Ok i figured that.

Ah yes. Just after I'd sent the email I found the JavaPluginConfig, which
I've now used. I gave the decorated pluginConfig to the constructor of the
JavaPluginConfig and passed that along to the super class. It seems to work

To shed some light. My goal was to create a customizable linkpicker. The
linkpickers in the CMS can be configured to have a certain base (configued
with base.uuid), which I wanted to dynamically insert based on the tree I'm

Ah ok. I'm not really sure if this would fit my current problem, because the
