Description

While DataObjectUtil.objectForPK takes ObjectContext as an argument, using it on the remote client is not possible. The following exceptions happen on various overloaded calls:

1. This will require method signature change:

DataObjectUtils.objectForPK( c1,new ObjectId("MtTable1", "TABLE1_ID", 1));

java.lang.ClassCastException
at org.objectstyle.cayenne.DataObjectUtils.objectForPK(DataObjectUtils.java:276)
at org.objectstyle.cayenne.remote.ClientChannelEventsTst.testSyncSimpleProperty(ClientChannelEventsTst.java:93)

2. This should issue a query instead of doing DbEntity lookup:

DataObjectUtils.objectForPK(
c2,
ClientMtTable1.class,
1);
