Mike,
If you want to initialize a field to be a certain value, you should
use the awakeAfterInsertion(EOEditingContext ec) method. Implement
it like this:
- (void) awakeFromInsertion(EOEditingContext ec) {
this.setBriefDatum(new NSTimestamp());
}
Modifying a set method to not have the correct signature is a huge
problem for KeyValueCoding (and probably many other things!)

Hi,
I´m in trouble with NSTimestamp. I´m using this to store the durrent
date to a database. While there is no need to edit this date I´ve
altered the acceorclass for the database object like that:
public void setBriefDatum()
NSTimeStamp value = new NSTimeStamp();
takeStoredValueForKey(value, "briefDatum");
}
When you hit the new button in my form a new object "briefe" is
initialisied ,which includes the datafield "briefDatum", I then
call the
"setBriefDatum" method and the date shows up in the connected
Formfield.
You can enter your data and hit the save button. After that an
exception
occured. Funny thing, it occures when all my code is finished and the
page is displayed again. Data is saved to database, all aftersave work
of my code is executed, don´t know where error might be.
The error message:
