Thanks Rik,

this does work.
I'm sorry that I keep asking, but I'm trying to understand this.

I wonder if this is the correct way to address the $m_oTextBoxes array.
That array should be treated as if it were private, I suppose..?

Actually, I should have an interface method to call this array:


class HTMLForm {
var $m_oTextBoxes = array();


// Added method: ========================================

function getTextBoxByID($sID) {
return This->m_oTextBoxes[$sID];
}

// ======================================================

function addTextBox($oTextBox) {
$this->m_oTextBoxes[$oTextBox->getID()] = $oTextBox;
}

}

Then, I still have the question how to call the right instance of the
TextBox-class's getOuterHTML method.

Because this will not work here: echo
$oForm->m_oTextBoxes["Nr"]->getOuterHTML();


Thanks for your patience!
Ramon.
