Hello Aishu,

I guess the bean is executed to process submitted data. There's not enough information to say more.

I have the same question as Aishu. The setter/getter method will executed many times, if it is go to a ui:component or leave it. e.g. A wizard is implemented with modalPanel. Along steps, there is a combbox in the modalPanel, the setter/getter methods of the components h:selectOneMenu and f:selectItems will executed by enter or leave the step. I guess, that the reason is, there are manny ajax component as well as e.g js:function.

You can use PhaseTracker to check on what lifecycle phases the methods are accessed.
