Well, I had this particular problem and had to use a workaround as it is not yet possible to do exactly that. The best way I came up with is what I suggested earlier : You use a button that points to a StateTransition in which you do your validation, then raise_user_error the message you want. When doing that, the client will stay on the latest displayed view, so it should be what need. There is no way yet to display a message with the possibility to resume execution, as the code you might want to resume is on the server when the message displaying is on the client. raise_user_warning sort of emulates that : when used, if the user clicks on 'Continue', it will re-execute the previously executed code then skip the warning. So even though it looks like execution did not stop, it did. You could talk to the tryton heads for more info, and do not hesitate to ask if my solution is not clear enough.
