title: symfony - calling an action from another action
body: <p>i have two different actions in two different modules, and i need to execute one of them inside the other.</p>
  
  <p>consider the following actions:</p>
  
  <pre><code>//first module
  class module1Actions extends sfActions {
  
       protected function function1Form(sfWebRequest $request, sfForm $form) {
         //i need to call a function from module2 in here to do sth but i don't need any view to be returned.
         //but i need some variables to be returned by the second action
       }
  }
  
  //second module
  class module2Actions extends sfActions {
  
       protected function executeSth(sfWebRequest $request, sfForm $form) {
         //Do Something in here and return some values.
       }
  }
  </code></pre>
  
  <p>as i said i need to execute an action and get some values from it but i don't know how to call it. it's in a different module . can i access it ? how? and how i get the values back?</p>
  
  <p>thanks.</p>
