OTRS develop

[tina]

Hi,

I'm tying to develop a link in web form "AgentITSMWOrkorderAgent.dtl" that allows to redirect user to another web form,

and in the file "AgentITSMWOrkorderAgent.pm" I write this code:

if ( $Self->{Subaction} eq 'Close' ) {
return $Self->{LayoutObject}->PopupClose(
URL => "Action=AgentITSMWorkOrderEdit;WorkOrderID=$WorkOrder->{WorkOrderID}",
);
}

but I always have this error No WorkOrderID is given!

Can any one help me,

Thank you,
