I've spent too much time on this so far and am wondering if conceptually I am
doing something wrong. I would imagine this to be a fairly common use case for
folks, so here's the issue:
Here's a snippet of my xhtml page -
| <s:decorate template="layout/edit.xhtml">
| <ui:define
name="label">Timeline</ui:define>
| <h:selectOneMenu id="timeline"
value="#{task.selectedTimeline}" required="false"
| immediate="true">
| <f:valueChangeListener
type="com.edwardjones.statusreporting.view.TimelineChangeListener" />
| <s:selectItems id="timelinelst"
value="#{timelineList}"
| var="timeline"
label="#{timeline.description}" />
| <s:convertEntity />
| <a:support event="onchange"
reRender="dt"/>
| </h:selectOneMenu>
| </s:decorate>
|
| <h:inputText id="dt"
|
value="#{selectedTimeline.startDate}">
| <f:convertDateTime pattern="MM/dd/yyyy"/>
| </h:inputText>
|
| <jp:popupCalendar id="date_popup"
| for="date"
| format="MM/dd/yyyy"
| rendered="#{!disabled and
rendered != false}">
| <h:graphicImage url="img/calendar.gif"
| title="Click here to select
date"/>
| </jp:popupCalendar>
|
The TimelineChangeListener is as follows:
| @Name("timelinechange")
| public class TimelineChangeListener implements ValueChangeListener
| {
| @Out(value="selectedTimeline", required = false, scope = SESSION)
| Timeline timeline;
|
| public void processValueChange(ValueChangeEvent arg0)
| throws AbortProcessingException {
| timeline = (Timeline) arg0.getNewValue();
|
| // TODO Auto-generated method stub
| System.out.println("timeline selection");
| }
| }
|
The Timeline entity looks as follows:
| /**
| * Timeline generated by hbm2java
| */
| @Entity
| @Name("timeline")
| @Role(name="selectedTimeline", scope=SESSION)
| @Table(name = "timeline", catalog = "statreport", uniqueConstraints =
@UniqueConstraint(columnNames = "description"))
| public class Timeline implements java.io.Serializable
| {
| private int id;
|
| private String description;
|
| public Timeline()
| {
| }
|
| public Timeline(int id, String description)
| {
| this.id = id;
| this.description = description;
| }
|
| @Id
| @Column(name = "id", unique = true, nullable = false)
| @NotNull
| public int getId()
| {
| return this.id;
| }
|
| public void setId(int id)
| {
| this.id = id;
| }
|
| @Column(name = "description", unique = true, nullable = false, length =
20)
| @NotNull
| @Length(max = 20)
| public String getDescription()
| {
| return this.description;
| }
|
| public void setDescription(String description)
| {
| this.description = description;
| }
|
| @Transient
| public Date getStartDate()
| {
| Calendar startCal = Calendar.getInstance();
| // Determine start of week
| if (getDescription() == null || getDescription().equals("Weekly"))
| {
| System.out.println("Weekly timeline");
| }
| else if ( getDescription().equals("Monthly"))
| {
| System.out.println("Monthly timeline");
| }
| // Convert calender to date
| Date startDate = startCal.getTime();
| return startDate;
| }
|
| @Transient
| public Date getEndDate()
| {
| Calendar startCal = Calendar.getInstance();
| if (getDescription() == null || getDescription().equals("Weekly"))
| {
| ...........
| }
| return endDate;
| }
| }
|
|
The ajax support tag calls the timelinechangelistener which sets the selected
timeline and puts it into a session scope. Since the rendered element calls the
selected timeline getStartDate method, I expected the selected timeline to get
passed in, however the timeline on which the getStartDate is called is never
selectedTimeline. Hopefully, made things clear as to what I am trying to
accomplish. In short, based on the selected timeline, I would like to change
the start date/end date logic.
Any help is appreciated....
Thanks
