Probably Scene.validate() was not called after last change.
Can anybody attach project with "saved sequence diagram"?
let's evaluate in mobility first
Sorry, I mangled the project with the problematic diagram and I am now unable to reproduce the behavior. I am attaching a new project (created with Build 200811100001) with the same sequence diagram except for the my_controller timeline as noted below. Several things I've noticed: - The problem diagram was copied and renamed, so that it was cross-linked with the original diagram (which only contained timelines, no messages) - The problem diagram had multiple messages originating from a single timeline. With one exception I am no longer able to create more than one transaction on an active segment. The exception appears in the attached project - the render message from my_controller to listing:View was created following the void return from init_queue_element. When the diagram was reloaded after closing the project and restarting Netbeans, that message is placed between the init_queue_element message and its return. The attachment contains saved snapshots of the project at key points during diagram creation. The version tagged _gettingFlaky is beginning to exhibit some of the odd behavior of the original. Hope this helps. - Carl

Looks like Visual Lib issue, reassigning.

Last reports from 6.7, mentioning UML. Not a general problem of platform/graph but a problem of the use in UML.
