dragSupport usage... help!

[epesh]

I have a datalist in one table, and a scrollable datatable in another... and I'm trying to get it so that I can drag the rows from the scrollable datatable to the datalist. I keep getting a message:

element [foo:bar] ID was not found in the DOM tree.

WTF... where do I put this? The examples don't show me what I'm supposed to do here. Any help?

Section 1:

<h:outputLabel for="authors">
<rich:dropSupport reRender="authors" dropListener="#{addarticlebean.authorDropListener}"
acceptedTypes="author">
<h:outputText value="Authors:"/>
</rich:dropSupport>
</h:outputLabel>
<rich:dataList id="authors" binding="#{addarticlebean.authors}"/>
<h:message for="authors"/>

Section 2:

<rich:scrollableDataTable var="author" value="#{addarticlebean.authorList}">
<rich:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<a4j:outputPanel>
<rich:dragSupport dragType="author">
<rich:dndParam name="authorid" value="#{author.id}"/>
</rich:dragSupport>
<h:outputText value="#{author.lastname}"/>,
<h:outputText value="#{author.firstname}"/>
</a4j:outputPanel>
</rich:column>
</rich:scrollableDataTable>

I wouldn't be surprised if this was a MESS -- after all, this is me trying to figure out what the heck I'm doing.
