JAVA : ZK framework how to set two bean to listbox? - listbox

Question

I am trying to make editable listbox that gives user ability to update listitem or cancel it.But I can't get selected item for save it on another bean and then if user clicks cancel , show original record. This returns me null.
Listitem listitem = self.getParent().getParent();
Listbox listbox = listitem.getListbox();
alert(listbox.getSelectedItem().getValue());
Also I am using zscript on .zul file for making this operation. here my listbox and update function
<listbox id="listModel" rows="10" mold="paging" pageSize="10"
selectedItem="#{mainCtrl.selected}" fixedLayout="true"
model="#{mainCtrl.model}">
<listhead>
<listheader
label="${c:l('SYSADM.ManageImportedSubscribers.table.MSISDN')}"
sort="auto" />
<listheader
label="${c:l('SYSADM.ManageImportedSubscribers.table.Date')}"
sort="auto" />
<listheader
label="${c:l('SYSADM.ManageImportedSubscribers.table.CO_ID')}"
sort="auto" />
<listheader
label="${c:l('SYSADM.ManageImportedSubscribers.table.Customer_ID')}"
sort="auto" />
<listheader label="Update ?" sort="auto" />
</listhead>
<listitem self="#{each=MANAGE_IMPORTED_SET_DATA}">
<listcell>
<label value="#{MANAGE_IMPORTED_SET_DATA.MSISDN}"></label>
<textbox value="#{MANAGE_IMPORTED_SET_DATA.MSISDN}"
visible="false" />
</listcell>
<listcell>
<label value="#{MANAGE_IMPORTED_SET_DATA.IMPORT_ID}"></label>
<textbox value="#{MANAGE_IMPORTED_SET_DATA.IMPORT_ID}"
visible="false" />
</listcell>
<listcell>
<label value="#{MANAGE_IMPORTED_SET_DATA.CO_ID}"></label>
<textbox value="#{MANAGE_IMPORTED_SET_DATA.CO_ID}"
visible="false" />
</listcell>
<listcell>
<label value="#{MANAGE_IMPORTED_SET_DATA.CUSTOMER_ID}"></label>
<textbox value="#{MANAGE_IMPORTED_SET_DATA.CUSTOMER_ID}"
visible="false" />
</listcell>
<listcell>
<button label="Update">
<attribute name="onClick">
Button update;
Button delete;
Button save;
Button cancel;
update = self;
delete = self.getNextSibling();
update.setVisible(false);
delete.setVisible(false);
Listitem listitem = self.getParent().getParent();
int i = 0 ;
while(i != 4){
Listcell listcell = (Listcell)listitem.getChildren().get(i);
((Label)listcell.getChildren().get(0)).setVisible(false);
((Textbox)listcell.getChildren().get(1)).setVisible(true);
i++;
}
self.getParent().appendChild(save=new Button("Save"));
save.addEventListener("onClick",new EventListener() {
public void onEvent(Event arg0) {
alert("SAVE CLICKCED");
}
});
self.getParent().appendChild(cancel = new Button("Cancel"));
cancel.addEventListener("onClick",new EventListener() {
public void onEvent(Event arg0) {
Listitem listitem1 = self.getParent().getParent();
int i = 0 ;
while(i != 4) {
Listcell listcell = (Listcell)listitem1.getChildren().get(i);
((Label)listcell.getChildren().get(0)).setVisible(true);
((Textbox)listcell.getChildren().get(1)).setVisible(false);
i++;
}
Listcell listcell = (Listcell)listitem1.getChildren().get(4);
((Button)listcell.getChildren().get(0)).setVisible(true);
((Button)listcell.getChildren().get(1)).setVisible(true);
((Button)listcell.getChildren().get(2)).detach();
((Button)listcell.getChildren().get(2)).detach();
}
});
</attribute>
</button>
<button label="Delete" onClick="onDelete()"></button>
</listcell>
<listcell></listcell>
</listitem>
</listbox>

The data binding support save-when and load-when concept in annotation. You can specify "save-when: none" in zul annotation so the databinder will not save data from UI into bean for you automatically. However, then you have to do the "save" by yourselves in your event listener.
<listcell><label value="#{MANAGE_IMPORTED_SET_DATA.MSISDN}" ></label><textbox value="#{MANAGE_IMPORTED_SET_DATA.MSISDN, save-when='none'}" visible="false" /></listcell>
<listcell><label value="#{MANAGE_IMPORTED_SET_DATA.IMPORT_ID}"></label><textbox value="#{MANAGE_IMPORTED_SET_DATA.IMPORT_ID, save-when='none'}" visible="false" /></listcell>
<listcell><label value="#{MANAGE_IMPORTED_SET_DATA.CO_ID}" ></label><textbox value="#{MANAGE_IMPORTED_SET_DATA.CO_ID, save-when='none'}" visible="false"/></listcell>
<listcell><label value="#{MANAGE_IMPORTED_SET_DATA.CUSTOMER_ID}"></label><textbox value="#{MANAGE_IMPORTED_SET_DATA.CUSTOMER_ID, save-when='none'}" visible="false" /> </listcell>
For details, you can check this JavaDoc (search "save-when"):
