enterprise architect scripting - modify position of DiagramObjects

Question

I try to generate an activity diagram with help of my external java program. My problem: After I add an element (for example an Action) to the diagram I want to modify the position of it (left,right) because some elements are bigger than others.

My code:

Collection<DiagramObject> dobs = diagram.GetDiagramObjects();

//location calculation left out here
DiagramObject dob = dobs.AddNew(location.toString(),"");
dobs.Refresh();
dob.SetElementID(e.GetElementID());
dob.Update();

//center the position of the diagramobject on the left&right value
int horizontalDiff = dob.GetRight() - dob.GetLeft();
dob.SetRight(dob.GetRight()-horizontalDiff/2);
dob.SetLeft(dob.GetLeft()-horizontalDiff/2);
dob.Update();

If I check the values Left and Right of the dob-Object the values are changed. But when I open my EA Project they appears at the old position (before the centering code was executed).

When I execute the code to center all diagram objects after I opened and close the EA-Project it work's:

for(DiagramObject dob : diagram.GetDiagramObjects){
    int horizontalDiff = dob.GetRight() - dob.GetLeft();
    dob.SetRight(dob.GetRight()-horizontalDiff/2);
    dob.SetLeft(dob.GetLeft()-horizontalDiff/2);
    dob.Update();
}

But when I execute this without open EA-Project before, it changes the appearance not. Anyone have an idea why it work's after open the EA-Project manually? Here my goal in form of an image: my goal

Try to modify the t_diagramobject table.

Instead of using the SetLeft and SetRight methods, the elements in t_diagramobject have the Top and Left properties.

Put attention that the Top values are negative.

You Have to get the relevant element's ID from the diagram elements, then serch for this ID in the t_diagramobject and modify it.

Do not hesitate if you have any questions.
