[jboss-jira] [JBoss JIRA] (AS7-6154) Expression support inconsistency

[Heiko Braun (JIRA)]

     [ https://issues.jboss.org/browse/AS7-6154?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Heiko Braun updated AS7-6154:
-----------------------------

    Description: 
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}
