On JSF Page load UI components loading sequence

Question

Hi All,
I have some questions about the UI components loading sequence on the JSF page load.
When a JSF page loads it loads its UI components which have a sequence of getters and setters declared in the backing bean of that jspx page.
Qustion 1: How these getters and setters in backing bean work in loading the jspx page?
Question 2: How this backing bean is related to the Page Definition file for the page loading?
Question 3 (main query): What is the sequence of the getters and setters. Means, if i drop 3 UI components, 1 input text, then a command button and then an output text, then they are accordingly declared in backing bean. On page load first i/p texts getter gets called, then setter, then command button's and theno/p texts, in these sequence.
But can i manipulate their sequence of loading. If yes then how it can be possible?

Answer 1

Answer 1: Getters and Setters in bean normally will be bounded to ui component's properties in jspx page, when jspx page loads these getters get called through introspection and setters gets called when a request is submitted.
Answer 2: Backing bean and page definition are two different entities and they are no way related unless you have a data control for the backing bean and have bindings for those methods in page definition file
Answer 3: The sequence of getters and setters depends on the order of the components they bounded to in jspx page. components in jsf page gets loaded from top to bottom so the getter bound to the top component gets called first and the getter bound to bottom component gets called last.
The only way to change the sequence of getter methods getting called is to just change the order of the components they bound to in jspx page.
Usually, it is not suggested to put business logic inside getters and setters, where you have action and actionlisteners for the same. If you follow that, you don't need to worry of the sequence of getters and setters execution
