Show extrafield in generic.php on category overvie was created by Wouter

Hello,

We are developing a website based on k2. For this we make use of the extrafields to give an article an specific css class.

But when we use the archive extension this class is not applied and we get an error.

This is the error we get

Warning: Invalid argument supplied for foreach() in /home/recall/domains/domain.com/public_html/templates/mytemplate/html/com_k2/generic.php on line 19

Below you will see the code

<!-- START: Call to prepare extra fields -->
<?php  
//convertArray to use ids as key
$extrafields = array();
foreach($this->item->extra_fields as $item)
{    
$extrafields[$item->id] = $item->value;
}   
?>

I think you can get around all of that by using the new extra fields capabilities in 2.6.2

I'm almost certain that code, which was introduced in K2 v2.6 for displaying individual extra fields, doesn't work in generic.php.

Maybe I'm wrong, but I've done couple of test and I couldn't call individual extra fields from generic.php.

In template files you can call extra fields with $this->item->extra_fields.
In generic.php extra field object is accessed through $item->extra_fields.

So i tried

<?php echo $this->item->extraFields->extrafieldalias->name; ?>
<?php echo $this->item->extraFields->extrafieldalias->value; ?>

and

<?php echo $item->extraFields->extrafieldalias->name; ?>
<?php echo $item->extraFields->extrafieldalias->value; ?>

In both cases extra fields didn't show up.
