Re: make invisible if model object is null
Alright, this is my last try replying with MS Outlook. =) And I will also add
more info to help with this thread.
You can use borders to acomplish what you want. Here's an example:
#JAVA
public abstract class ConditionalHiddenBorder extends Border {
public ConditionalHiddenBorder(String id) {
super(id);
}
public abstract boolean isVisible();
}
#HTML
html
body
wicket:border
wicket:body/
/wicket:border
/body
/html
#EXAMPLE (Wicket's Quickstart)
public HomePage() {
final Label label = new Label(message, If you see this message wicket
is properly configured and running);
ConditionalHiddenBorder chb = new ConditionalHiddenBorder(border) {
public boolean isVisible() {
return label.getDefaultModelObject() != null;
}
};
chb.add(label);
add(chb);
}
#HTML Example
div wicket:id=border
span wicket:id=messagemessage will be here/span
/div
Hope this reply works!
cheers,
Bruno

Subject: make invisible if model object is null
I use the next construction very often:
[markup]
wicket:enclosure child=something
pSomething here, description, comments etc: span
wicket:id=somethinig/span/p
/wicket:enclosure
[java]
add(new Label(something)
{
@Override
public boolean isVisible() {
return super.isVisible() getDefaultModelObject() != null;
}
});
And there are a lot different components which should be hidden with
some arounding text if they have null value of model object.
How to make this more elegant?
First obvious way - inherit from Label, and make something
LabelInvisibleNull, but it is very bad, because a lot different
components (not only Label, but Image, WebMarkupContainer, some my
custom components, etc) require this behavior.
Second - more meaningful - make a IBehavior. But it doesn't work. In
bind is to early to check model, but in beforeRender is too late
to change visibility.
Is there any other option?

Re: make invisible if model object is null
we should add ibehavior.isVisibilityAllowed(Component) or something
like that for 1.5 release. feel free to create a jira issue.
