[ https://issues.jboss.org/browse/AS7-2139?page=com.atlassian.jira.plugin.s... ] Brian Stansberry resolved AS7-2139. ----------------------------------- Fix Version/s: 7.1.0.Beta1 (was: 7.1.0.CR1) Resolution: Done On the root resource for a server, or on the /host=xxx resource for a HostController, to get the value for an expression *on that process*, use :resolve-expression(expression=${the.expression}) To get the value on every server in the domain, on the root resource on the master host controller (the DC), use :resolve-expression-on-domain(expression=${the.expression}) To get the value on every server managed by a given host, on the /host=xxx resource, use :resolve-expression-on-domain(expression=${the.expression}) The value for xxx in expression=xxx can be any text that can be converted to a DMR string. (So no DMR lists or objects). So these will work :resolve-expression(expression=hello) :resolve-expression(expression=10) :resolve-expression The first two result in a return value of ModelType.STRING that is the string form of what was passed in. (The return type of the operation is always STRING.) The last one will result in a return value of ModelType.UNDEFINED. Basically, the server will take the passed in value and see if it's ModelType.EXPRESSION. If not it will convert it to a string and try to parse that string into a node of type EXPRESSION. If it's not expression syntax it will become a node of type STRING. It will then resolve that node and will pass back the result. When I merge a jboss-dmr patch Scott Stark has submitted, the ModelNode.resolve() operation will start throwing an exception if the value is ModelType.EXPRESSION and the expression cannot be resolved. Once I merge that, these operations will return a failure if an expression cannot be resolved. Passing in a non-expression value will still work as above; that isn't considered a failure. -- This message is automatically generated by JIRA.
