I need put a "Activate Bar" how show the figure 2.

FIGURE 2

Details: The Lifeline figure is a rectangule Geral, with 2 rectangule
inside, one for "head and name" other custimized for "Line".
rectangule Geral has: border Layout.
Rectangule "head and name" has Stack Layout and Border Layout Data
Beggining. Rectangule "Line" has Stack Layout and Border Layout Data
Center.

The Rectangule "Activate Bar" is normal rectangule with minimium and
maximun dimension size features seted.

In the Mapping, i try to put a child reference of "Activate Bar" inside
node mapping of Lifeline, then this error is showed when i try paint the
Activate Bar.
"Could not open the editor: org.eclipse.draw2d.geometry.Rectangle cannot
be cast to java.lang.Integer"

ps.: I dont have problem with LifeLine figure, but with activate Bar
figure.

Any help is appreciate.

Danilo

Hello Danilo,

>java.lang.ClassCastException: org.eclipse.draw2d.geometry.Rectangle cannot
be cast to java.lang.Integer
> at org.eclipse.draw2d.BorderLayout.setConstraint(BorderLayout.j ava:273)
The problem is – you are trying to add child element into the figure with
BorderLayout (“Geral” rectangle).

By default Rectangle instance is used as a constraint in
>at org.eclipse.gmf.runtime.diagram.ui.editparts.ShapeEditPart.r efreshBounds(ShapeEditPart.java:177)

So, you have to either modify refreshBounds() of the EditPart representing
parent element (object on sequence diagram) or specify no layout managers
for the figure used as a container of child elements (I think you can compose
“lifeline” from several transparent rectangles securing the line drawn in
the center of figure and providing one more empty rectangle filling whole
space without any layout manager inside to be used as a child container).
