java - Wildfly 8.2/Undertow - properties placeholder does not seem to work for alias attribute in host configuration -

i'm trying generalize wildfly (8.2 final) xml configuration in order have single configuration xml file references of system properties (${what.ever.value.key.from.proerties}) in order distinguish dev. , prod. env. different .properties-files.

worked fine till i've rich undertow subsystem. when try reference value property alias attribute of vertual host configuration - doesn't seem recognize , resolve @ position key value .properties.

a small snippet of wildfly xml configuration show mean exactly:

<subsystem xmlns="urn:jboss:domain:undertow:1.2">     ...     <server name="default-server">         ...         <host name="default-host" alias="${undertow.virtual.host.alias.mydomain}">             ...         </host>     </server>     ... </subsystem> 

and corresponding entries in dev.properties file:

undertow.virtual.host.alias.mydomain=localhost 

and in prod.properties file:

undertow.virtual.host.alias.mydomain=www.mydomain.com 

the value of key 'undertow.virtual.host.alias.mydomain' not substituted. do wrong here? or such functionality not support alias attribute?

thanks in advance!

that attribute doesn't:

"alias" => {     "type" => list,     "description" => "aliases host",     "expressions-allowed" => false,     "nillable" => true,     "value-type" => string,     "access-type" => "read-write",     "storage" => "configuration",     "restart-required" => "all-services" } 

you can use read-resource-description operation see if expressions allowed. example /subsystem=undertow/server=default-server/host=default-host:read-resource-description resource.

you @ wildscribe site should have versions available.
