Hi Mark,
Nothing special in my code. I was just following sample of AjaxFormLoop on
Tapestry Jumpstart (
http://jumpstart.doublenegative.com.au/jumpstart/examples/tables/ajaxformloop1)
and combined it with your suggestion on thread: "Update Zone inside
AjaxFormLoop".
Here is the snippet from my source:
------------------
* I have master-detail form in my .tml file:
<!-- this is the master (there is one T5.2 Select Component) -->
<t:label for="locationId"/>
<t:select t:id="locationId" t:value="record.locationId"
t:model="locationModel" t:zone="machineZone"/>
<!-- details is using AjaxFormLoop (there is one Select component where the
options is based on master's Select component) -->
<fieldset t:type="AjaxFormLoop" t:id="detail" t:source="detailHolderList"
t:value="detailHolder" t:encoder="encoder">
<t:unless t:test="detailHolder.deletedRecord">
<t:submitnotifier>
<legend>Machine</legend>
<t:label for="machineId"/>
<t:zone t:id="machineZone" id="${machineZoneId}">
<t:select t:id="machineId"
t:value="detailHolder.machine.machineId" t:model="machineModel"
t:validate="required"/>
</t:zone>
<t:removerowlink>remove</t:removerowlink>
</t:submitnotifier>
</t:unless>
<p:addRow>
<t:addrowlink>Add Machine</t:addrowlink>
</p:addRow>
</fieldset>
--------------------------
* on Java file:
On this snippet, I use @Persist to persist into session, but of course we
can use session.setAttribute() and session.getAttribute() if we want to have
more control about session keys and stored information.
@InjectComponent
private Zone machineZone;
// this detailHolderList contains key of records on AjaxFormLoop. We use
these keys in MultiZoneUpdate.
@Persist
private List<DetailHolder> detailHolderList;
@Persist
private SelectModel machineModel;
public String getMachineZoneId() {
return "detailHolder-" + detailHolder.getKey();
}
CsActivityHolder onAddRowFromDetail() {
Machine newMachine = new Machine();
DetailHolder newDetailHolder = new DetailHolder(newMachine, true, 0 -
System.nanoTime());
detailHolderList.add(newDetailHolder);
return newDetailHolder;
}
void onRemoveRowFromDetail(DetailHolder detailHolder) {
int index = detailHolderList.indexOf(detailHolder);
DetailHolder holder = detailHolderList.get(index);
if (holder.isNewRecord()) {
holderList.remove(detailHolder);
} else {
holder.setDeletedRecord(true);
}
}
@OnEvent(value = EventConstants.VALUE_CHANGED, component = "locationId")
public Object onValueChanged(Long locationId)
{
machineModel =
machineManager.getMachineSelectModelByLocationId(locationId);
MultiZoneUpdate result = null;
for (CsActivityHolder holder : csActivityHolderList) {
String idOfDetailSelect = "machineZone-" + holder.getKey();
if (result == null) {
result = new MultiZoneUpdate(idOfDetailSelect, machineZone);
} else {
result = result.add(idOfDetailSelect, machineZone);
}
}
return result;
}
Using above code, when user change master's Select component, then all
detail's Select component (inside ajaxformloop) is being updated.
