Hi,

Yes, that’s a good idea. We’ve also been kicking around putting the “on change” scripts directly on the tags, which would let you define this directly on the data type. We might consider it for 7.7.

yes please. I am assuming that this would be gateway scoped? either that or give us access to the list of tags in the on change section of each script via scripting. thats a hot ticket item for me.
