I'am very impressed about the progress in RichFaces 4 and I' am using the new version all ready in a new project. I used different panel types and realized that their headers have by default diffrent layouts and heights, so I tested the 4 different panels with headers :
I think for a consistent look and feel, the headers of these panels should have the same height and layout.
please rise an issue on that.
for your application you could overcome that by using predefined rf-* classes.
