Hello all,
This is my first wicket message, so first of all, I would like to
gongrats the whole team for the great job !
Now, my problem :
I have created a NewFeedbackPanel which extends FeedbackPanel and
override OnBeforeRender(). This NewFeedbackPanel is created into a
class and added to a target :
final NewFeedbackPanel indicator = new NewFeedbackPanel("indicator",
30000, true);
final NewAjaxButton link = new NewAjaxButton(DOWNLOAD_NEW, new
ResourceModel("preferences.downloadNew"))
{
@Override
public void onClick(AjaxRequestTarget target)
{
..........
// log successful message and refresh target feedback
this.info(getLocalizer().getString("preferences.downloadSuccess", this));
target.addComponent(indicator);
target.addComponent(PhoneDetails.this);
}
};
add(link);
add(indicator);
When I test, i can't see any feedback, and the method OnBeforeRender()
of the class NewFeedbackPanel is never called.
Any idea ?
Thanks,
jb
Code for NewFeedbackPanel.java :
public class NewFeedbackPanel extends FeedbackPanel
{
private static final int DEFAULT_TIME = 1000;
private boolean _blocker;
private int _displayTime;
public NewFeedbackPanel(String id)
{
this(id, DEFAULT_TIME, false);
}
public NewFeedbackPanel(String id, int displayTime)
{
this(id, displayTime, false);
}
public NewFeedbackPanel(String id, int displayTime, boolean blocker)
{
super(id);
_blocker = blocker;
setOutputMarkupPlaceholderTag(true);
add(HeaderContributor.forCss(NewFeedbackPanel.class,
"feedback.css"));
setVisible(false);
Here, you feedback is set as not visible. If you take a look into
Component#internalBeforeRender, you can see that a not visible component
never call onBeforeRender method.
So you need to override Component#callOnBeforeRenderIfNotVisible to
return true in order to evaluate you code in onBeforeRender
_displayTime = displayTime > 0 ? displayTime : DEFAULT_TIME;
if (_blocker)
{
add(new AttributeAppender("class", new Model("hidder"), "
"));
}
}
@Override
protected void onBeforeRender()
{
super.onBeforeRender();
IRequestTarget target = RequestCycle.get().getRequestTarget();
if (anyMessage())
{
if (target instanceof AjaxRequestTarget)
{
String javascript =
"window.setTimeout(function(){window.document.getElementById('" +
getMarkupId()
+ "').style.display = 'none'}, " +
_displayTime + ");";
((AjaxRequestTarget)
target).appendJavascript(javascript);
}
}
else
{
setVisible(false);
}
}
}
