Customized FeedbackPanel question
We have a requirement to render the offending FormComponent with a visual change (not an indicator...but a style change such as background is red) and show the error message below the component.
I have created a customized FeedbackPanel for this so this is not a problem.
The problem we have is that we also have a FeedbackPanel at the top of the page which renders the error message as well. We don't the message to be rendered twice.
I have attempted this behavior by playing around with the IFeedbackMessageFilter, onBeforeRenderer and markRendered method but my efforts have failed. I was hoping that there was a onBeforeXXX method that can be called so I can determine if what messages are to be renderered in the FeedbackPanel before they are actually renderered. It appears that the component is rendered right after onBeforeRender before moving on to the next child component.
Has anyone else come into this requirement and have found an acceptable solution? Is there another onBeforeXXX method that is called before rendering and traverses the entire component graph that I may override and mark messages as rendrered?
Thanks in advance.

you are welcome to build whatever strategy you want.
for example you can create two classes: local and global feedback
panel, and in the global one when you filter a message you are visit
all local panels and see if theyve accepted or would accept that
message using their filter.

I have the same problem. If you build a heavy componentized page with
lots of panels your solution is hard to implement.
Lets say there are on the page:
- some panels has it's own FeedbackPanel (properly filtered)
- some panels with no FeedbackPanel
Is there a possibility to put a "global" FeedbackPanel on the page and
put in it ONLY the messages that have been filtered out by every "local"
FeedbackPanel?
Or the other way around: global FeedbackPanel filters out anything that
local FeedbackPanels accept.

why dont you simply check in your filter if the reporter component is
a descendant of the form and then ignore the message?
