I am rather new to wicket, coming from a Tapestry angle. Anyway, my
question is rather basic.
I gather that all components on a page must be rendered?
Suppose I have a common dataview with a dataprovider on a page, basic
CRUD-stuff. My page constructor looks like this:
try {
...query the database and build the provider and dataview
} catch (SQLException e) {
feedback.error("Very bad things happened");
// What to do here??
}
What is the best practice for removing/disabling components in the
catch clause? I can not create the dataview (called "dataview" in the
HTML) since the backend has died but wicket needs a component there?
Currently I do somehting like this
} catch (Exception e) {
add(new Label("dataview", "").setVisible(false));
}
and that works fine but it seems a bit un-DRY to have to add dummy
components for the error case. Is my understanding correct?
Cheers,
/Johan
