Stefan,
Sorry for being slow getting back to you, I was recovering from an illness.
Here are to two stack dumps I promised. I put Thread.dumpStack() in my
implementation of setDynamicAttribute(). The build.xml snippet looks like this:
<parallel>
<java ... /> <!-- start a test server -->
<irongrid module="monitor" ... /> <!-- run our task against it -->
</parallel>
Where <irongrid> is my task. Here is the ant output:
task:
[parallel] Set Dynamic attribute module=monitor
[parallel] java.lang.Exception: Stack trace

yada yada...
You can see I get called twice. Once with the taskname being [parallel] and
once with it being my name, [irongrid].
Is this a bug, or am I supposed to be doing something with maybeCofigure()?
Thanks for your help!
(sending this from a freakin Exchange web-client, hope it doesnt screw up!)

This certainly sounds like a bug. We don't call the attribute setters
or nested creators/storers twice for "normal" elements either.

I think it would, yes.
