What happens if a before trigger action forces a workflow rule and that causes the trigger event again

Question

Please explain if a trigger event which causes a workflow rule to fire and the goes in a loop. or will it terminate after some update?

Answer 1

This is covered in the documentation on the order of execution.

Salesforce has thought of this, and has put safeguards in place to prevent infinite loops.

If a workflow rule on an object, call it ObjectA, has a field update (also on ObjectA, for sake of ease), it will cause the before update and after update triggers for ObjectA to fire precisely one more time.
