Hi,
WebMarkupContainer container = new WebMarkupContainer("container", new
CompoundPropertyModel(new ProfileModel(userId)));
add(container);
container.add(new Label("firstName") {
protected boolean isVisible() {
return !Strings.isEmpty(getModelObjectAsString());
}
});
The label will have a model inherited from the CompoundPropertyModel.

Hello Igor,
If I am using a PropertyModel for my Label,
new VisibleLabel("firstName", new PropertyModel(new ProfileModel(userId),
"firstName"))
then visibleLabel.getModelObjectAsString() returns the right value for the
"firstName"
property. The Model is the wrapper for the firstName value.
But if I want to use the CompoundPropertyModel then the method returns
nothing.
There is no Model that directly wraps my firstName value, right? The Model
is associated
with "all" the Labels not only with one.
I cannot figure out how to use it with the CompountPropertyModel (if it is
prossible).

the result is whatever you gave the label as the model, if i look at
your code above it is the firstname property of whatever user you gave
to the compound model

Hello Igor,
thank you for the help, but I tried it and it does not work.
I print out getModelObjectAsString() but there was "nothing".
I am confused about what getModelObjectAsString() returns.
Is the result my User that is loaded in my ProfileModel?

Hello,
I want to display diffent values. For this purpose I am
using the Label component with a CompoundPropertyModel.
I want to show user details on a profile page.
But not all user values are set. So I want to display only
values that are not empty strings.
I was thinking about to extend the Label class and override
the isVisible() method. But I do not know how to get the value for
the Label that will be displayed. The Label gets his value with the
wicket id as property expression.
ProfileModel gets an user id and loads a user obj. from DB.
class user extends page {
...
CompoundPropertyModel model = new CompoundPropertyModel(new
ProfileModel(userId));
setModel(model);
Label firstName = new Label("firstName");
add(firstName);
...
}
Thanks
