JSF: Bean Instantiation

[Gregg Bolinger]

If I have a page as simple as a form with a single text field and a submit button, all done in JSF of course. And then I have a JavaBean for this form. When does this Bean get instantiated? When the form is accessed or when the form is submitted, none of the above?
Thanks.

Hi Greg,
It depends on how its specified in the faces-config.xml
<managed-bean-scope> session </managed-bean-scope>
will put it in the session and it will be created when the bean is first accessed.
Hope this helps...

Well, at what point is the bean first accessed? When I view the form or when I submit the form? And in addition to that, is it my responsibility to remove that Bean from the session if/when I don't need it anymore?

It would appear, after a little testing, that the Bean is accessed the first time when the Form is accessed for the first time since you are specifying a value for the textfield.

Hi Greg,
You got it, when the page renders for the first time...
