[jboss-dev-forums] [Design the new POJO MicroContainer] - Re: Anonymous beans

[bstansberry@jboss.com]

There's a problem with the way the anonymous bean impl (NestedBeanHandler I think) is generating names. Looks like it's getting confused about where it is in the nested bean hierarchy and ends up trying to apply the same name to multiple beans.

The -beans.xml I'm trying to deploy can be found at https://svn.jboss.org/repos/jbossas/trunk/cluster/src/etc/jboss-cache-manager-beans.xml . When I try to deploy it in AS trunk I get this:

Note that the runtimeConfig property is not an immediate child of the CacheConfigurationRegistry bean. It's a property of "StandardSessionCacheConfig" and "FieldSessionCacheConfig".

To add to the challenge, "StandardSessionCacheConfig" and "FieldSessionCacheConfig" really can be anonymous.  I just gave them names for human readability.  So any solution should work even if they were anonymous.

BTW, what I'm trying to do in the part of this file that uses anonymous beans is parse XML to create a set of JBoss Cache configurations. JBC has its own XML format and parser that I can use to accomplish this. It didn't have system property substitution, but I added that earlier this week. So I can use that. I'd prefer to use MC to do this. But don't let me totally rearrange your schedule; I have a workaround.
