[TYPO3-mvc] Fatal error: Cannot access private property in AbstractDomainObject.php on line 260

Hi there,

is there no way to have variables in a model class for internal use only?

I have a variable:

    private $_last = NULL;


    public function getLast() {
        if ($this->_last == NULL) {

            /* some time consuming stuff */
        }
       
        return $this->_last;
    }

I do this because getLast gets called several times in one and the same
template.

Then I get the error:
Fatal error: Cannot access private property
XX\Domain\Model\BetriebRehaleistung::$_last in
/var/www/typo3_src-6.2.5/typo3/sysext/extbase/Classes/DomainObject/AbstractDomainObject.php
on line 260

Ok I can change private to protected. But why needs AbstractDomainObject
to access this property?

Even more strange is the fact that the same code works for other model
classes...

Cheers,
Till
