Re: setRenderBodyOnly with ListView and attributes
listviews have nothing to do with tables, they are generic repeaters.
here is the solution
html
body
div class=products
div wicket:id=products class=product
span wicket:id=product class=product/span
/div
/div
/body
/html
the only change needed to code is the tweak to this line:
item.add(new Label(product, product).setRenderBodyOnly(true));

I made a mistake in my first post. The output of wasn't:

div class=product./div
div class=product./div

div class=product./div
/div
but it was:
div class=product./div
div class=product./div
div class=product./div
div class=product./div
So the outer div is missing.
Which is caused by item.setRenderBodyOnly(true). But if I disable (set
to
false) this (the default), I get:
div class=productsdiv class=product./div/div
div class=productsdiv class=product./div/div
div class=productsdiv class=product./div/div
div class=productsdiv class=product./div/div
which is even worse.
A solution (the only?) to this double div problem and at the same time
the
missing attribute problem, is using wicket:container tags. (see
http://apache-wicket.1842946.n4.nabble.com/Panel-in-List-remove-extra-div-td1877053.html
)
This leads to this solution:
div class=products
wicket:container wicket:id=products
div class=product wicket:id=productPanel./div
/wicket:container
/div
Wicket:container tags make it ugly imo, because it violates wickts

Re: setRenderBodyOnly with ListView and attributes
A feature/philosophy is that Wicket HTML is just plain HTML.
This means that a webdesigner can create plain HTML, annotate it with wicket:id
attributes, and then the Java developer can just write Java code.
Plain HTML can be transformed to WicketHTML just by adding wicket:id attributes.
In the case of my problem, which is a very common scenario, you cannot just add
wicket:id's, and let it work. It requires the use of extra divs (or
wicket:container) just to let ListView work. The extra required div causes a
difference between the plain HTML and WicketHTML, and therefore for WicketHTML
the HTML rules differ.
The designer now has to know about these details of Wicket, such as: if the
developer is going to use a ListView, the developer has to wrap extra divs
around some elements.

Re: setRenderBodyOnly with ListView and attributes
actually that is not the philosophy. the philosophy is to make that as
close to reality as possible, and i think wicket comes very damn
close, at least a lot closer then any other.
of course when you are going to start mapping things to wicket
components that have no equivalent in html, like wicket repeaters, you
will have a bit of a mismatch.
on the other hand
divProduct/div
and divspanProduct/span/div
are virtually identical, so there isnt a huge issue adding an extra
span to represent the label
besides, your usecase is almost designed to demonstrate the flaw,
how would you expect to map something like this:
div id=productProduct Name ($Price)/div ?

setRenderBodyOnly with ListView and attributes
hi, I want to have Wicket to generate the following HTML precisely:
div class=products
div class=product./div
div class=product./div
div class=product./div
div class=product./div
/div
But with my code, I don't get further than:
div
div class=product./div
div class=product./div
div class=product./div
div class=product./div
/div
so the class attribute is missing in the outer div.
My Wicket HTML is:
div class=products wicket:id=productsView
div class=product wicket:id=productPanel./div
/div
My code:
ListView productsView = new ListView(productsView, products) {
protected void populateItem(ListItem item) {
item.setRenderBodyOnly(true);
item.add(new ProductPanel(productPanel, item.getModelObject()));
}
};
add(productsView);
What is the Wicket way of achieving this?
(A solution is to use the wicket:container tag, but that's a bit ugly, right?)

Wanted/Required and generated output of solution1 2 ===
html
body
div class=products
div class=productproductA/div
div class=productproductB/div
div class=productproductC/div
/div
/body
/html
==
For this common scenario:
-solution 1 violates Wickets Just HTML philosophy in that the
wicket:container tag is used.
-solution 2 violates Wickets Just HTML philosophy in that an extra unwanted
div is required in WicketHTML (although not visible in the generated HTML).
No other solutions have been found/discussed yet.

send your html and java code, there may be other ways of doing this.

Subject: Re: setRenderBodyOnly with ListView and attributes
I made a mistake in my first post. The output of wasn't:
div
div class=product./div
div class=product./div
div class=product./div
div class=product./div
/div
but it was:
div class=product./div
div class=product./div
div class=product./div
div class=product./div
So the outer div is missing.
Which is caused by item.setRenderBodyOnly(true). But if I disable (set to
false) this (the default), I get:
div class=productsdiv class=product./div/div
div class=productsdiv class=product./div/div
div class=productsdiv class=product./div/div
div class=productsdiv class=product./div/div
which is even worse.
A solution (the only?) to this double div problem and at the same time the
missing attribute problem, is using wicket:container tags. (see
http://apache-wicket.1842946.n4.nabble.com/Panel-in-List-remove-extra-div-td1877053.html
)
This leads to this solution:
div class=products
wicket:container wicket:id=products
div class=product wicket:id=productPanel./div
/wicket:container
/div
Wicket:container tags make it ugly imo, because it violates wickts just
HTML philosophy, even though my problem is a very common scenario.

Add another html div with css class you want around the below list div ;
div class=products wicket:id=productsView
and for the productsViev in the java code setRenderBodyOnly to true.

It somehow feels bad/wrong to move CSS from WicketHTML to JavaCode,
where
it shouldn't belong, for such a common scenario.
It defeats the purpose of having HTML in Wicket. But there probably is
no
other way.
Anyway, thanks for your reply :)
