Hi,
In my form I have employee number, name, and roles, here employee number
and name are text fields and roles is a checkboxlist, to generate the list
boxes i had a map called rolesMap in my action class, as well i have a set
called userRoles that specifies the items to be selected.
*jsp*
<s:checkboxlist key="roles" list="rolesMap" value="userRoles"
name="userRoles" />
*action class*
public Set<Long> getUserRoles() {
return userRoles;
}
@RequiredFieldValidator(type=ValidatorType.SIMPLE,fieldName="userRoles",message="",key="requiredstring")
public void setUserRoles(Set<Long> userRoles) {
this.userRoles = userRoles;
}
public Map<Long, String> getRolesMap() {
generateRoles();
return rolesMap;
}
public void setRolesMap(Map<Long, String> rolesMap) {
this.rolesMap = rolesMap;
}
private generateRoles(){

}
it is coming fine when i generate the form, but when i submit the form it is
throwing exception....
