getUserStateFromRequest issue

[j-guy]

Hi, 

I've got a custom component with a search page that includes simple text filters and multi-select list filters.    The search and pagination work fine when I use a simple text filters like filter_text_search.   The search works with multi-select items as well.   The pagination fails when the multi-select filters are used because the model to retrieve the stored multi-select values.    Any thoughts?

My JModelList::populateState stores the values like below.   

$text_search = $app->getUserStateFromRequest($this->context.'.filter.text_search', 'filter_text_search');

$this->setState('filter.text_search', $text_search);

$array_search = $app->getUserStateFromRequest($this->context .'.filter.array_search', 'filter_array_search');

$this->setState('filter.array_search', $array_search);

I've tested this calling getUserStateFromRequest with $app and $this. Just as a test, I modified my form to return the multi-select filter in a string using the javascript join function.  I was surprised to find it had the same issue.   

 I'm not sure how getStoreId would effect this problem but I tried some variations

                $id.= ':'. serialize($this->getState('filter.array_search'));

$array_search = $this->getState('filter.array_search');

if (is_array($array_search )){

$id.= ':' . implode(',', $array_search );

}

else {

$id.= ':' .  $array_search ;

}
