For the first one, try pointing the source property to the "node" XMLList.
Before it was pointing to an XML datatype.
<mx:XMLListCollection id="xmllcMenu1" source="{xmllMenu1.node}"/>

My short test code is down at the bottom after my description of the
problem.
My object is to populate two mx:Tree objects. In my short code sample
below, only the second tree is getting populated. Can anyone tell me
what I'm doing wrong with the first mx:Tree?
In summary, both mx:Tree objects use XMLListCollection objects as
their dataProviders. Both XMLListCollection objects' sources are
XMLList objects. Both XMLList objects are populated with the same
identical XML data. The only difference is that one XMLList object
gets its XML data from an inline XMLList definition, while the other
is from an inline XML definition which is passed to an XMLList. This
subtle difference causes the first mx:Tree not to show anything, while
the second does. What am I doing wrong?
Thanks in advance.
