I ask this question once per year, as every year it gives me great grief

I have two views, same table, each will have different limits and default ordering.. here is what I have so far

public function populateState($ordering = null, $direction = null)
    {
        // Initialise variables.
        $app = JFactory::getApplication();
        $session = JFactory::getSession();
        $acl = MyComponentHelper::getActions();

        parent::populateState('a.film_title', 'asc');
        $this->setState('list.limit', 15); 

        if($this->context == "films.latestfilms")
        {
            parent::populateState('a.creation_date', 'desc');
            $this->setState('list.limit', 10);  
        }
    }

The overall state works (film title, 15)

but the contextual one (lates films) doesnt

How can I correctly code this populate state to work

Thanks

Missing the component alias : com_xxxxx

There are 2 ways to get the model context :

1.
$this->context; (from the model itself) OR $model->get('context');
It contains the full namespaced context : com_xxxxxx.films.latestfilms

2.
$model->getState('context')
It only contains the relative context : films.latestfilms

- If you call getState() from the populateSate() function, you will end with a endless recursive loop. So you need to use the first method.

if ($this->context == 'com_xxxxxx.films.latestfilms')
{
	$this->setState('list.limit', 10);
}

Coding is now a piece of cake
