Description mclaborn 2016-06-24 20:53:38 UTC
Product Version = NetBeans IDE 8.1 (Build 201510222201)
Operating System = Linux version 4.4.0-24-generic running on amd64
Java; VM; Vendor = 1.8.0_92
Runtime = Java HotSpot(TM) 64-Bit Server VM 25.92-b14

I have a class name MMList that is a subclass of javax.swing.JList.  The JList class does accept a parameter <E>, but MMList does not. 
When I drop a MMList instance on a GUI form, the declaration code include a parameter type of <String>. 
  private<String> listDebugPoints;

Since the MMList class does not accept a parameter, the variable declaration should not include a parameter.

The instantiation code is also incorrect, using an empty parameter <>.

Tomáši, can you please evaluate this issue when you have free cycles? Thanks!
Comment 3 Tomas Pavek 2016-09-15 14:37:40 UTC
The workaround is to select the MMList component, go to Properties > Code and clear Type Parameters property. The property should not be automatically set in this case, it's a bug that it is.

Thanks for that workaround.  It will certainly save me some time.  I've been closing the file in NB and editing outside NB.
