Hi,
Following on from other questions on this issue.
Suppose I have a form and one of the fields is best populated from a
list which is held server side. So I have a button next to the field
which navigates to a new form which shows the list (maybe a list of
images, for example) and allows a selection to be made. Before I
transfer to the list I store the calling page name in some state
container so I know where to come back to when the selection has been
made. But what about the others fields that may already have been keyed
in up to now in my original data form. Should I store all these values
too? Is there a way to save the state of the form before the transfer
and reinstate them easily?
Sorry if this is a basic question. Any examples from tutorials would be
appreciated. I have looked but I guess I don't even know how this
problem /techniques is officially described.
Cheers
