Dynamically change feedback panel border color?

2010-03-04 Thread David Chang 

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:

div wicket:id=feedbackHolder /

Java code:

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

I *think* you want to handle that inside of onRender:

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.
