title: Calling an Oracle function via Ajax for on-the-spot validation purposes in Oracle APEX v4.2.2
body: <p>I am using Oracle 11g with Oracle Apex v4.2.2 and I was wondering how the best way to call an Oracle function via an ajax call, within a Dynamic Action.</p>
  
  <p>I basically have a function that takes six parameters that either returns the result of 'INVALID' or 'VALID'.</p>
  
  <p>Within my page, I want to be able to accept the values that the user has entered and once they press the button to process, I need to check via ajax whether the result was 'INVALID' or 'VALID' and immediately present the user with a dialog box notifying them that there was an error.</p>
  
  <p>Is there a new means of processing this type of ajax request to call a function, within Oracle APEX v4.2.2?</p>
