Hi Geoff,
You can pass an instance of the RenderCommand that could capture the
context, hopefully this snippet can give a hint.
Regards,
Dmitry
for (int i = 0; i < emailIds.length; i++)
{
String emailId = emailIds[i];
boolean display = displayStatusArray[i];
// Set tempId for getEmailStatusZoneId()
tempId = emailId;
// There may be multiple instances of this component being
refreshed at the same time,
// so we need to render it immediately
ajaxResponseRenderer.addRender(getEmailStatusZoneId(),
(RenderCommand) (writer, queue) -> {
// Initialise before rendering
EmailDeliveryStatus.this.tempId = emailId;
EmailDeliveryStatus.this.show = display;
setupEmail();
((RenderCommand) emailStatusZone.getBody()).render(writer, queue);
initJavaScript();
});
}
