Label with AjaxSelfUpdatingTimerBehavior not refreshing
I'm trying something very simple ... I have a form with many panels and in
one of those panels, I want the current date and time to be refreshed
periodically.
final Label msgStatutTransfert = new Label("msgStatutTransfert", new
Date().toString());
msgStatutTransfert.setOutputMarkupId(true);
msgStatutTransfert.add(new
AjaxSelfUpdatingTimerBehavior(Duration.seconds(5)));
frmInfosTransfert.add(msgStatutTransfert); // one of my panels
When the page loads, it puts the current date in the label but then it
doesn't reshesh ... I looked at the debug info ... here's what I get
<?xml version="1.0" encoding="UTF-8"?><ajax-response><component

So far we're even on beers purchased - so I guess not enough! I'm thinking
about adding "Buy Wicket in Action" to my signature to help reduce my
chances of carpal tunnel.

Re: Label with AjaxSelfUpdatingTimerBehavior not refreshing

The problem is not just about understanding models. It's deeper than that.
You have to understand that Wicket architecture is -hardly-speaking- like
Java Swing. Objects that you create, will live just like a JButton, JPanel,
whatever.
Label msgStatutTransfert = new Label("msgStatutTransfert", new
Date().toString());
Here, you create a Label object, and you want an Ajax Update Event to change
the date. Well, that will never happen, because in nowhere you are actually
updating the 'msgStatusTransfert' object's value. It was created containing
an instance of a String (imutable object) from the toString() method of a
Date instance.
Being more specific (like Swing):
Imagine that you create an instance of JButton(new Date().toString()); and
add that to a JFrame. Will that value update by itself after calling
myJFrame.repaint();? No. Only if you override the repaint() method and
before calling super.repaint(), you code something like
myButton.setValue(new Date().toString());
Understand that, and you will easily - and hopefully quickly - understand
why we use Models.
Have fun with Wicket!

Re: Label with AjaxSelfUpdatingTimerBehavior not refreshing
Posted by a_godin <al...@omhm.qc.ca>.
Ok thank you, that worked fine ...
Now, in another panel, I'm trying to show the user the progress that's being
made while a process is running, something like "Job 1 out of 7 running"
then ""Job 2 out of 7 running", etc.
Here's what I did (based on what I read in the link you gave me) :
- Create a simple POJO class JobStatus
- declare a label with an AjaxSelfUpdatingTimerBehavior in my panel
final Label msgStatus = new Label("msgStatus", new
PropertyModel(jobStatus, "status"));
msgStatus.setOutputMarkupId(true);
frmStatus.add(msgStatus);
msgStatus.add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(1)));
- in the onSubmit code of the button that submits the job in the panel
jobStatus.setStatus("Job 1 out of 7 running"); then a little further
jobStatus.setStatus("Job 2 out of 7 running"); etc.
The status is not updated on screen ... any idea what I'a forgetting this
time ?

Yes - you're not understanding models. You created a Label with a static
String - the current time at the time of creation. You need to use a model,
which is a "data finder".... something like:
new Label("msgStatutTransfert", new AbstractReadOnlyModel<Date>() {
public Date getObject() {
return new Date();
}
});
