I've been given the task to program an use case's flow with only two
JSPs to be exhibited upon the auspices of a controller and, 'til now,
I´ve got nothing but a headache.
As the command I have a POJO (got from a DAO) associated
bidirectionaly with another one whose contents are supposed to be
initialized and edited by a "fill-visualize-alter" sequence of steps
within the offending flow.
The problem arises in the "alter" step, in which the flow is
redirected to the initial JSP - the very one I had used to fill in the
inputs binded to the properties of the associated object. I ain't been
able to access the contents of the just initialized object, albeit I
do can access the properties of the one obtained from the DAO.
I overheard someone saying in other posts that there are two ways to
tackle the problem:
1. One might use hidden inputs in the JSP whose controls are not
binded to the command as a maneuver to force Spring to keep the
reference to that object, or
2. One can control the flow with an instance a subclass of
AbstractCommandController with its sessionForm attribute set to
I´m still not convinced that the first sugestion is a good way to
handle the problem, although it solved the puzzle; whereas the second
doesn´t seem to work as I'd like it to.
Anyway, thanks in advance!
