Save order of EO objects to support database foreign key constraints.

Hey List,

I am importing a bunch of relational data into a project and when I try to save changes I get an error something like this:

Error when attempting to save data: EvaluateExpression failed: : Next exception:SQL State:23000 -- error code: 1452 -- msg: Cannot add or update a child row: a foreign key constraint fails (`valueA`.`valueB`, CONSTRAINT `TableA_tableBID_id_FK` FOREIGN KEY (`tableBID`) REFERENCES `tableB` (`id`))

I know it is because they are not written to the database in the order created. I have dealt with this in the past by doing incremental saving and other awkward things, but in this case that would be a total pain.

Any suggestions for the best way to deal with this?

Thank you,

Steve Peery
