Custom JMX plugin problems

[Al Amyot]

I previously had a simple customized JMX server working which included
an application MBean with %engine% and %port% as dynamic parts of the
name. It successfully discovered the MBean and a couple of metrics.
 
Today, I tried to refine it so that it would discover all the MBeans and
all by replacing a fixed string with the %interaction% variable to the
objectName pattern and the new simple-property element for it. There are
about 15 MBeans matching this pattern. The XML comment below illustrates
a concrete MBean name.
 
Now, the resource is not dynamically discovered so I tried manually
adding it and get this error:
 
There are no connection properties defined for ResourceType[id=10222,
category=Server, name=Initiate JMX server, plugin=Initiate Hub] 
 
(At one point, in error, I changed the plugin name from "Initiate JMX"
to "Initiate Hub". After some work, it nows accepts this new name.)
 
This is the new plugin descriptor. Can anyone suggest what the problen
night be?
