I extended WebMarkupContainer and called it BodyTag. I would then extend
TextField and mark it as needing focus. I would add my TextField to BodyTag
and have BodyTag look for a component that needed default focus and then add
SimpleAttributeModifier("onload", "document.getElementById('" +
component.getMarkupId() + "').focus();") to BodyTag.Your way looks much cleaner, "java-oriented," especially since I have a lot of other things I add to the "onload" event of the body tag. And the way you have it, it looks like renderHead can get called many times by extending AbstractBehavior. Thanks for the idea, I think I am going to try it your way. I am fairly new to Wicket and am not up to speed on all that it can do and how it does it. I don't know if I answered any of your questions, but you answered a few of mine.
