Why do we need the set/push tag?

2011-01-06 Thread maven apache
Hi I am learning the struts tag,however I can't understand why we need the set/push/bean tag? In my opinion,the views like jsp just need to pull data from the Actioncontext and render them.

Another approach would be to store a request-id in the form and session and compare this values. On Browser navigation, e.g. reload, browser would sent an old request-id. To be sure you have to combine the two techniques (Post/Redirect + Request-id). -

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 does

Stefan, Can you filter the list somehow? Say, if the list entries fall into categories, have the user select a category first. Something like that would probably help. -Brian On Thu, Jan 6, 2011 at 6:36 AM, Dave Newton wrote: > It's all html; if one of the S2 tags doesnt do what you want
