest release of tacos but I am having a few
problems with the updateComponents binding in the AjaxDirectlink. I have
created a component with two nested PartialFor loops and I want to update
the inner PartialFor when the AjaxDirectLink is clicked. Here is the code
and as it is it does work but i am being forced to updated the div
containing the outer loop rather than hust updating the inner loop. Trying
to update that fails.
A bit of background, the persistent layer is Cayenne (latest release) and
all the objects are persistent.
.html
<div jwcid="structuralPublishItemsArea" id="structuralPublishItemsArea">
<span jwcid="@If" condition="ognl:structuralNode">
<div style="padding-bottom:10px;font-size:10pt;font-weight:bold;"><span
jwcid="@Insert" value="ognl:structuralNode.structuralPath" /></div>
<span jwcid="foreachPublishItem">
<div jwcid="publishItemName"
id="ognl:structuralPublishItem.name">
<span jwcid="publishItemLink">
<span jwcid="@Insert"
value="ognl:structuralPublishItem.name" />
</span>
<span jwcid="@If"
condition="ognl:isPublishItemSelected">
<span
jwcid="foreachPublishItemKeyValue">
<div jwcid="@Any"
class="ognl:beans.evenOdd.next">
<span jwcid="@Insert"
value="ognl:structuralPersistentKey" />
<span jwcid="@Insert"
value="ognl:structuralPublishItem.mergedDictionary.get(structuralPersistentKey)"
/>
</div>
</span>
</span>
</div>

</div>

<inject property="listenerInvoker"
object="infrastructure:listenerInvoker"/>
<inject property="ajaxWebRequest"
object="service:tacos.AjaxWebRequest"/>

What is the difference between updateComponents and updateBlocks? What am I
doing wrong here. Please let me know if you need more information or if any
of this in unclear.
