TreeCache region configuration

I'm moving from the EHCache provider to the JBoss TreeCache provider as I'm now running in a clustered environment. With EHCache a class would be configured like the following sample:

Code:

    <cache name="com.acme.content.Content"
        maxElementsInMemory="200"
        eternal="false"
        timeToIdleSeconds="86400"
        timeToLiveSeconds="0"
        overflowToDisk="false"
        />
    <cache name="com.acme.content.Content.restrictToRoles"
        maxElementsInMemory="500"
        eternal="false"
        timeToIdleSeconds="86400"
        timeToLiveSeconds="0"
        overflowToDisk="false"
        />

This would cache 'Content' as well as the assocation 'restrictToRoles'.

Using the examples from HIA the region configuration for 'Content' should be something like:

Code:

<region name="/com/acme/content/Content">
   <attribute name="maxNodes">200</attribute>
   <attribute name="timeToLiveSeconds">86400</attribute>
   <attribute name="maxAgeSeconds">0</attribute>
</region>

How though should the assication 'restrictToRoles' be configured? Is the following correct?

Code:

<region name="/com/walkaway/content/Content.restrictToRoles">
   <attribute name="maxNodes">500</attribute>
   <attribute name="timeToLiveSeconds">86400</attribute>
   <attribute name="maxAgeSeconds">0</attribute>
</region>

It appears that the following region configuration might be correct:

Code:

<region name="/com/acme/content/Content/restrictToRoles"> 
   <attribute name="maxNodes">500</attribute> 
   <attribute name="timeToLiveSeconds">86400</attribute> 
   <attribute name="maxAgeSeconds">0</attribute> 
</region> 
<region name="/com/acme/content/Content"> 
   <attribute name="maxNodes">500</attribute> 
   <attribute name="timeToLiveSeconds">86400</attribute> 
   <attribute name="maxAgeSeconds">0</attribute> 
</region> 

This only works if '.../Content/restrictToRoles' is defined before '.../Content'

Could someone verify that this is the correct method of configuring a cached association?

Thanks.
