Overwritten Null-Values @ merge

[rené giretzlehner]

Hi, I'm using 0.9.7 version. My problem is that when I merge detached objects via the entity-manager - ALL NULL-values which I set in the web-tier are being replaced by the values of the object-fields which are in the database. Is this behavior intended? Because it is necessary for me the reset some fields from the db-value to NULL again. Is it possible that I have made a mistake in the jpa-configuration - is there a section in the configuration where I can tell jpa to persist the NULL-values and NOT to overwrite them with the values from db? Thanks for your suggestions! All the best,   rené
