I'm not especially keen dispatch actions . Just this business of using links and the request being cleared leaves me scoping to session and using a link, again i'm not that against scoping to session but I thought someone in the anti httpsession brigade would have a solution for this common problem.
I don't think I'm tree-barking but ruminating on dispatch action (although i'm not certain).
I'm trying various ways and seeing what happens. But indexed handler parameters seem like the sort of thing that would be required to do such a thing, but seem to be more the consequence of a crack induced state of derangement than something that struts supports.

Mark,
Seems to me you have already worked out the solution, except why do you need
a lookup dispatch action - rather than a "roll your own" - you have two
methods right - "Move Up" and "Move Down"?
Your jsp will populate a (foo?) List with either "Move Up" or "Move Down"
(depending on the button pressed) in the appropriate index position - so you
loop through them until you find a none null entry and call the appropriate
method depending on the value with the index position you're at.
trying to use look up dispatch action seems to be overly complicating things
to me.

I was wondering if anyone has found any slick, no javascript dependent
solution to the following situation. My question in short is, is there
a way of having an indexed dispatch action, or have i been on the crack
again?
I have a form of nested beans which are ordered according to a position
stored in the model. I don't do any sorting in the web tier nor do i
want to, other than rejigging the indices of some indexed properties
until such a time as the user is ready to save his/her changes to the
model.
<form name="foosForm" action="/myapp/save.do"> <input type="text" name="foo[0].name"> <input type="text" name="foo[1].name"> <input type="text" name="foo[2].name"> </form>
Now when i save I'll save the index as a field called position, thus all that's fine and dandy.
So lets say I want the use to define the position by having a move up and move down, but rather than using an indexed link i want to use a button.
I've a lookup dispatch action with a moveup method and all that jazz.
<html:form action="/save.do"> <logic:iterate id="foo" name="foosForm" property="foos"> <html:text name="foo" property="name" indexed="true" /> <html:submit property="method" indexed="true"> <bean:message key="button.moveup" /> </html:submit> </logic:iterate> </html:form>
So the rendered html would like like this
<form name="foosForm" action="/myapp/save.do"> <input type="text" name="foo[0].name"><input type="submit" name="method[0]" value="Move Up"> //and so on </form>
Of course if i submit this to a lookupdispatch action, its gonna call me a crazy fool. So i need to have some means of having an indexed map key in my key method map, or something to cross the same bridge i'm trying to cross.
Any ideas? I know i can do this in javascript which i will once i get things running without it, please no javascript suggestions.
