Write to Data Store Entity failing with - object is an unsaved transient instance - save the transient instance before merging

saksheer

I am getting an error like - Details: org.hibernate.TransientObjectException: object is an unsaved transient instance - save the transient instance before merging: IAFCharacterDetailsAllegiancesDT6280 - while writing to a data store entity.

I have checked the child CDT, no values are being passed as null. Still no clue why am I getting this error. Can anyone help?

    Hi saksheer,

    go to parent CDT, click on key in row where is your reference to child CDT and check if you have set correct field relationship. I think you need Cascade=ALL behaviour.

    : I checked the "Updates to a parent value should also update associated child value(s)" in the Foreign Key setup. This helped me get rid of this error.

    However, it says that "This field has a One-to-Many relationship and Master-Detail (Cascade=ALL) behavior" - which should ideally mean that any update on parent should be "cascaded" to the child CDT too. But when I try to truncate the table for parent CDT from MYSQL, it does not let me do it, because of the foreign key constraint. I checked the relationship in the table for child CDT, the foreign key constraint is "restrict". Why is it restrict when the relationship in the CDT clearly says Cascade=ALL?
