Method not found in class e.g. Doctrine DBAL

Hi
I am getting Method not found errors when using Silex in PHPStorm. This is primarily
occurring fro Class methods where an instance of the class is accessed from a closure
or stored in an appliaction variable.

For example $app['db'] references an instance of the Doctrine DBAL connection.

If I use $app['db']->prepare($sql); in my code the call to prepare is flagged as
Method not found in class.  Is there a way to make PHPStorm recognize that "prepare()"
is a method of the Doctrine DBAL. I have tried including use statements for  the
Silex DoctrineServiceProvider and Doctrine DBAL classes but the classes remain greyed out
in the use statement.
