In the GUI Builder after editing pre-declaration code to add a custom annotation the needed class is found but not imported in the import section of the java file.

This mismatch with the usage on non graphical autocompletion.

Step to reproduce
 1 new java project
 2 add JFRame
 3 add a button
 4 create a package 
 5 add an annotation Dummy
 6 edit properties of the button code pre-declaration and use autocompletion to find Dummy, 

Code is well created the line :
@Dummy
    private javax.swing.JButton jButton1;

But Dummy is not imported

On a non graphical usage using autocompletion and finding Dummy annotation will create the import line

Workaround: "fixing import" is a workaround but make Netbeans a bit incoherent.
