Couldn't you use a VelocityPanel to generate your markup and have it
parse the markup after it's generated to avoid the whole "need to use
the right markup ids" part? I was thinking about doing something like
this for generating dynamic editor forms (a la Trails) for objects,
since Wicket doesn't like you putting TextFields on <spans> (you must
use an <input> tag). I was going to have a Velocity script that
decides what type of tag to spit out based on the type of component in
the list.
What I found simple, which I perhaps did not explain clearly.. Where to only
accept basePanels in forexample addMenu method, that way a base panel would
look something like this:
public class BasePanelItem extends Panel {
public final static String ITEM_ID = "item";
public AccordionPanelItem() {
super(ITEM_ID);
}
Now we have the id fixed...
Then the user only need add what ever user wants when user extends
basePanelItem.. So this solves that too... And the problem with
attaching to wrong tags are solved too... There might be some overhead
because each time you want todo something special you need to create a
panel, but I think it's worth it..
What did you think of this approach?
PS, youve seen the web beans project right?
http://wicketwebbeans.sourceforge.net/
Yes, I've seen WWB. But, I'm a "roll your own" kind of guy.
Actually, I'm going through this experiment to help me learn Wicket.
I was part of the Trails team and I was wondering how we'd do the same
thing in Wicket.
