Re[2]: ROP: validation and callbacks

Understood.

About my first question.. I tried to invoke manually validation (forSave) from CayenneDataObject to my client PersistentObject (i.e. to copy-paste the code). Still this didn't work.
First, the ObjEntity.dbEntityName and ObjAttribute.dbAttributePath are nulls while working on client. This is not so bad since i can make some workaround by setting them to needed value.
But the problem is, that client's DataMap, which is accessed by ObjEntity.getDataMap() has no DbEntities loaded, i.e. dbEntityMap is empty, while objEntityMap is correctly fulfilled. So i cannot access constraints described for my DbEntities in DataMap.
Is there any way i can fetch DBEntity object from client?

Thanks,
Andrey

Agreed, totally makes sense. Could you please open a feature request  
in Jira:

I've found the answer: it turns out that client 'ObjAttribute' descendant, 'ClientObjAttribute' needed validation information. I think it is a good idea to make those 'isMandatory' and 'getMaxLength' methods members of 'ObjAttribute' so that the same validation code would work on client and server (server's objattrs will reference to DbAttribute). How do you think?)
