Can someone give me an example of how to set SelectBeforeUpdate and
DynamicUpdate on a mapping of 2 or joined tables? I have a concurrency
issue, where old data is overwriting recently changed data by another
session.
For example tablea is joined to tableb in the mapping. I open a form for a
record and change a value in tablea. Another user changes a value in
tableb while I still have the form open. I save and the value in tableb
reverts to the value I had.
Here is my code. I tried adding the statements highlighted below, but it
did not resolve the issue.
public class JobMap : BaseJobMap<Job>
{
public JobMap()
{
Table("fcfgthd");
/* LAL - 04/16/2013 - Added SelectBeforeUpdate and
DynamicUpdate statements to prevent overwriting newly updated data*/
SelectBeforeUpdate();
DynamicUpdate();
Id(o => o.Pkey, "fh_pkey");
Join("fcairhd", a =>
{
a.Optional();
a.Fetch.Join();
a.KeyColumn("hd_pkey");
MapAirJobProperties(a);
});
Join("fclegs", m =>
{
m.Fetch.Join();
m.KeyColumn("fl_pkey");
MapJobLegProperties(m);
});
}
}
}
Thanks!
