Now it is solved,

the polygonal representation from the parametric object should be taken from current state to object.
(like Yannick suggested)
but the dirty state needs to be read from the cache.

Yannick, thanks!
Could you please explain why the cache hasn´t been updated ?
Best wishes

The initial question for this topic has been solved: messaging between the generator and its linked object, more precisely getting the dirty state from the linked object (the original title of the topic isn't event not meaningful).
Please create a new thread for new questions.

Feel free to rename this thread to suit the topic, Yannick, no problem.
That´s all not that meaningful...enjoy your finishing time

Hi Martin,

I'd really like to help you but we need to have an organized forum.

You can create a new topic with the current script for the Python generator, the issues with it and I'll be happy to help you .
