I was following the example to implement custom filters in Joomla 2.5 admin component.<\/p>\n

But I am getting error at models populateState<\/code> method:<\/p>\n

\n

Call to undefined method somecompModelsomecomp::getUserStateFromRequest().<\/p>\n<\/blockquote>\n

$app = JFactory::getApplication('administrator');\n\/\/ Load the filter state.\n$search = $this->getUserStateFromRequest($this->context.'.filter.search', 'filter_search');\n<\/code><\/pre>\n
Error disappears if I call getUserStateFromRequest<\/code> using $app<\/code>:<\/p>\n
$app->getUserStateFromRequest($this->context.'.filter.search', 'filter_search');\n<\/code><\/pre>\n
So whats the problem? In default Joomla components I’ve seen that it use the same approach and it works. Maybe I miss something in my model class?<\/p>\n
Any ideas?<\/p>\n
    \n
  1. \n
    This is happened because $app<\/code> is an object of your application class. As you defined it in your code.<\/p>\n
    $app = JFactory::getApplication('administrator');<\/code><\/p>\n
    and getUserStateFromRequest<\/code> method is defind in that Application class.so you have to use it like this if you want to access this method.<\/p>\n
    $app->getUserStateFromRequest($this->context.'.filter.search', 'filter_search');\n<\/code><\/pre>\n
    And for your information $this<\/code> variable is your local object.<\/p>\n<\/li>\n<\/ol>\n
