Using 3.0 and setting Java Type for RosterSlot the in the Modeller to a
boolean, then generating the classes, then getting rid of the extra
methods - fixed the problem.
One slightly strange thing I noticed. In the client version the
generated class is:
public boolean getMonthlyRestart()
,
but on the server version it is:
public boolean isMonthlyRestart()
Shouldn't the signatures be the same?
thanks - Chris
