The Session returns the correct value. Here is the onLoad statement:
WA_setSelectionsInChildList(MM_findObj('Sitzungszimmer'),<?php echo $_SESSION['Sitzungszimmer']; ?>);WA_FilterAndPopulateSubList(rsBestuhlung_WAJA,MM_findObj('Sitzungszimmer'),MM_findObj('Bestuhlung'),0,0,false,': ');WA_FilterAndPopulateSubList(rsDauer_WAJA,MM_findObj('Sitzungszimmer'),MM_findObj('Dauer'),0,0,false,': ');WA_setSelectionsInChildList(MM_findObj('Dauer'),<?php echo $_GET['Dauer']; ?>);WA_setSelectionsInChildList(MM_findObj('Bestuhlung'),<?php echo $_GET['Bestuhlung']; ?>);WA_FilterAndPopulateSubList(rsVeranstaltungVon_WAJA,MM_findObj('Dauer'),MM_findObj('EventVon'),0,0,false,': ');WA_FilterAndPopulateSubList(rsVeranstaltungBis_WAJA,MM_findObj('Dauer'),MM_findObj('EventBis'),0,0,false,': ')
If I use <?php echo $_GET['Sitzungszimmer']; ?> instead of <?php echo $_SESSION['Sitzungszimmer']; ?> it works. This is the "master-value"
that makes all other lists poulate.
Another problem is, if one of the other GET parameter is emtpy or missing, none of the lists is being populated.
