Thanks for the quick reply.  I didn't see that in the best practices.. guess I should go back and read it again

I'll move it all to the proxy then.

I was wondering if there is a way to send a notification or something to a command that's currently running.  Here's the setup of what I'm trying to do.

I have a project proxy which does all of the manipulation of the project elements in a work directory.  The user can then save off an archive which is a long running process.  To implement the archive, I created an archive command that is run and has to use things like setTimeout to keep the UI responsive (which really just updates a progress bar) while it's running.

I now need the ability to allow the user to "Cancel" the archive functionality.  However, I can't figure out a way to let the the command know that it needs to be canceled without using any hacks like setting something in the proxy or something.

I considered making a "helper" proxy to just handle saving and loading to/from an archive (they need to be able to cancel loading also) and setting a "cancel" attribute on that guy but I thought I would ask if anyone had any better ideas or if this should've been a helper proxy all along or any other suggestions/comments.

Thanks,
Tracy
