GroupsModelArray can not retain data after close groupheader then open
Hi,
You have to listen onChange event to the textbox in the ItemRenderer class and keep the value in the bean
Please check the ZK fiddle sample:
PersonGroupRenderer.java

import org.zkoss.zul.*;public class PersonGroupRenderer implements ListitemRenderer {
public void render(Listitem item, Object data) throws Exception {
if (item instanceof Listgroup) {
Person person = (Person) data;
Listcell listcell = new Listcell();
listcell.setLabel(person.getNation());
item.appendChild(listcell);
} else if (item instanceof Listgroupfoot) {
Listcell listcell = new Listcell();
listcell.setSpan(6);
listcell.setLabel("Total " + data + " Items");
item.appendChild(listcell);
} else {
final Person person = (Person) data;
item.setValue(person);
Listcell cell1 = new Listcell();
Textbox tbx1 = new Textbox();
tbx1.setParent(cell1);
tbx1.setValue(String.valueOf(person.getId()));
cell1.setParent(item);
Listcell cell2 = new Listcell(person.getNation());
Textbox tbx2 = new Textbox(person.getNation());
tbx2.addEventListener(Events.ON_CHANGE, new EventListener(){
public void onEvent(Event event) throws Exception {
InputEvent inpEvent = (InputEvent) event;
person.setNation(inpEvent.getValue());
}
});
tbx2.setParent(cell2);
cell2.setParent(item);
Listcell cell3 = new Listcell(person.getName());
cell3.setParent(item);
Listcell cell4 = new Listcell(String.valueOf(person.getAge()));
cell4.setParent(item);
}
}
}

hai
I have a list box every list item contains one input text box .i set it like
this.listBox_CheckList.setModel(new GroupsModelArray(lsit.tostring(),new LstComparator())
if i enter some data in textbox and i minimised the group header then after i opened the group header data in textbox is not existing it is clearing the text .i want to retain the data even i minimised the Listgroup header .
when ever i opened or closing Listgroup item renderer is calling if i stop that i can retain text box data .reply soon ...
