I think I've figured it out: 1) the requestAction call in the page element is not neccessary - the data is already available from the first pass through the controller 2) the reason my code was not completing was that the iCalcreator's returnCalendar() method ends in die() (why would this be a good thing?)
Once I: removed the requestAction call in the element file; rewrote the calendar rendering helper to use iCalcreator::createCalendar which doesn't die at the end; and set the layout in my controller ($this- >layout = "ical";); then all seems well.
