Updating computed field's value without needing to clear cache I have a computed field that lists content related to a node, so it's value should be changed when I add a new node. Whenever, I add a new node I need to clear the cache to update the computed field's value.

How do I prevent caching value of the computed field OR re-compute the value after adding a new node?
Check out the rules module (http://drupal.org/project/rules):


  The Rules module allows site administrators to define conditionally
  executed actions based on occurring events (known as reactive or ECA
  rules).


You could add a rule to clear the cache whenever a new nodes has been added. 

It's not exactly the way you asked for, but it gets the job done - updating the computed field's value whenever a new node has been created.
