Dear Friends, 

Need your help, My Question is...

There is a Trigger Code on Task object, Which is going to update a custom field on Opporunity (There is DML Update operation on Task Object for Opportunity). And there is also a trigger code on Opportunity (after Update). So Whenever i create a task, and i am comparing (Task.WhatId==Opp.WhatID), In the Console it is saying that ' Attempt to Derefernce a null Object ',. How to over come on this. How to use Recursive trigger here. Please help me on this. Thank you.
