I have a listbox in a zul page with a mold="paging"
<window id="browseWin" title="Eventos"
width="720px" border="normal"
use="com.inabox.taller.controller.EventoListWindow">
<listbox id="lbEvento" multiple="true" rows="10" mold="paging">
<listhead>
<listheader label="Evento" />
<listheader label="Prioridad" width="80px"/>
<listheader label="Fecha" width="90px"/>
</listhead>
</listbox>
</window>
Then in my java code:
public void onCreate() {
Listbox lbEvento = (Listbox) this.getFellow("lbEvento");
EventoDAO dao = new EventoDAO();
List<EventoBean> eventoList = dao.findAll();
lbEvento.getItems().clear();
for (EventoBean eb : eventoList) {
Listitem li = new Listitem();
li.setValue(eb);
li.appendChild(new Listcell(eb.getNombre()));
li.appendChild(new Listcell(String.valueOf(eb.getPrioridad())));
li.appendChild(new Listcell(eb.getFechaInicioAsString()));
lbEvento.appendChild(li);
li.addEventListener(Events.ON_DOUBLE_CLICK, new EventListener() {
public void onEvent(Event event) throws Exception {
onEdit(event);
}
});
}
}
}
When I add/delete/udate an item i reload the whole listbox with all the data in my table but i go this messagebox
"The paging component cannot be removed manually. It is removed automatically when changing the mold"
I know it could be a better approach use databinding or a model but I just doing an example for my junior programmers..
Any help?
TIA
It looks like a bug in 3.5.1, could you upgrade to 3.5.2?
I upgraded to 3.5.2 and got the same problem...
I can not reduplicate it in 3.5.2 with my sample code,
could you provide simple one that can duplicate the error ?
by the way, make sure you clear the item with 'lbEvento.getItems().clear();' not 'lbEvento.getChildren().clear();'
my example here, works in 3.5.2 , fail in 3.5.1
<window id="browseWin" title="Eventos" width="720px" border="normal">
<button label="click" >
<attribute name="onClick"><![CDATA[
lbEvento.getItems().clear();
for(int i=0;i<40;i++){
Listitem li = new Listitem();
li.setLabel("AAA"+i);
li.setParent(lbEvento);
}
]]></attribute>
</button>
<listbox id="lbEvento" multiple="true" rows="5" mold="paging" pageSize="5">
<listhead>
<listheader label="Evento" />
</listhead>
<listitem label="A"/><listitem label="A"/><listitem label="A"/><listitem label="A"/>
<listitem label="A"/><listitem label="A"/><listitem label="A"/><listitem label="A"/><listitem label="A"/>
<listitem label="A"/><listitem label="A"/><listitem label="A"/><listitem label="A"/><listitem label="A"/>
</listbox>
</window>
Thanks Dennis.
I double-check my Zk jars to be sure they are 3.52 and they are.
You code works oK too but my problem persist, so I debug my code and I find put the problem is in the line
lbEvento.getItems().clear();
Then in my java code I did:
lbEvento.setMold("");
lbEvento.getItems().clear();
for (EventoBean eb : eventoList) {
Listitem li = new Listitem();
li.setValue(eb);
li.appendChild(new Listcell(eb.getNombre()));
li.appendChild(new Listcell(String.valueOf(eb.getPrioridad())));
li.appendChild(new Listcell(eb.getFechaInicioAsString()));
lbEvento.appendChild(li);
li.addEventListener(Events.ON_DOUBLE_CLICK, new EventListener() {
public void onEvent(Event event) throws Exception {
onEdit(event);
}
});
}
lbEvento.setMold("paging");
And now it is working OK... :-)
very strange, in past of my experience , I did the stupid listbox.getChildren().clear(); in paging mold.
:(
