Description mienamoo 2012-06-06 09:42:52 UTC 
Created attachment 120417 [details]
Screenshot showing the dragged icon still being displayed

NetBeans build 201206050001
JDK 7u3 32-bit

Steps to reproduce:

1. Create a new standalone NetBeans platform module, with one TopComponent and one JPanel form.
2. In the constructor of the JPanel form, throw an exception.
3. Compile the module.
4. Open the TopComponent in the GUI builder.
5. Drag the (now misbehaving) JPanel onto the TopComponent in design view.
6. The warning "The component cannot be instantiated. Please make sure it is a JavaBeans component." is display as expected. However, the component that was being dragged is still displayed (see attached screenshot with annotation) when OK is clicked to dismiss the warning.
7. Now click on the TopComponent in the design view, and the warning message is displayed a second time. Then the icon disappears.
