How do alternatives to JSF like Struts, Struts2, and others handle the concept of view state?
For the most part, they don't have the concept of View State. If a control uses data that is not in the post, and the page needs to be presented again (because, say, validation failed), then an action-based framework will go and fetch the control data again. (In fact, Struts 2 has a special "prepare" method that is used to create (or recreate) "View State".) If the data in question is semi-static (a drop down list), and the query is cached, then it's a memory-to-memory transfer, otherwise, we have to hit the database again. The trade-off having JSF automatically process the encoded view state field (whether you need it again or not). -Ted.
