Hello,
In my diagram when I right click on connection line (polyline connection
in graphical model) and select Format / Line Width all possible selections
are disabled. Same thing happens when I select Line Type or Arrow Type.
However Line Style as well as Line Color options are enabled.
I checked LineWidthAction.calculateEnabled() and found that
style.getLineWidth() there is -1. I also checked
LineTypeAction.calculateEnabled() and found that style there is null. But
I have line width in my graphical model set to 1.
Thank you for helping me
Igor

Hi Anthony,
Thank you very much for your answer. I found the classes you refer to. My
XXXXConnectionViewFactory.createStyles contains the code you mention. It
looks like this:
List styles = new ArrayList();
styles.add(NotationFactory.eINSTANCE.createConnectorStyle()) ;
styles.add(NotationFactory.eINSTANCE.createFontStyle());
But this code is never called. I set up a breakpoint there and it is never
reached. Actually, it seems to be a reason why these styles are not
defined. How can I make this code run?
Thank you agian,
Igor
