Description mclaborn 2015-10-23 21:59:14 UTC 
Product Version = NetBeans IDE 8.1 RC2 (Build 201510122201)
Operating System = Linux version 3.13.0-66-generic running on amd64
Java; VM; Vendor = 1.8.0_51
Runtime = Java HotSpot(TM) 64-Bit Server VM 25.51-b03

Reproducibility: Happens every time

Holding the shift key while dropping a component on a GUI form from the Palette is supposed to allow you to add more than one in succession.  This is not working in 8.1 RC2.

1. Create a new JPanel form
2. Open the Palette view
3. Click the Button component
4. Drag to the GUI form
5. Hold Shift key and click to place the button
6. While continuing to hold shift, move the mouse to the right.

Expected:
It should have the outline of a Button that can be dropped on the form again.

Actual:
Does not

This was caused by a really amateurish change made at the last moments of 8.1 release (best time to do stupid things): http://hg.netbeans.org/jet-main/rev/e73a7a30219c.

Hopefully fixed now:

This is a really embarrassing bug, nominating for the 8.1 patch.
