That would be great. :-)

The ###FIELD_WRAPPER subparts are used for hiding the subpart content if
the subpart either is hidden by configuration (e.g. hideFields,
hideColumns) or is empty (e.g. an event has no speakers assigned, so the
"speakers" subpart needs to be hidden in the single view).

Have a look at tx_seminars_pi1::setSpeakersMarker to get the knack:

/**
 * Fills in the matching markers for the speakers or hides the subpart if
 * there are no speakers.
 */
private function setSpeakersMarker() {
	if (!$this->seminar->hasSpeakers()) {
		$this->hideSubparts('speakers', 'field_wrapper');
		return;
	}

	$this->setSpeakersMarkerWithoutCheck('speakers');
}


This function is called from tx_seminars_pi1::createSingleView():

///////////////////////////
// Single view functions.
///////////////////////////

/**
 * Displays detailed data for a seminar.
 * Fields listed in $this->subpartsToHide are hidden (ie. not displayed).
 *
 * @return string HTML for the plugin
 */
private function createSingleView() {
	[snip]
	$this->setGenderSpecificHeading('speakers');
	$this->setSpeakersMarker();
	$this->setGenderSpecificHeading('partners');
	$this->setPartnersMarker();
	$this->setGenderSpecificHeading('tutors');
	$this->setTutorsMarker();
	$this->setGenderSpecificHeading('leaders');
	$this->setLeadersMarker();

Hope this helps,


Oliver
