DnDSupport.js reports object not found

Question

While trying to create a portal / zone / UI Map in CC&B, I could not get my new Zone/Portal window to show from the CC&B menu. When I selected my new Zone/Portal from the menu, Internet Explorer showed my filters. When I clicked the Refresh button below my filters, IE showed a blank area below my filters and then a yellow exclamation point on the status line and when I double clicked the exclamation point, the popup message stated that DnDSupport.js could not find the object. The error was on line 840 (of course this will vary amongst different distributions of the framework).
The problem was that there was a mis-spelling of a field name on one of the Zone's Filters. The name used in the Schema on the UI Map for "OraField", must be spelled the same as the name in the "xpath=" statement used inside the Zone's User Filter fields. I had an "xpath=" field name spelling that was wrong. I found the resulting error message to be cryptic and hard to figure out, so I wanted to post this message in case another developer ran into the same issue. If you get this error, double check spelling between your UI Map and Zone Filters.

I meant this to be a topic for review for others...and not exactly a question that needs to be answered.
