Hi ,I am using cayenne 2. I want to update an employee object. This object is related to employee table in the db. I generated this data object(along with it's super class) and table query using modeler. I am able to write insert, delete and select methods for this object easily. can you tell me whether the below is the correct way to update/modify the object? I thought that the object that is sent for updation / modification usually exists with data context, as the object is to be retrieved from the database. During this getting/selecting process using data context, it will be registered with data context. So, i can use localobject without any doubt. all the cayenne examples lack modification code. Object dataObj = this.getDataContext().localObject(employeeDOProto.getObjectId(),employeeDOProto); EmployeeDO anEmployeeDO = null; if(dataObj != null) { anEmployeeDO = (EmployeeDO)dataObj; anEmployeeDO.setPersistenceState(PersistenceState.MODIFIED); } this.commitChanges();
It isn't clear what you are trying to do with the code above. What is employeeDOProto? Why are you moving it to another context and then assigning it to a different variable?
