Re: Need Ideas for This Puzzle
There are at least two good solutions. I like the second one best. 1. Tag Conditional Logic Solution Just use the c:if, c:choose and c:when tags. I assume, Caroline, that you are using JSTL. If not, then there are equivalent solutions with Struts logic tags. 2 Action Conditional Delivery Solution Or, you can read the role of the user going into the Action that forwards to the response object displaying the options and only deliver the options appropriate to the role of the user.

As a third alternative, rather than do everything on conditional tags in your jsp I would probably opt for either an addional bean or additional properties in your ActionForm that is contains methods such as isGroupADisplayed() etc etc and set the properties in your Action that loads the form.

RE: Need Ideas for This Puzzle
Here's my idea: Create a bean that has multiple Boolean fields, with each corresponding to a checkbox you might want to display. In the action that loads data for this page, process the user's role and set the bean's Boolean values accordingly. Store the bean so that the jsp can read it. For all the checkboxes, the jsp will read the bean and display only the checkboxes that have a corresponding true value. In the action that saves the data from this page, process only those checkboxes that were displayed.

RE: Need Ideas for This Puzzle
What about something like:
%
boolean checked = isChecked(a); // check if the
value should be checked by default
if(showCheckbox(user, a)) { // check if, for this
user, the checkbox should be visible
%
input type=checkbox name=a value=a %= checked
?checked: %
%
} else { // show disabled checkbox (or leave that out
to show nothing...)
%
input type=checkbox name=noname %= checked ?
checked : % disabled=diabled /
%
if(checked) { // don't need hidden value if default
is unchecked
%
input type=hidden name=a value=a
%
}
}

Re: Need Ideas for This Puzzle
Hi, Caroline, Just a little follow up to all these good suggestions. I agree that if you use the Action, then you should definitely use helper classes and hopefully decouple them from the action. I like to use multithreading in the helper classes generally. The suggestions about using the ActionForm instead are also good. I guess to decide whether you want to go with Action or ActionForm should depend on whether your logic makes the choice of roles one of presentation or one of buisness logic. I think it could go either way. Definitely these are two different approaches.

RE: Need Ideas for This Puzzle
Keeping the unused fields around as hidden fields is a good idea. It will
keep your 'select all' javascript from getting complicated.
Just make sure that your action doesn't process any of the fields that were
made hidden, because hackers could modify those hidden fields manually
before sending back the response.
