Hello Admin

Can you help? I am attempting the rather boring task of retrieving the last 5 records from a table.

From the notes view I use:

	$model = $this->getModel();
	$model->setState('list.limit', 5);

in an Ajax context. I tracked the problem down to the populateState in the model list class, forked and commented out the "'list.limit', 0" line.

	/**
	* Method to auto-populate the model state.
	*
	* @access	protected
	* @param	string	$ordering	
	* @param	string	$direction	
	*
	* @return	void
	*/
	protected function populateState($ordering = null, $direction = null)
	{
		$jinput = JFactory::getApplication()->input;
		$layout = $jinput->get('layout', null, 'CMD');
		$render = $jinput->get('render', '', 'CMD');

		if ($layout == 'ajax')
		{
			$this->setState('context', 'ajax' . ($render?'.'.$render:''));
			//$this->setState('list.limit', 0);
			//$this->setState('list.start', 0);
		}

Still my model returns the first 20 records.

I don't know what else is killing the limit statement of the model so I give-up for now.

Any help would be a help and appreciated!

For starters it's just so easy to design an app in a way that I'm used to i.e. database first then views followed by customization. The fork system is pure brilliance from a developer standpoint as I can override things and still add and update my projects with minimal effort! Truly amazing to be able to build components in Joomla using incremental refinement without having to do everything by hand. Thanks for the great tool! I am so much more productive now than ever and I can't imagine building components any other way!!!!
