Hi Andrew and other AJAX experts,
I got a slower day so I tried to get AA to work with my tree2. I first created
a tld for your aaTree tag. Then I updated my jsp file to use the tag. The
tree loads fine. But I am getting a javascript error now in a pop up box when
I try to expand a tree node. The error message is "AjaxAnywhere default error
handler. XMLHttpRequest HTTP Error code:404 Would you like to view the
response content in a new window?"
I don't think the request is sent to the backend. Have you had any similar
issues when you use AA? Is there any way to debug this to get more information?
Thanks a lot for your help,
Jane
BTW, My jsf page looks like this
</script>
</t:documentHead>
<t:documentBody>
<h:form id="cdeBrowserTree">
<h:commandLink value="Refresh tree"
action="#{treeBacker.refreshTree}"/>
<br/>
<br/>
<!-- Expand/Collapse Handled By Server -->
<aa:zoneJSF id="treeZone">
<jcaa:aaTree id="cdeBrowserTree" value="#{treeBacker.treeModel}"
ajaxZone="treeZone"
var="node" varNodeToggler="t" clientSideToggle="false"
binding="#{treeBacker.tree}">
<f:facet name="Context Folder">
....
</f:facet>
</jcaa:aaTree>
</aa:zoneJSF>
</h:form>
<script type="text/javascript">
ajaxAnywhere.getZonesToReload = function(url, submitButton) {
return "treeZone"
}
ajaxAnywhere.formName = "cdeBrowserTree";
ajaxAnywhere.bindById();
ajaxAnywhere.substituteFormSubmitFunction();
ajaxAnywhere.substituteSubmitButtons();
</script>
</t:documentBody>
</t:document>
</f:view>

I tried to google on the tag library. I could not find an all in one guide.
The old ones are tlds in JSP, new ones on facelet and taglib.xml. I never find
out if they are suppose to work together. I only know that I could not find
tlds for Tomahawk tag libraries. But they work in my environment. So it seems
like there must be a way to use the taglib.xml.
The AA tags do come with TLD.
I will write a TLD and see if that works. Please let me know if you have a
better way to get around it.
Thanks,
Jane

Shoot, I forgot the JSP needs TLD files, I never wrote one, as I was
thinking in "pure" JSF terms.
