I have an AbstractHandler that should execute an EMF command, and the handler should be enabled when the command is enabled. The command itself is dependent on the workbench selection. If I override setEnabled() in the handler, and create the command to test it for executability, can I cache the created command so that I can reuse it during execute?

In my specific use case I have an EMF command, but the question is more towards if Handlers can share some state between setEnabled() and execute(), so I think platform is the right place to ask.
