Hi,

When I double click on a click to invoke Direct Edit, when the
createDeleteComand() of my DirectEditPolicy is called?
why it is trying to create a Delete Command?

Thank you

Whenever selection changes, the delete action checks to see if it's enabled. To do this, it get's a
delete command from the target edit parts and checks to see if that command can execute. This
should only happen selection changes, though. Is a new delete command being created even when
selection isn't changing?
