It is good when used with WM because you can stuff it into the context and then just call it to generate the HTML. It can be used in other cases as well, but WM is the best case for it right now. <p>For example code showing the usage for this module, please see the toString() method below to see how it would be refered to from WM. <pre> // get the roles for a user RoleSet userRoles = new DefaultAccessControl().getRoles(loginid, null); if ( userRoles != null ) { context.put("hasRoleSet", Boolean.TRUE); // get an array of the users roles Role[] usersRoles = userRoles.getRolesArray(); // get an array of all the roles in the system Role[] allRoles = ((RoleSet)RolePeer.retrieveSet()).getRolesArray(); Object[] names = new Object[allRoles.length]; Object[] values = new Object[allRoles.length]; for ( int i=0;i<allRoles.length; i++ ) { names[i] = new Integer(allRoles[i].getPrimaryKey()).toString(); values[i] = allRoles[i].getName(); } SelectorBox sb = new SelectorBox("roleSetBox", names, values); sb.buildBooleans(usersRoles, allRoles); context.put("roleSetBox", sb); } else { context.put("hasRoleSet", Boolean.FALSE); } </pre><P><DL><DT><B>Version: </B><DD>$Id: SelectorBox.java,v 1.2 2002/07/11 16:53:20 mpoeschl Exp $</DD><DT><B>Author: </B><DD><a href="mailto:jon@latchkey.com">Jon S.
