The input method is obsolete - running codeunit in NAV 2013 R2

Hello,

Is there any changes in dialog.input in NAV2013 R2? I encounter the error "The input method is obsolete."

I think dialog.input is not working anymore. My sample code below:

OnRun
vDialog.OPEN('Enter Date #1########### (mm/dd/yyyy)',vDate);
vDialog.INPUT(1,vDate);
vDialog.CLOSE;

vDialog = dialog

vDate = Date
