Help Content disabled after 1 use. (Issue #153793) Resolved ?

I see the issue 153793 is set to RESOLVED  see
http://www.netbeans.org/issues/show_bug.cgi?id=153793

In my RCP app (Nb 6.5 based) when the user selects the Help->Help
Contents it pops up as expected. So far so good ....

Now, when closing the Java Help the Help->Help Content menu is
DISABLED. Only way to get it back is to exit the app and restart.

I need some help to understand what I should do to make this enabled
all the time. In particular in view of this bug is set to resolved.
