Inconsistent expression support ------------------------------- Key: AS7-6154 URL: https://issues.jboss.org/browse/AS7-6154 Project: Application Server 7 Issue Type: Feature Request Components: Domain Management Reporter: Heiko Braun Assignee: Stefano Maestri Fix For: 7.2.0.CR1 Although some subsystem declare support for expression on certain attributes, they actually don't support it. As en example see datasources > pool > max-pool-size. The DMR description says it supports expressions on this attribute: {noformat} "max-pool-size" => { "type" => INT, "description" => "The max-pool-size element specifies the maximum number of connections for a pool. No more connections will be created in each sub-pool", "expressions-allowed" => true, "nillable" => true, "default" => 20, "access-type" => "read-write", "storage" => "configuration", "restart-required" => "no-services" }, {noformat} But then writing an expression value yields an exception {noformat} Request [ERROR] { [ERROR] "operation" => "composite", [ERROR] "address" => [], [ERROR] "steps" => [{ [ERROR] "address" => [ [ERROR] ("profile" => "full"), [ERROR] ("subsystem" => "datasources"), [ERROR] ("data-source" => "ExampleDS") [ERROR] ], [ERROR] "operation" => "write-attribute", [ERROR] "name" => "max-pool-size", [ERROR] "value" => expression "${pool:15}" [ERROR] }] [ERROR] } {noformat} {noformat} 08:48:23,965 DEBUG [org.jboss.as.controller.management-operation] (HttpManagementService-threads - 5) JBAS014616: Operation ("write-attribute") failed - address: ([ ("subsystem" => "datasources"), ("data-source" => "ExampleDS") ]) - failure description: "JBAS014688: Wrong type for value. Expected [INT] but was EXPRESSION" {noformat}
