Hi!

  I'm using EOGenerator to generate my classes from the model.

Today, I found out that EOGenerator generates accessors using the trusted key/value operations, like:

    public String address() {
        return (String)storedValueForKey("address");
    }

    public void setAddress(String aValue) {
        takeStoredValueForKey(aValue, "address");
    }

This causes that, when I use setAddress(address), the value does not go trough the validateAddress method.

It is not supposed to. validateAddress is intended to be called _before_ setAddress is called. Right, wrong, or weird, that is how EOF is intended to work. Objects are permitted to be invalid and validity is checked during saveChanges().


When using form values and WOComponents, the values are actually set using validateTakeValueForKey which calls validate... before calling set....


This looks strange, but I suppose there are any reasons why EOGenerator authors prefered the trusted operators instead of the normal "takeValueForKey" ones. Anyone knows why? Is there a problem if I change the templates to use the normal operators?

Any changes that you make to that method are very likely to cause problems with EOF or stack overflow errors (if you are lucky).
