Ok so I have a bunch of views, called by different controllers that
each reference the same element 'post'. Each controller passes a set
of parameters to the element via the renderElement('post', $data)
method. All the parameters are passed through $data and all is peachy.

However, ONE of the views has a special little parameter called
'ticker' passed through $data['ticker']. In my view I have set
$data['ticker'] = 1 to indicate that the little ticker should be shown
in the element only for this one view!

In my 'post' element I say:

if ($data['ticker']){
   // show that ticker!!!
}

Problem is that for ALL the other controllers->views I get a 'missing
index' for ticker. So, what I am asking is what is the best php5 /
cake practice for handling this. I would rather not have to define
$data['ticker'] in every other view or anywhere else. Is there a way
to define it in the element and then overwrite it on load (or
something). I am trying to determine the best, most agile practice for
this situation.
