Alex,

I created new EC for each Entity instance but I got to messages :

relationship Exception :

java.lang.RuntimeException: You crossed editing context boundaries attempting to set the 'eoTypeTiers' relationship of <org.utt.rfcct.serveur.modele.rfcct.EODomaine pk:"null"> (in EC er.extensions.eof.ERXEC@1be3e4c5) to <org.utt.rfcct.serveur.modele.rfcct.EOTypeTiers pk:"2"> (in EC er.extensions.eof.ERXEC@4dbed348).

It's not is to use EC.saveChanges() :(

Thanks

Bonjour Alexis,

Well come back to cocktail :)

So when I want to set the relationship I got this in stacktrace :

avr. 03 14:16:48 RFcct[8485] INFO  er.transaction.adaptor.Exceptions  - Database Exception occured: java.lang.NullPointerException
java.lang.NullPointerException

    at er.extensions.ERXExtensions$KeyValueQualifierSQLGenerationSupport.sqlStringForSQLExpression(ERXExtensions.java:348)

Looks like some attribute in your eomodel doesn't have an External Type set. This is mandatory.
 
issue corrected, thanks a lot.
 
 

I deleted my build directory and clean everything. it seems the instruction domaine.editingContext().saveChanges(); save all EOEntreprises in the context and not domaine Entity only? Why? I want just to save domaine and not all entities like CAPACITE, MATIERE and so one.
An editingContext observes all changes from the eo's it "contains", see it as a sandbox. You can't select specific changes. You could use one EC for your "domaine" changes et one EC for the other changes.
 
So I must create new EC Entity instance ? I try it.

Bonjour Raymond,

What's the NPE stacktrace ?
the eomodel looks fine too me as it allows null relationship. It seems you have a refresh pb in your eclipse, try to refresh/clean your projects.

Cheers,

Alex

Hi List,

I have a big problem with my relationship one-to-many.
When I set domaine.setEoTypeTiersRelationship(ctrl.getSelectedTypeTiers()), I got java.lang.NullPointerException and When I dion't set the relationship I got "<er.extensions.validation.ERXValidationException object: <org.utt.rfcct.serveur.modele.rfcct.EODomaine pk:"null">; propertyKey: eoTypeTiers; type: MandatoryToOneRelationshipException; additionalExceptions: ()>".

What I am doing wrong? I try to do domaine.editingContext().saveChanges();

Here is How my relationship look like in model

Thanks for your advices
