[fw-db] Re: Unexpected behavior from Zend_Db_Table_Row_Abstract::setFromArray()

Here's something interesting.  As long as I pass an array of data into
the row upon instantiation, setFromArray() works as I expected it to.
See the test below:

    /**
     * Tests Zend_Db_Table_Row->setFromArray()
     */
    public function testSetFromArrayWorksWhenPassingArrayDuringInstantiation() {

        $row = new Zend_Db_Table_Row(array('data' => $this->_data));

        $this->assertEquals(3, count($row->toArray()));

        $this->assertEquals(1, $row->row_one);
        $this->assertEquals(2, $row->row_two);
        $this->assertEquals(3, $row->row_three);

        $updatedValues = array(
            'row_one'   => 7,
            'row_two'   => 8,
            'row_three' => 9
        );

        $row->setFromArray($updatedValues);

        $this->assertEquals(7, $row->row_one);
        $this->assertEquals(8, $row->row_two);
        $this->assertEquals(9, $row->row_three);
    }

Since I'm running unit tests on a custom row class, I think I'll use
the technique above for further testing in this case.

Do you guys see a problem with that going forward?
