Take my second suggestion for the initial problem (
www.joomlaeventmanager.net/forum/develop...lendar?start=6#27208), with the modification you asked for (to add "service: " before custom field 1)
In the
original override file change line 272 and line 277 from
$content .= JemHelper::caltooltip($catname.$eventname.$timehtml.$venue.$eventstate, $eventdate, $row->title . $statusicon, $detaillink, 'editlinktip hasTip', $timetp, $category->color);
to
$content .= JemHelper::caltooltip($catname.$eventname.$timehtml.$venue.$eventstate, $eventdate, $row->title . $statusicon . '<br />service: ' . $row->custom1, $detaillink, 'editlinktip hasTip', $timetp, $category->color);
Then it will "survive" the category selsection.
