Every time I try to refresh the data having created "My First Wave App" as the module instructs, I am getting a "failed" status and the error is
"Error executing node Event_IsClosed_Flag: invalid field expression case when daysBetween(toDate(ActivityDate, "yyyy-MM-dd"), now()) >= 0 then "true" else "false" end for field 'IsClosed': Unknown IDTOKEN: ActivityDate (02K58000000H1dzEAC_03C580000005Iv4EAE)"

Has anyone else experienced this in this unit?

Thanks
