That will work, but I already knew that.
The whole problem is that it violates Wickets "just/pure HTML" philosphy in
that an extra unwanted div (or span) is required in WickedHTML just to make
ListView work, even though it's a common scenario.
If ListView would follow Wickets philosophy, it would support this WicketHTML:
<div wicket:id="products" class="products">
<div wicket:id="product" class="product">Product1....</div>
</div>
At the moment, there are two known workarounds in this discussion:
1) Accept the violation of "just HTML" by using the extra DIV.
2) Accept the violation of "just HTML" by using wicket:container.
