What's the difference?
Both Panels and Borders have their own markup file, but the markup is used in different ways:
The Border component inserts markup before and after its child components.
{panel} <html> <body> <div wicket:id="myBorder"> <!-- Border markup --> <span wicket:id="myContent">content</span> <!-- Border markup --> </div> </body> </html> {panel}
The Panel component inserts markup into the body of the tag.
{panel} <html> <body> <div wicket:id="myPanel"> <!-- Panel markup --> </div> </body> </html> {panel}
See Panel for more information.
