Hello community,

I want to implement my own DeleteFromDiagramCommandHandler which should inherit from org.eclipse.papyrus.uml.diagram.common.handlers.DeleteFromDiagramCommandHandler. How can I accomplish that Papyrus use my DeleteFromDiagramCommandHandler instead of the default Papyrus handler in all Use Cases?

In the plugin.xml I added a handler and a provider with my own Delete Handler and own ActionStateProvider, but this was not enough to override the all deletion cases, e.g. the deletion with "Del"-Key.

Thanks in advance.

Hi Erik,

The extension point org.eclipse.ui.handlers should be sufficient. Specify a handler for the command org.eclipse.ui.edit.delete, and provide a specific "activeWhen" condition (It should be more specific than the one defined in Papyrus, to have a higher priority and actually override it)
