When to pass object instance /class type?
Hey,
What is the difference between:
setResponsePage(CoolPage.class)
and
setResponsePage(new CoolPage())
?
When to use each one?
Thanks.

That is incorrect. You can pass data to your CoolPage regardless of the
setResponsePage() method signature. Just try implementing both and observe
the URL once you invoke both its signatures. One will be bookmarkable and
the other will not be but I'll leave it to you which signature is
bookmarkable. Once you have explored this, investigate PageParameters,
WebApplication's mountBookmarkablePage method then URL Coding strategies.
Oh, make sure you have either a default constructor or a constructor passing
in a PageParameters in your CoolPage before playing around with the
setResponsePage(Class pageClass) signature. ;-)
Best,
James.

We call setResponsePage(new CoolPage()) if want to pass some data to CoolPage
and we call setResponsePage(CoolPage.class) if we only want to render
CoolPage
Am I right?
