Shouldn't the signatures be the same?
Yeah... Looking at the client templates, there's no explicit handling
of boolean attributes. This probably also means that primitives
haven't been fully tested with ROP. Let me open a Jira on that.
Thanks,

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?

Can't say for sure what this is, but can you try it with 3.0?
BTW, 3.0 supports direct mapping of primitive booleans (boolean for
the ObjAttribute; BOOLEAN for the DbAttribute; TINYINT in MySQL)

I have a problem that occurs when a fetch is done from the ROP
client, which causes the server to load client DOs using the

I have checked that all the latest code and mapping information is
on the Tomcat server. The problem occurs when re-fetching a
RosterSlot that the client application created. What is
interesting is that if I reboot Tomcat then everything works as
expected - showing that the new RosterSlot did in fact make it
successfully into the database. So it is a ROP database refresh
problem.
Is there anything else I need to check, or some easy way of
debugging this? _RosterSlot.monthlyRestart is a Byte variable in
both client and server versions of the DO. I do have methods on
the subclasses that serve to convert between Byte/Integer/boolean:
public boolean isMonthlyRestart()
{
boolean result = true;
if(getMonthlyRestart().intValue() == 0)
{
result = false;
}
return result;
}
public void setMonthlyRestart( boolean b)
{
if(b)
{
setMonthlyRestart( Utils.ONE.byteValue());
}
else
{
setMonthlyRestart( Utils.ZERO.byteValue());
}
}
From the Modeller I can see that MONTHLYRESTART is a TINYINT in
the MySql database and in the DO the Java Type is a Byte.
