[jboss-user] [JBoss Seam] - Configuring POJOs as Seam Components in components.xml

[youngm]

I'm using 1.2.0.nightly

Is it legal to configure POJOs as Seam components in components.xml?

For example:
<component name="expanderState" class="java.util.HashMap" auto-create="true" scope="conversation"/>

I get:
