Re: [jboss-dev] generic collection item type
This approach assumes that the component type can be determined with
TypeInfo[] types = typeInfo.getActualTypeArguments();
if (types != null)
elementType = types[0];
This won't work for this class
https://svn.jboss.org/repos/common/jbossxb-builder/trunk/src/test/java/or...
for which its super class should be checked for type arguments and the
component type is the second argument.
I guess I'll need to specify the component type with an annotation. But
it would be nice to have something like Class.getComponentType() to work
for generic collections too.

See generateCollection() here:
http://anonsvn.jboss.org/repos/jbossas/projects/microcontainer/trunk/meta...
which defaults to java.lang.Object if it is not generic.
