Thank you Tobias,
I followed your advice and it worked, after looking at
https://ci.apache.org/projects/wicket/guide/6.x/guide/componentLifecycle.html
it seems the best way to fix this is e.g.:
@Override
protected void onConfigure() {
if(loginForm.hasError()) {
setVisible(true);
} else {
setVisible(false);
}
}
The lifecycle is a bit off from my wicket 1.3/ 1.4 memories it seems :)
Best,
Korbinian
