Bug 101549

This is a pretty serious bug.

Because of this bugs it becomes difficult to maintain sequence diagrams.
Try inserting a new message in the middle. You'd have to painstakingly select and move each message individually because otherwise your diagram gets totally messed up.

1.3.92 is "ancient" in terms of Umbrello development speed, please use at least
1.4.1 (or better yet, 1.5beta2)

Hola, not so quick closing that bug. 
Shouldn't you verify it first?

Anyway, I'm using 1.4.1. This problem is not resolved.

Hm, well I tried with the branches/KDE/3.5 of the KDE Subversion repository
and it works if you select the *object boxes* (not the messages).
However, as far as I recall the corresponding bug was already fixed in 1.4.1.

Thanks for checking Oliver.
This error report consists of three issues. Let me clarify my findings with each of them.

1. Moving messages after a rectangular select gives unpredicted result
As soon as you try to move them the selected messages jump to the top of the diagram, messing it up. This is the biggest problem for me.
See attached 'rectmove.png'

2. The rectangular selects messages outside the rectangular area.
This is slightly different behavior from the original bug report because it does now select messages (1.4.1). The reason I mention it is that it still doesn't select the intended messages. 

See attached 'rectselect.png'. 
The selection area is highlighted red. 'terminate' and '__auditAccounts' are outside the selection rectangle but still selected. 

3. Moving messages after shift-selecting.
Doesn't move all the selected messages, only the one you happen to have the cursor over.
In addition, you cannot move lower beyond the point the object bar reaches down, even if other objects have bars reaching down further.
See attached 'shiftmove.png'
- Moving 'createModel' down does not move 'hasModel', although both are selected.
- 'createModel' cannot be moved further down than shown here. (eg, the object bar runs out of rope :). It really should be able to move down further.

In addition, it doesn't allow you to move beyond the available length of the
object bar.

Thanks for providing more info.
I confirm your findings.
In fact, one of them I've already fixed a few minutes ago -

I found a bug in ToolBarState::setSelectedWidget() that
caused not all object boxes to be selectable. This is fixed
by the following patch:

setSelectedWidget(): Increment the messages iterator only once.
