[Opensource] explain the problem with addparam

[Ali Ghadiri]

I have a state in which I make a query by the form fields I got from a form in previous state, this state shows some of the outputs ( due to the query it makes) and then it shows a button which transfers user again to this state (same state)  but with different query just like a loop.(to show the rest of output). So I want to transfer my response to this state when user clicks for it. Because I need some of the form fields when I come back to this state again but this time I don't have the form fields. How can I get them?(I added them to my request and it worked but I still have problem in getting one of my parameters which I adds each time I come to this state. I decreases its length but it didn't work.) Any idea? Thanks

And you don't want to use hidden fields? if you are just forwarding a request from one state to another within the same HTTP call, you can use setFormCache(). carrying information between client-requested states gets a little trickier, with hidden field being the cleanest method, and using the persistent session possible also.

I want to have them when I come back to this state and I don’t want to add all of them (there are so many) to my request object. How can I do that in other ways? (It would be better if I don’t have to add another state.)
