Customize Modeller by adding forms to stencil

[paoloa_]

Hi everyone!
I'm currently trying to customize the BPMN modeller present in Activiti Explorer by adding a bunch of CMMN elements.
Is there a suggested procedure for this kind of implementation?
I gather I should start by adding new elements to the stencilset.json file, but I'm confused on the following steps… any help would be welcome.

I created a custom class in the org.activiti.bpmn.model package for each new element… but i'm still at a loss on how to connect this class with the stencil… there's bound to be something I'm missing…

Hi,
If you didn't manage to solve this problem, I may help.
I'm also wondering how it works on Activiti6 because there is no stencilset.json anymore :s
