I'm sure this must be fairly trivial but I can't seem to get it to work (too late
in the day I think :) ). I want to link the value of a radio button set to a value in a
foreign table. The problem I seem to be having is that initially there is no value set so
there is no corresponding row in the table. I want completing the radio button (then
clicking on a save button) to create the row in the table.
My page code is thus:
<h:column>
| <f:facet name="header">Performance</f:facet>
| <h:selectOneRadio value="#{staffBooking.staffFeedback.rating}">
| <f:selectItem itemValue="4" itemLabel="Excellent"/>
| <f:selectItem itemValue="3" itemLabel="Good"/>
| <f:selectItem itemValue="2" itemLabel="Average"/>
| <f:selectItem itemValue="1" itemLabel="Bad"/>
| </h:selectOneRadio>
| </h:column>
and my entity bean code is:
@Entity
| @Table(name = "`Staff Bookings`")
| public class StaffBooking implements Serializable
| {
|
| ...
|
| @OneToMany(mappedBy="staffBooking")
| private List<StaffFeedback> staffFeedback = new
ArrayList<StaffFeedback>();
|
| ...
|
| public List<StaffFeedback> getStaffFeedback()
| {
| return staffFeedback;
| }
and
@Entity
| @Table(name = "tblStaffFeedbackRating")
| public class StaffFeedback implements Serializable
| {
|
| ...
|
| @ManyToOne
| @JoinColumn(name="StaffBookingsUID")
| private StaffBooking staffBooking;
|
| ...
|
| public Byte getRating()
| {
| return rating;
| }
but when I try to view the page I get:
