The 21.1 update put the variables in the Edit Selected Objects(ESO) into groups like Fixed Resource, Queue, etc. Not all object types were included in this and that means they have...0 variables in the drop down to copy. Is the update incomplete? Is the ESO tab being retired?
Additionally, copying triggers has been removed from this menu as well as a number of other features for objects that can use this menu at all.
The code I wrote (and want to copy). It reads the text's name and references a table value accordingly.
The old (21.0) ESO tab.
The current (21.1) ESO tab.
