Hi,
when I want to manage the 'before' and 'complete' handlers of an ajax
component, everything works as expected if I override the component
updateAjaxAttributes method of the component like in the below example:
public class HomePage extends WebPage {
public HomePage(final PageParameters parameters) {
super(parameters);
final AjaxLink<String> link = new
AjaxLink<String>("submit",Model.of("link"))
{
@Override
public void onClick(AjaxRequestTarget target)
{
}
@Override
protected void
updateAjaxAttributes(AjaxRequestAttributes attributes)
{
super.updateAjaxAttributes(attributes);
IAjaxCallListener listener = new
IAjaxCallListener()
{
@Override
public CharSequence
getBeforeHandler(Component component)
{
return "alert('Before');";
}
...
@Override
public CharSequence
getCompleteHandler(Component component)
{
return "alert('Complete');";
}
};
attributes.getAjaxCallListeners().add(listener);
}
};
add(link);
}
}
on the other hand, if I create an AbstractDefaultAjaxBehavior, override
updateAjaxAttributes, and attach it to the component, the two handlers are
not invoked:
public class HomePage extends WebPage {
public HomePage(final PageParameters parameters) {
super(parameters);
final AjaxLink<String> link = new
AjaxLink<String>("submit",Model.of("link"))
{
@Override
public void onClick(AjaxRequestTarget target)
{
}
};
link.add(new SomeAjaxBehavior());
add(link);
}
}
// SomeSomeAjaxBehavior
public class SomeAjaxBehavior extends AbstractDefaultAjaxBehavior
{
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes attributes)
{
// TODO Auto-generated method stub
super.updateAjaxAttributes(attributes);
IAjaxCallListener listener = new IAjaxCallListener()
{
@Override
public CharSequence getBeforeHandler(Component
component)
{
return "alert('Before');";
}
...
@Override
public CharSequence getCompleteHandler(Component
component)
{
return "alert('Complete');";
}
};
attributes.getAjaxCallListeners().add(listener);
}
@Override
protected void respond(AjaxRequestTarget target)
{
}
}
am I missing something or this is a bug?
Thanks
