When i click once on a button called save , the process done in the flow from baseAction till the DAO, it is all twice. i.e if i have something like a system.out.println("hello") in the DAO with no loop. Hello is getting printed twice in my console , also we checked it with a static count variable as and when the control enters the action class. The count value is 2 for a single submission. But this functionality works fine on my colleagues machine. everything being same configuration .Unable to understand as to what the problem might be. Any Help will be appreciated on this.
