Current variable declaration code inside Code Customizer, does not allow for editing, so new Java 7 Swing features, involving the use of generics for JList and JComboBox, cannot be properly set-up.

The following can be declared in the initialization code, as custom creation:
jComboBoxSelections = new javax.swing.JComboBox<>();

but inside the variable declaration code, we have:
private javax.swing.JComboBox jComboBoxSelections;
which is non editable.

This leads to some sort of inconsistent code, where the component gets initialized by its own generics definition, while its own variable does not.

I suggest to make possible the editing of such a variables section, same as the custom creation.
