Why can't I use multiple selection with listbox in zk framework? - zk

Question

I followed zk demo to create listbox with multiple selection.
Here is my zul file:
<window title="demo"
xmlns:h="http://www.w3.org/1999/xhtml"
xmlns="http://www.zkoss.org/2005/zul"
apply="com.viettel.voffice.controller.ListboxController">
<listbox id="lb" model="${$composer.list}" multiple="true" checkmark="true" mold="paging" pageSize="10">
<listhead>
<listheader label="STT"/>
<listheader label="Name"/>
</listhead>
<template name="model">
<listitem>
<listcell label="${forEachStatus.index}"/>
<listcell label="${each}"/>
</listitem>
</template>
</listbox>
Controller:
public class ListboxController extends SelectorComposer<Component> {
#Wire
private Listbox lb;
private ListModelList list;
#Override
public void doAfterCompose(Component comp) throws Exception {
super.doAfterCompose(comp);
List listData = new BigList(1000);
list = new ListModelList(listData);
lb.setModel(list);
lb.renderAll();
lb.setMultiple(true);
}
#Override
public ComponentInfo doBeforeCompose(Page page, Component parent, ComponentInfo compInfo) {
return super.doBeforeCompose(page, parent, compInfo);
}
public ListModelList getList() {
return list;
}
BigList.java:
public class BigList extends AbstractList<Integer> {
private int size;
public BigList(int sz) {
if (sz < 0) {
throw new IllegalArgumentException("Negative not allowed: " + sz);
}
size = sz;
}
public int size() {
return size;
}
public Integer get(int j) {
return Integer.valueOf(j);
}
}
And here is what zk display:

Why doesn't listbox display multiple selection?
I have just solved it. Just add this line:
model.setMultiple(true);
:D

Answer 1

You made little mistake you have to add this in afterCompose() method
list.setMultiple(true);
