> 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);
> org.objectstyle.cayenne.CayenneRuntimeException: [v.@CAYENNE_VERSION@ @CAYENNE_BUILD_DATE@] No DbEntity for ObjEntity: MtTable1
> 	at org.objectstyle.cayenne.DataObjectUtils.buildId(DataObjectUtils.java:352)
> 	at org.objectstyle.cayenne.DataObjectUtils.objectForPK(DataObjectUtils.java:167)
