Re: wicket panels and parent class

I guess I am used to the jsp:include method of including panel type objects since I am originally a JSP developer and then anything in the panel instantly has access to the variables defined in the surrounding parent. I guess I could pass along a HashMap of data to the Panel when its

Re: wicket panels and parent class

It may not be a best practice, but if MyInfoPanel does not need to be reusable you can make it an inner class of MyProfile. Then userId can be accessed directly. Phil On Mon, Sep 29, 2008 at 6:45 AM, Steve Swinsburg [EMAIL PROTECTED] wrote: Hi all, I'm a new Wicket user and am developing an
