It's working fine many thanks for the help.
What I didn't know was that it was possible to interact with the designer using the JavaScript object added to the "window".
I hope this interaction helps me fixe the consecutive saving issue I'm having...when I save a process and try to save it again without refershing I get :"Unable to save this asset, as it has been recently updated by [guest]". Do you think it's possible to issue a refresh to the iframe through the JavaScript?
Thanks again
