More than one Handler for a command [message #632622]

Hey,

is it possible to register more than one handler for an existing command?

What I am trying to do is to add a double click command for a table viewer that behaves differently depending on the active perspective.

So, what I did was to create a command with no default handler, and two handlers with the enableWhen properties set.

When I run it with only one handler it works the way I expect it, but when I add the second handler with a different perspective restriction the call to command.isEnabled() returns false.

Yes, it is totally possible, and commands are made for that!

You should try the activeWhen attribute.
