Alternative flows can be handled using panels or fragments possibly
combined with component replacements.
As for the error-flow, and I don't really see why:
try {
...query the database and build the provider and dataview
} catch (SQLException e) {
feedback.error("Very bad things happened");
// What to do here??
}
should generate a different component structure rather than an error page.
