I used the maven archetype "jboss-javaee6-webapp-blank-archetype" to create a blank project. I have created a messages.properties file as /src/main/java/com.corejsf/messages.properties. In my faces-config.xml, I have configured :

<application>
<resource-bundle>
<base-name>com.corejsf.messages</base-name>
<var>msgs</var>
</resource-bundle>
</application>

Now, when I create a new .xhtml page and want the auto-completion to automatically resolve an expression like #{msgs. i.e after typing #{msgs. when I press CTRL+SPACE, I don't see the list of properties defined in the resource bundle. However, CTRL+SPACE stuff works if I refer to any CDI bean.
