How to properly save children panels from the parent panel?

I have a parent QPanel which has 2 children QPanels.  Furthermore, the parent QPanel has a save button.  Thus, parent panel looks as follows:

class MyPanel extends QPanel 
{
    public $panel1;
    public $panel2;
    public $btnSave;

    public function __construct( $objParentObject, 
                                     $strPanelRightControlId = null, 
                                     $strControlId = null )
    {
        //call the parent's constructor first
        try {
            parent::__construct($objParentObject, $strControlId );
        } catch (QCallerException $objExc) {
            $objExc->IncrementOffset();
            throw $objExc;
        }
        
        $strDraftsPath = sprintf(__DRAFTS__, 'default');
        $this->strTemplate = $strDraftsPath . '/my_panel.tpl.php';
        
    $objFc = Zend_Controller_Front::getInstance();
    $intId = User::AutoloadId();
    
    $this->panel1 = new Panel1( $this, $intId, 'panel1');
    $this->panel2 = new Panel2( $this, $intId, 'panel2');
    $this->btnSave_Create();
}
    
public function btnSave_Create() 
{
  $this->btnSave = new QButton($this);
  $this->btnSave->Text = 'Save These Changes';
  $this->btnSave->AddAction( new QClickEvent(), 
                             new QServerControlAction( $this, 'btnSave_Click' ) );
  $this->btnSave->CausesValidation = $this;            
}

public function btnSave_Click()
{
  $this->panel1->btnSave_Click();
  $this->panel2->btnSave_Click();
}

Next, each child panel has its own validation and initialization methods but when I click the save button, the information in panel1 doesn't get properly saved.  If anyone has any ideas as to how to resolve this, please feel free to post.

Thanks in advance,

The issues that I was having with Panel2 has been resolved.  Now, Panel1 simply doesn't want to save the data to the database.

conrad,

out of curiosity, is there a difference between trying to call save() on an existing record (e.g. so it should be UPDATE-ing an existing row) vs. trying to call save() on a new record (e.g. so it should be INSERT-ing a new row)?
