In the xml file you need to create the bean, then reference it in the
server element near the top. Other than that...no, that should be all. I
assume you set the Path attribute on the resource.

I thought we were going to do pages/<id>/regions/<id>/regionwidgets/<id>
since it makes no sense to manage a region widget outside a region outside
a page?
