On the web console, on the Naming subsystem it isn't possible to view or edit simple binding values.

After selecting a simple Binding, for example: /subsystem=naming/binding=java:global/my_parameter, the Data tab on the console remains empty. Also, the following error is generated on the browser console:

2017-01-17 00:52:31,980 [FATAL] Uncaught Exception:
java.lang.IllegalArgumentException: newValue is null

These particular values are configured like this on standalone.xml:

<subsystem xmlns="urn:jboss:domain:naming:2.0">
<bindings>
<simple name="java:global/my_parameter" value="param xpto"/>
</bindings>
</subsystem>
