I may be missing something but what about just setting the visible
property?
for( section : sections ) {
Label label = new Label( ...
label.setVisible( section.id != 0 );
add( label )
}

Hi all,
I am looking into implementing some presentation logic and wonder what
the best approach is.
In my usecase I have a form and after the user submitted it I present
the values back in a page. There is an optional option that I want to
display if the user had given feedback to the option.
ATM I have implemented the "display back" page in a panel:
<html xmlns:wicket="http://wicket.apache.org/";>
<wicket:panel>
...
<div wicket:id="subSection">subSection</div>
...
And in my java class I do:
...
StringResourceModel ssectionResult = new StringResourceModel(
"subSection.add", this, new Model(model));
add(new Label("subSection", ssectionResult));
And in my properties files I have:
subSection.add=Subseccion: $\{subSection\}
However that leads to the problem that
if (subSection ==null)
it will be displayed as "Subseccion: ${subSection}"
else
it will be displayed as "Subseccion: 2.1. NOMBRAMIENTOS,
SITUACIONES E
INCIDENCIAS"
What I am now looking for is a kind of if test for <div
wicket:id="subSection">subSection</div>.
something like
<wicket:if test="subSection!=0">
<div wicket:id="subSection">subSection</div>
</wicket:if test="subSection!=0">
How can I implement this test with wicket?
