Hi Chip,
I'm borderline-ignorant on how to make bundle commands, short of cobbling other things together and hoping they work. I tried just making a command in the bundle editor that said "rescan_project", but that erases the entire contents of the page that I am working on. I obviously am missing something fundamental. Any thoughts?
Check that the "Output" setting on the command (it's a dropdown below the main text box in the bundle editor) isn't set to "Replace Document" -- I think you want to just "Discard" the output.
Also, I think "Input"(s) wouldn't hurt to be set to "None" or "Nothing"
Does that help? -steve
