| Draw edges after dragging an entity on the diagram [message #1597395] |

Hi,
I would like to mimic the behavior of the ecore diagram editor in the sense that it is largely unsynchronized and you have to drag classes into the diagram to get them displayed. A nice feature is that in case an association exists between two classes, it is automatically drawn.
My metamodel contains elements representing an association between to entities; e.g. I use element based edges.
So far I managed to create a tool that allows me to drag an entity from a tree into a diagram.
What would be the most elegant way to draw any related edges? Do I have to iterate manually over all association elements and create edge views one by one? How does the ecore editor manage this?
Greetings,
Wilbert.

The most elegant way to draw any related edge between existing
nodes/containers (or list elements, border nodes, ..) on an
unsynchronized diagram would be to force the synchronization of the
corresponding edge (resp. node, container) mappings: select your mapping
(Edge, Node, Container) in the VSM editor, then select the Advanced tab
and select "Synchronized". You will find detailed information in the
Synchronization section of [1].
