I guess conceptually I'm just not understanding how this can work.
For presentation what I would ideally like is:
[X]Permission NamePermission Description
[ ]Permission NamePermission Description
Where each permission name is unique, the checkbox could be turned on or off
depending on a variable linked to the permission name, and also a permission
description.
So on the display page there would need to be some kind of iterator that
iterates through the list of permissions, creating a checkbox with the
parameter being the permission name and its value being on or off, the
permissions name in a text field, and also a permission description text
field.
I have classes built that represent a permission and a user, and classes
extending vector that hold a list of users and permissions. The user class
can retrieve a list of the permissions it has. The permissions class can
goto the database and make a vector containing permission elements to
represent all the permissions that are capable on the server.
Anyway I guess I am having a really hard time designing the form in such a
way that something can be iterateable in it, probably the permission name,
but also be able to get/store the permission name, description, and if the
user has it or not.
Sorry if im not more clear... been sitting here for around 3 hours trying to
figure out how to even start attacking this and ive read a lot but am
drawing a blank.
Thanks a ton in advance..

Subject: Re: Dynamic Form help
You use indexed property.
html:text property=permission indexed=true /
This stuff i quite well documented, what isn't well documented is how
to dynamically change the length of an indexed property. I've been
using ArrayList for this..
form-property name=permission type=java.util.ArrayList /
You'll need to scope you form to session, as you get null pointers all
over the show.
ArrayList myList = new ArrayList();
while(myObject.hasMoreStuff()) {
myList.add(myObject.next())'
}
theForm.set(permission, myList);
//also put the arraylist in an available context.
request.setAttribute(permissions, myList.toArray());
//jsp
logic:iterate id=perm name=permissions
html:text name=perm property=deleteUser indexed=true /
/logic:iterate
I'm still working on how to store the properties in the form when the
size of the form property is changed. But I think this approach with
solve what you're doing.

I'm developing some administrative functions for our web app,

I'm trying to decide the best way to go about it, becaues the
permissions
are pulled from a database and so they could change everytime the page
is
loaded, and obviously every user will have different permissions which
need
to be checked.
It shouldnt be a problem to iterate through a list of permissions, but
the
question I have is when I go to submit a the form to modify the users
permissions, the names of each checkbox (permission) will change, so
how
would I develop a form to handle that? And is there an easy way to
populate
all the checkboxes when the page loads?
I'm using JSP's to handle it.. would love to use struts html:XXX
tags if
possible.
Reccomendations welcome =)
Thanks
