multiple select: pulling from the database and populating the sel ect listbox in a form with multiple selections

[Joel Schmidt <Jo...@apexlearning.com>]

I've looked through the mail list but still don't quite get it.
I'm working on a form that can create or edit a particular role and it's
functions I want to (in create mode) select multiple functions and then in
edit mode display those multiple functions selected in a multiple select
listbox. Do I need a separate bean for the array that holds the particular
selections of the edited role? Do I need an iterate tag of some sort? I'm
able to populate my list box with only the first item in the array from my
action. Using println I can see that I populated my array with the data I'm
looking for.
I have in my jsp

java.util.ArrayList list = new java.util.ArrayList();
    FunctionData[] allFunctions = (FunctionData[])
session.getAttribute("allFunctions");
				for(int k = 0;k< allFunctions.length;k++)
				
				{
                    list.add(new
apex.ace.web.actions.LabelValueBean(allFunctions[k].getName(),allFunctions[k
].getPK().toString()));
                }
   
    pageContext.setAttribute("serverTypes",list);


<html:select property="type" size="16" name="SubmitRoleForm"
multiple="true"> 		
 		            <html:options collection="serverTypes"
name="label" Property="value" labelProperty="label"/> 		
 		            </html:select>
In my formbean
I have getType() and setType() for String[] type

in the my action I have 

String[] type = new String[role.getFunctions().size()];
	                    int i = 0;
	                    Iterator it =
role.getFunctions().values().iterator(); 
				        while(it.hasNext())
				        {
				            type[i] =
it.next().toString().substring(21);
				            i++; 
				        }
	                    for (int j = 0;j< type.length;j++){
	                     System.out.println(type[j]);   
	                    }
	                    
                        // Populate the subscription form

	                    if (form == null)
	                    {
                            if (servlet.getDebug() >= 1)
                                servlet.log(" Creating new Form bean under
key "
                                    + mapping.getAttribute());
	                        form = new SubmitRoleForm();
                    
                            session.setAttribute("SubmitRoleForm", form); 
	               
	                        SubmitRoleForm subform = (SubmitRoleForm)
form;
                               
                                subform.setRoleEdited(roleEdited);  
                                subform.setAction(action);
                                subform.setName(name);
                                subform.setKey(key);
                                subform.setType(type);
