[jboss-jira] [JBoss JIRA] (AS7-6235) Reconsider expressions for model reference attributes in server-group and server-config

Brian Stansberry created AS7-6235: ------------------------------------- Summary: Reconsider expressions for model reference attributes in server-group and server-config Key: AS7-6235 URL: https://issues.jboss.org/browse/AS7-6235 Project: Application Server 7 Issue Type: Sub-task Components: Domain Management Reporter: Brian Stansberry Priority: Critical Fix For: 7.2.0.Alpha1 There are some attributes in the server-group and server-config resources that represent references to other resources that support expressions. For example the "group" attribute in a server-config and the "profile" attribute in a server-group. Supporting expressions on such attributes is problematic because it precludes accurately validating that the reference is valid during operation execution Stage.MODEL. This is because expression resolution sources may not be fully populated until Stage.RUNTIME. I wanted to remove expression support from these attributes but was unwilling to do so because of concerns about breaking compatibility. But some recent testing showed me that on *master* for at least some of these, setting an expression would not work -- the HC could not launch servers. If these expressions didn't work *in previous releases* as well, we can remove support for them without breaking compatibility. The task here is to test setting these attributes to expressions in 7.1.2 and 7.1.3. For any attribute like this where expression support didn't actually work, we should remove the support in 7.2. Testing can be done by simply taking the current xml attribute value, e.g. "foo" and using it as the default in an expression, e.g. "${exp-test:foo}" and then starting the HC. There is no need to mess with setting system property "exp-test". -- This message is automatically generated by JIRA.
