title: How to perform repetitive actions in PureMVC flex application?
body: <p>Currently working on a flex AIR project based on PureMVC framework. There was a new requirement to the project, an operation is to be performed repetitively at regular interval which has some business logic. As per PureMVC this should be placed in the command, but then command would get garbage collected the moment its executed.</p>
  
  <p>Given the scenario there are few doubts/confusions/clarifications...</p>
  
  <ol>
  <li>Creating a command with business logic would be one solution ... but then who would trigger it at specific interval? (shouldn't this be done by a command as per PureMVC)</li>
  <li>Placing the command trigger in a mediator or placing the logic in a mediator (this would make pureMVC a bit impure :) )</li>
  </ol>
  
  <p>How do I find a solution for this kind of scenario?</p>
