Description Alain Le Guennec CLA 2011-06-29 06:46:28 EDT
Moving a port can cause class cast exceptions.
To reproduce:
-Select a port of a block on a BDD.
-Make sure the mouse curson changes to the move symbol (and not a resize symbol).
-Try to move the port.
=>Exception raised in error log:
java.lang.ClassCastException: org.eclipse.papyrus.diagram.common.locator.PortPositionLocator cannot be cast to org.eclipse.draw2d.geometry.Rectangle
