Also you can pass as second argument in AttributeModifier IModel object
which return "error" on if there feedback message available.
Similar to this:
new AttributeModifier("class", new Model() {
@Override
public Serializable getObject() {
if (currentBill != null && currentBill.id ==
item.getModelObject().id) {
return "success";
}
return null;
}
})

Thanks a lot.

And remember that you must not use isValid() in onComponentTag() to change tag attributes. You must store the validness in a transient property in onConfigure() or onBeforeRender() and check that that property in onComponentTag(). In fact, at least one component in 6.5.x (which we use currently in our production system) got this wrong as well. Some day, I'll write a post asking why that change was done between 1.4 and 6.x.

Re: user interface design: if any error, textbox channge to red ... ...
Hi! Feedback messages are cleanup up (removed) after each request. The attribute modified you added to the component, remains in place if the page is stateful. That's why the field still has the "error" class after a reload. You can do a number of things to make this work, but the essence is that the attribute should only be updated if the form component has errors. You can then add this behavior (e.g. the attribute modifier) to all formcomponents when constructing the form. This can also be automated with a component instantiation listener. To only update the attribute if the component has errors, override method isEnabled on the behavior, cast the component to a FormComponent and return !formComponent.isValid().

However, if I press "F5", the feedback message disappears, the textbox remains red. It seems that "error" stays there forever. Did I missing something?
