I am using a WOToOneRelationship and having some issues with the editing context becoming "dirty" when no changes are made to the object itself.I have a User entity with a "to one" relationship (department) to my Department entity. Here are the bindings for the WOToOneRelationship component in WOBuilder used modifying an instance of the User entity, called validatedUser.WOToOneRelationship1: WOToOneRelationship { relationshipKey = "department"; sourceObject = mySession.validatedUser; sourceEntityName = "User"; uiStyle = "popup"; dataSource = allDepartments; destinationDisplayKey = "shortDescriptor"; }(FYI. I followed some tips on Kieran's website (http:// homepage.mac.com/kelleherk/iblog/C183784902/E951811406/index.html) to display all of the departments contained in my Department Entity. This is because I have ERExtensions as part of my application's frameworks.... Thanks Kieran!).All is working fine and I can display the validatedUser (an instance of the User Entity) and his/her department. If I change the department from the WOToOneRelationship popup, and save the changes to the editing context, the changes are saved successfully to the database.My problem is that when I merely display the validatedUser and do not make any changes, I am still seeing the object as being updated by logging the updatedObjects() of the editing context. If I remove the WOToOneRelationship from the page, and replace with a simple WOTextField, I do not see the object as being updated , when I do not perform any changes to the user. This is the behavior I would like to see, and would expect, when using WOToOneRelationship.
Try updating your User like...
public void setDepartment( Department aDepartment ) {
Department currentDepartment;
currentDepartment = department();
if ( currentDepartment != aDepartment ) {
...
}
}
That way your entity will not "update" itself when you're simply
giving it the same value.
