Hi,

When I try to use a Date object (javascript) in a script task I get the following exception:

This is the javascript code I use (I'm going to set the date according to a process variable later, but first I must be able to create a Date object..):

//set timeDate
var tD = new Date();

Why?

Thanks,
caiw
