[Webwork-user] Putting things in the session

[Peter K. <pe...@mo...>]

This could be an answer in some sort of FAQ:

How do I take an int from the item on top of the value stack and put
it in the user's session to be retrieved later ?

The problem I'm trying to solve is getting values from a number of
controls in a list which all have different names. I can get the
values using the map but I need to know what they are called. I have
used a name stem and a numeric suffix for each control hence the need
to know the number of controls present.

I guess I could use a hidden field on the JSP but this seems wrong
somehow. Putting the value in the session before displaying the JSP
leads to complications when the users play around with the back
button on the browser or direct URL references.

Any ideas ?
