At constructor time, the panel still isn't 'added' to the page, so the
feedback list cannot be retrieved. In your case, you could alter the
model you provide to the attribute modifier, making the evaluation
'lazy':
if(feedbackul!=null) {
add(new AttributeModifier("class", true, new ReadOnlyModel() {
public Object getObject() {
if(anyMessage()) {
// provide own algorithm here
return "feedbackULINFO";
} else {
return "feedbackULNONE";
}
}}));
}
}
This way, you can even 'not' show the ul in the css:
feedbackULNONE { display : none; }
