You can't uncheck mandatory checkbox for a PK.
As to the original problem, I am pretty sure I am not seeing this
behavior in Cayenne 3.0. Could be a bug in 2.0.4. Would it be possible
to try it out with 3.0?

I'm going to take a guess that the isMandatory="true" is firing first
before the PK is generated and assigned. Try turning that off and see
if it works. Cayenne should know that PKs are mandatory, anyway.

Hello,
I am using Cayenne 2.0.4 with Derby embedded.
I am getting a ValidationException "id is required" when I commit
changes
after creating a new object.
I have set the PK Generation Strategy to Database-Generated and set
the ID
field as Auto Incremented in the modeler.
In my map file the id field looks like this:
...db-attribute name="ID" type="INTEGER" isPrimaryKey="true"
isGenerated="true" isMandatory="true" length="10"....
I have also tested whether Cayenne thinks the adapter supports
generated
keys with the following code:
DataMap map = dataContext.getEntityResolver().getDataMap("MyMap");
DataNode node =
dataContext.getParentDataDomain().lookupDataNode(map);
DbAdapter ad = node.getAdapter();
System.out.println(ad.supportsGeneratedKeys());
and this returns true.
If I uncheck "Object Validation" for the data domain in the modeler
everything works fine.
However I would rather not turn off object validation.
Anyone have any suggestions on what I might be missing?
Thanks,
Mark
