It can be set on the server-group.

That means any property that can be inherited will default to UNDEFINED
if set somewhere higher in the tree?

Yes. The model is storing the user's configuration; not any
manipulations we might eventually do.
I can sense a feature request coming...

Feature request? Not yet.
But food for thought.
It is very difficult to work with the current model, because you cannot easily distinguish
the structural information (server-config has a property called 'jvm') from the
actual state (the jvm value is 'default')
Furthermore there is no way to identify inherited properties, or to put it another way:
the inherited state.
Just take the :read-resource outcome as an example.
I would think 'oh, the JVM property is not set'. But actually it is, just at some
other place in tree.
This makes it very hard to work with the current model.
Maybe it would help to introduce a 'reference' value type?
I.e.
{
"jvm" => {ref:<address>}
}
This could actually turn into:
{
"jvm" => {ref:[
"server-group":"default"
]}
}
So you would know that it is an inherited property that's derived from a resource at
<address>
My 2 cents.

/me ponders implications of this idea.
Interesting but has major repurcussions. :-)

I know. At this stage we probably shouldn't introduce major changes.
But then, on the other hand, it might hit us later on.
Think about it, I cannot clearly see all implications.

I'm still a noob when it comes to the domain model but
I just want to reflect Heiko's concerns from a tooling and user perspective -
it seems that for using the http/cli API you not only need to be super aware of these
details;
you also have to do multiple queries to actually resolve the information you as a user,
tools or management console
write would need to get a full picture.
And as far as I can see; you will need to consult that not-yet-existing wiki page
constantly to actually figure out
if a undefined means undefined or inherited (and then where that is inherited from).
I can just imagine the many different implementations that will occur to try and interpret
this lowlevel model ...
management console, jopr, jboss tools, user scripts ....seems to get very error prone very
quickly.
Some way to actually "materialize" the model would be very useful, and possible
even required for sensible external usage IMO.
I believe this were discussed some months ago, but I never saw any real conclusion on it
then.

You mean the ability to configure JVM settings for a host?
I.e. one of these:
[localhost:9999 /] /host=local/jvm=default:read-operation-names
{
"outcome" => "success",
"result" => [
"add",
"add-jvm-option",
"add-system-property",
"read-attribute",
"read-children-names",
"read-children-types",
"read-operation-description",
"read-operation-names",
"read-resource",
"read-resource-description",
"remove",
"remove-jvm-option",
"remove-system-property",
"write-attribute"
],
"compensating-operation" => undefined
}
Don't know. I didn't look into this yet.
