Im trying to figure out how I can use the Tree Interface tool to update a Select Tool. I have used a List Box Interface tool that connects to a Action Tool and the Action Tool to a select. In this configuration the Action Tool has an action type called "Update Select with multi-select ListBox". This action type is not available in the Action tool when it is connected to a Select Tool. Ive also noticed that the Tree Interface Tool passes the "Key Field" into the connected Action Tool instead of the "Description Field". I would simple like to replace the List Box with a Tree. Is that possible? How would I configure things to accomplish this? Any help/examples would be greatly appreciated.
