Subject Re: Why do we need the set/push tag?
Date Thu, 06 Jan 2011 14:26:39 GMT
Generally speaking, when you use a struts tag and you do NOT specify
an object, the tag will default to using the object at the top of the
stack. The push tag lets you force a specific object to be at the top
of the stack, so you can write generic, reusable jsp code (like
fragments, etc.) that doesn't reference the object name directly and
instead operates only on its generic properties.
