I am following the free guide... I got to render some results, which are
very strange however:
I created a Panel descendant "Icon". I want many instances of it in a
repeater.
Home.html (excerpt):
<div wicket:id="uiIconList"></div>
Home.java (excerpt):
RepeatingView lst = new RepeatingView("uiIconList");
lst.add(new Icon(lst.newChildId()));
lst.add(new Icon(lst.newChildId()));
lst.add(new Icon(lst.newChildId()));
Icon.java (not imports etc):
public class Icon extends Panel {
public Icon(String id) {
super(id);
}
}
Icon.html:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<wicket:panel>
<div class="hasmenu icon iconauthor" title="AUTOR: PEREIRA,
Márcio" style="left:63%; top:23%"></div>
</wicket:panel>
</body>
</html>
RESULT!
<div wicket:id="uiIconList">
<wicket:panel>
<div class="hasmenu icon iconauthor ui-draggable" title="AUTOR:
PEREIRA, Márcio" style="left:63%; top:23%"></div>
</wicket:panel>
</div>
<div wicket:id="uiIconList">
<wicket:panel>
<div class="hasmenu icon iconauthor ui-draggable" title="AUTOR:
PEREIRA, Márcio" style="left:63%; top:23%"></div>
</wicket:panel>
</div>
<div wicket:id="uiIconList">
<wicket:panel>
<div class="hasmenu icon iconauthor ui-draggable" title="AUTOR:
PEREIRA, Márcio" style="left:63%; top:23%"></div>
</wicket:panel>
</div>
My questions:
1. Shouldn't the uiIconList <div> be substituted/ommited?
2. Shouldn't <wicket:panel> be substituted/ommited?
3. Is there an equivalent to newChildId() on ListView?
4. newChildId() generates a wicket:id for each new Icon. Why is it not
rendered?
5. Why don't I get an errror considering the Ids produced by newChildId()
exist in java code/container and not in HTML???
Wow :D Hope I could be clear enough, Tx for your help!
