Re: Wicket and CoC

[Ricardo Mayerhofer <ri...@gmail.com>]

Very nice indeed. Based on your example I build my own:

public class ConventionalComponentResolver implements IComponentResolver {

	public boolean resolve(MarkupContainer markupContainer, MarkupStream
markupStream, ComponentTag componentTag) {		
        CharSequence wicketId = componentTag.getString("wicket:id");
        if ( "submitLink".equals(wicketId) ) {
        	markupContainer.autoAdd(new SubmitLink( "submitLink" ),
markupStream);
            return true;
        }
....
