I guess I use event handler methods to set up page class fields a lot
less than the average . . . I basically only use the prepare event
from the Form component.
For your problem, I would have a getPrimaryKeyEncoder() with lazy
initialization:
@Retain
private PrimaryKeyEncoder primaryKeyEncoder;
public PrimaryKeyEncoder getPrimaryKeyEncoder() {
if (primaryKeyEncoder == null) {
primaryKeyEncoder = .... // create or get our primary key encoder here
}
return primaryKeyEncoder;
}
Sometimes I feel Tapestry 5 is so easy that people often start trying
a complex solution before the easy one. :)
