Probably Scene.validate() was not called after last change.
Comment 3 Sergey Petrov 2009-04-14 16:02:54 UTC
Can anybody attach project with "saved sequence diagram"?
Comment 4 Sergey Petrov 2009-04-15 11:07:55 UTC
let's evaluate in mobility first
Comment 5 chcornwell 2009-04-21 20:24:30 UTC
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.

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.
