Product Version = NetBeans IDE Dev (Build 201209190001)
Operating System = Windows 7 version 6.1 running on x86
Java; VM; Vendor = 1.7.0_07
Runtime = Java HotSpot(TM) Client VM 23.3-b01

This was ignored in the redirected issue 218640 but it is not related to the duplicated issue:

I have a module with the following modules:
simple.marauroa.application.core.db
simple.marauroa.application.core.db.controller
simple.marauroa.application.core.db.controller.exceptions
simple.marauroa.application.core.db.manager

If I select all of them as public (Properties>Public Packages) the IDE adds
this to the pom:

                     <publicPackages>
                       
<publicPackage>simple.marauroa.application.core.db.*</publicPackage>
                    </publicPackages>

Only the package simple.marauroa.application.core.db is displayed as public in
the project explorer.

Only when I defined them as:

                   <publicPackages>
                       
<publicPackage>simple.marauroa.application.core.db</publicPackage>
                       
<publicPackage>simple.marauroa.application.core.db.controller</publicPackage>
                       
<publicPackage>simple.marauroa.application.core.db.controller.exceptions</publicPackage>
                       
<publicPackage>simple.marauroa.application.core.db.manager</publicPackage>
                    </publicPackages>

Had to reopen the module anyway due to bug issue 185897 to see the changes.
