Well, you don't have to use session scope and you can clear Collection in
reset() method.
registration.jsp:
<logic:iterate id="item" name="allRoles">
<html:multibox name="registrationForm" property="selectedRoles">
<bean:write name="item" property="value"/>
</html:multibox>
<bean:write name="item" property="label"/>
</logic:iterate>
struts-config.xml:
<action path="/editUser"
type="com.name.wos.struts.userAdm.EditRegistrationAction"
name="registrationForm"
scope="request"
validate="false"
parameter="editUser">
<forward name="success" path="/registration.jsp"/>
</action>
registrationForm.java
public String[] getSelectedRoles() {
return this.selectedRoles;
}
public void setSelectedRoles(String[] selectedRoles) {
this.selectedRoles = selectedRoles;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
String [] arrUserRoles={};
this.setSelectedRoles(arrUserRoles);
}
In registrationAction - just populate selectedRoles array with "checked"
values from DB.
Populate Vector allRoles with all user Roles and put it into context:
RolesVO curElement;
RolesBD rolesBD = new RolesBD();
Enumeration tempAllRoles = rolesBD.selectAllRoles().elements();
Vector allRoles=new Vector();
while (tempAllRoles.hasMoreElements()) {
curElement = (RolesVO)tempAllRoles.nextElement();
allRoles.addElement(new
LabelValueBean(curElement.getRoleName(),curElement.getRoleId().toString()));
}
application.setAttribute("allRoles", allRoles);
