ROP - server DOs to client DOs failure
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 values from server DOs:
<
Can not set java.lang.Byte field
org.strandz.data.wombatrescue.objects.cayenne.client.auto._RosterSlot.monthlyRestart
to java.lang.Integer
>
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.
thanks - Chris

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.

Re: ROP - server DOs to client DOs failure
Posted by Chris Murphy <ch...@strandz.org>.
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

Re: ROP - server DOs to client DOs failure
Posted by Andrus Adamchik <an...@objectstyle.org>.
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)
