ck/OnEvent with Context
I am using the example documented here
http://www.chenillekit.org/chenillekit-tapestry/ref/org/chenillekit/tapestry/core/mixins/OnEvent.html
and I can't get the context optional parameter to work.
The relevant code is as follows
*******************
<input t:id="code" t:type="TextField" translate="string" validate="required"
t:mixins="autocomplete, ck/OnEvent"
event="change"
onCompleteCallback="onTextFieldCompleteFunction"
value="auxInvoicedItemUI?.code"
context="${myContext}"/>
*******************
public Object onChangeEvent(List<String> values){}
*******************
public List<String> getMyContext()
{
List<String> list = new ArrayList<String>();
list.add("code101XXX");
list.add(String.valueOf(0));
list.add("codeXXX");
return list;
}
*******************
The problem is that the values parameter of onChangeEvent(List<String>
values)
always returns one value which is the value of
value="auxInvoicedItemUI?.code"
Is there anyway I can have the values parameter also containing the values
returned by getMyContext() method?

Thanks Norman,
You were right. I modified the onInternalEvent() method of
AbstractEventMixin.java and it worked.
I copied both methods below
Thanks again for your help
OLD
*******************
Object onInternalEvent()
{
String input = request.getParameter(PARAM_NAME);
final Holder valueHolder = Holder.create();
ComponentEventCallback callback = new ComponentEventCallback()
{
public boolean handleResult(Object result)
{
valueHolder.put(result);
return true;
}
};
resources.triggerEvent(getEventName(), new Object[]{input}, callback);
return valueHolder.get();
}
*******************
NEW
*******************
Object onInternalEvent(List<String> context)
{
String input = request.getParameter(PARAM_NAME);
final Holder valueHolder = Holder.create();
ComponentEventCallback callback = new ComponentEventCallback()
{
public boolean handleResult(Object result)
{
valueHolder.put(result);
return true;
}
};
Object[] callbackMethodParameters = new Object[context.size() + 1];
callbackMethodParameters[0] = input;
for(int i=1; i< context.size(); i++)
{
callbackMethodParameters[i] = context.get(i-1);
}
resources.triggerEvent(getEventName(), callbackMethodParameters, callback);
return valueHolder.get();
}

Re: ck/OnEvent with Context

I've had a lot of issues with CK and contexts, in my case
InPlaceCheckbox. I basically copied the source and wrote my own. In
this case, the afterRender didn't use the context when creating the
link, this makes the context empty when the onAction fires. And CK's
AjaxCheckbox doesn't use a context at all, apparently. Perhaps the
same thing is happening with the OnEvent?
I've been meaning to submit some bugs on this, but have been so busy.
Another one, if anyone cares, is that the DateTimePicker fails
(JavaScript exception) if it's hidden (in a hidden DIV or
FormFragment.) This failure causes JavaScript processing to stop on
the page causing all sorts of problems.
