As far as i understood you can't do this with common tapestry select
component. It has no context for VALUE_CHANGED event except selected value.
But you can try to implement your own logic.
Just copy logic responsible for VALUE_CHANGED event from tapestry select
component to mixin and add context to generated link:
public class MyMixin {
@InjectContainer
private Select component;
@Parameter
private String zone;
@Parameter
private Object[] context;
@AfterRender
void linkZone() {
Link link = resources.createEventLink(changed, context);
JSONObject spec = new JSONObject(selectId,
component.getClientId(), zoneId, zone, url, link.toURI());
javascriptSupport.addInitializerCall(linkSelectToZone, spec);
}
//... changed event handler that will trigger VALUE_CHANGED event with
context
}

I have a ajaxformloop. The list of objects that I want to display has two
fields. Both of them are enums and I want to be able to refresh the second
enum when I make my selection on the first. For example
Field 1 Filed 2
name is
startDate before
My code looks like
t:form
div t:type=ajaxformloop t:id=filters t:source=filterSections
t:value=currentFilterSection t:encoder=encoderFilterSection
t:zone t:id=zoneComparator t:update=show
select t:id=selectProperty t:type=select
zone=zoneComparator t:model=propertyModel
t:value=currentFilterSection.value.properity
/select
select t:type=select t:model=comparatorModel
t:value=currentFilterSection.value.comparator
/select
/t:zone
/div
/t:form
Now I have done this before when but not in the ajaxformloop.
The problem that I have here is that I have a list of object and I am not
sure how I can signal what row is being changed.
I have looked at the documentation of the select but I cant find any way to
send information about the row in question. If I could send that then I
could modify the list.
Any suggestions how this can be achieved?
cheers
