composing commands vs executing commands inside doExecuteWithResult [message #66569]

I find myself creating AbstractTransactionalCommands that execute other
semantic commands in doExecuteWithResult.

Is this the right approach? Should I be composing commands instead?

thank you

Hello Vlad,

It is preferable if you use a composite rather than delegating to the
other command. By using a composite command the affected files and
undo/redo behaviour of its children will automatically be considered
when the composite is executed. If you delegate to the second command,
you need to ensure that your wrapper command correctly reflects the
affected files and undo/redo behaviour of its delegate.

Regards,
Linda
