Re: [jboss-as7-dev] Level for add operations

For the threads subsystem I register a description provider at

ADD_THREAD_FACTORY operation which implements ModelAddOperationHandler. I can then invoke
that operation for the address profile => test => subsystem => threads to add
a ThreadFactory. However, if I add more than one ThreadFactory, the last overwrites the
previous, meaning I can only have one ThreadFactory.
What I originally had in mind was to register this add handler at profile => test
=> subsystem => threads => threadfactory => * , but when I try to invoke
the operation for the address profile => test => subsystem => threads =>
threadfactory => threadfactoryA it fails since the model controller does not find the
operation since that node does not exist yet (that node is what I am trying to add)
This approach is what's intended; I'll think a bit about what the
problem is.
So, in a nutshell, I am unsure how to properly handle add
operations.
Also, when parsing the xml into add operations I need the address that the add operation
should apply to, where can I get that? At the moment I am just hard-coding it
The parent address should be parsed into the parsing method. The parser
creates the operation address as follows:
Option A)
op.get(OP_ADDR).set(parentAddress).add("childtype", name);
Option B) -- if you need a ref to the new address
ModelNode address = parentAddress.clone().add("childtype", name);
op.get(OP_ADDR).set(address);
In Option A the set() call copies parentAddress, so it's safe to mutate
it via the add().
