How to add new DragDropEditPolicy [message #506216]

We are trying to add some customized drag-and-drop logic, when dropping certain EObjects onto the Diagram Editor in IDA (InfoSphere Data Architect) 7.5.2 - based on Eclipse 3.4.2.

We defined a new edit-policy class and registered it with highest priority by using the edit-policy provider
(extension point:org.eclipse.gmf.runtime.diagram.ui.editpolicyProviders).

It seems that the new edit-policy is installed, but then gets overwritten by the IDA native edit-policy
(com.ibm.datatools.diagram.logical.internal.ie.editpolicies. IEDnDEditPolicy), and our customized logic is never executed.

1. Is it possible to register two edit-policies with the same priority?
2. How can we make sure that our edit-policy will work without interfering with existing/future edit-policies?

Thank you very much for your help.
Regards,
Gidi

Hi Gidi,
afaik there isn't any priority management for edit policies.
EditPolicies have keys. If you want to override the existing D'n'D
behavior you should remove the existing D'n'D EditPolicy first
(removeEditPolicy(String key))

But you could also add your own editpolicy in addition to the existing
ones. Just call installEditPolicy(yourOwnKey,new
YourCustomizeDnDEditPolicy()) in createDefaultEditPolicies() of EditPart

I Hope it will help...
