You use a bean for doing things with a single instance of something. With a
single user. wIth a single form submission. WIth groups of records (or
'objects' we really should say because it's not always records out of a
database we're dealing with) the are arrays, structs, queries etc which is
more of what you are used to doing.
For example in my CMS, when i need to display a page. I create a bean
("instantiate" is the jargon term for it) containing the specs of the page
- the page title, the next url and title up in the hierarchy (for making the
breadcrumb), the access level required to view the page, the teaser text,
whether it has sidebars, image name, stuff like that for the page, because
it's only one page i am dealing with right now. And also I make a query
object (using the PagesDAO cfc) containing all the details of the pages
underneath this one, for the navigation around the page, or the 'related
links' section of the page. and another query containing the actual content
- the paragraphs of text or the images in the image gallery etc.
Beans are for dealing with one single instance of an object. If you're
dealing with groups of things, you're in much more familiar territory with
lists, arrays, structs and queries.
