             Summary: Revisit how the model validation happens
                 Key: WFLY-4346
                 URL: https://issues.jboss.org/browse/WFLY-4346
             Project: WildFly
          Issue Type: Feature Request
          Components: Domain Management
            Reporter: Kabir Khan
            Assignee: Brian Stansberry
             Fix For: 9.0.0.Beta1


Currently the ValidateModelStepHandler is triggered by AbstractAddStepHandler, and does not seem to be triggered for writes.

Also if used in a composite along the lines of
{code}
[standalone at localhost:9990 /] batch
[standalone at localhost:9990 / #] /system-property=xxx:add(value=test)
[standalone at localhost:9990 / #] /system-property=xxx:remove
[standalone at localhost:9990 / #] run-batch 
{code}
the handler will get triggered at the end for the add. It will fail for the add since there is no such resource. While that is easy to work around by checking for a NoSuchResourceException around the OC.readResource() it seems that what triggers the use of the ValidateModelStepHandler should be more an intrinsic part of the controller which knows what has and has not been added/removed/written to.
