Re: Dynamically change feedback panel border color?
For FeedbackPanel, I am not sure how to do this. I tried onComponentTag(), etc.
and it seems there is always compile error. Looks like FeedbackPanel is a
special beast.

Re: Dynamically change feedback panel border color?
I *think* you want to handle that inside of onRender:
http://wicket.apache.org/docs/1.4/org/apache/wicket/Component.html#onRender(org.apache.wicket.markup.MarkupStream)

Dynamically change feedback panel border color?
I am using a div with border color to enclose feedback messages. I can control
whether to generate the feedback div based on whether there is any message to
render. Now I hope to change its border color depending on the severity of the
message. But (1) always causes error:
Cannot modify component hierarchy after render phase has started (page version
cant change then anymore).
How can I change the border color when there is message to render? What is the
best way?
Thanks!

HTML:
Java code:
add(new FeedbackPanel("feedbackHolder") {
@Override
public boolean isVisible() {
(1) if (anyErrorMessage())
add(new SimpleAttributeModifier("class", "redBox"));
return anyMessage();
}
});
