Troubleshooting: Why do my features redraw after I place a feature using the Attribute Editor?
Consider the case in which someone adds an open switch and de-energizes many features downstream. You may want to see the updated features rendered correctly. Unfortunately, Feeder Manager does not track each updated feature in order to invalidate it and manage the envelope of the features affected. Feeder Manager invalidates the screen.
A bug was fixed in 8.2 SP1 to prevent redraw when placing features that were not affected by Feeder Manager. However, for features that can be affected by Feeder Manager, this works as designed.
