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!

This is what you call a component builder. I was able to master using this in a very short time and the resulting component works like a charm. Not just a basic component builder but a fully working component builder with forms fields tables all ready to go. You can make the list and item views to display in the front and back end. Also there is a great forum just starting to evolve and I'm sure this will grow very rapidly when you all realise how good this tool is.
