Hi
thank you for reading my post.
Is there any difference between binding using a Managed bean (defined in 
faces-config.xml) and an object
defined in backing bean class ?
in a tutorial i saw that author used a Managed beans to accomplish some 
jobs.
he referenced to a Managed beans by using #{Bean1.ts}
i tried and made ts in my backing bean and referenced ts like : #{page12.ts}

what is difference between this two approach.
