ConnectionDecorator text decoration [message #758536]

I attach a Text to a Connection using a ConnectionDecorator (the same way this is done in the tutorials) but it seems that the text box is always transparent.
I tried to set a background color, I tried setFilled(true), I tried setting it using a Style, I even tried setTransparency() but nothing works.

I thought of using a simple rectangle Shape but I didn't find out how to add a ShapeContainer to a ConnectionDecorator.

What I try to achieve is to have this kind of hierarchy:
ConnectionDecorator
> Rectangle ShapeContainer
>> Text

Alternatively, does someone know how to make the Text box opaque?

Thanks for your help,
-Patrick

Patrick,

this should be possible by setting a rectangle as graphics algorithm to the
connection decorator and adding a text as child. Somthing like that:
ConnectionDecorator textDecorator =
peCreateService.createConnectionDecorator(connection, true, 0.5, true);
Rectangle rectangle = gaService.createRectangle(textDecorator);
Text text = gaService.createPlainText(rectangle);

Don't forget to set colors, sizes and location accordingly.

HTH,
Michael
