smartgwt calendar day lane view error

[sidharth1917]

I have included daylane view for calendar by showDayLanes = true and dayView = true, setCurrentViewName = ViewName.DAY. When events are rendered i get the following error, e.g. say there is an event for 7 may. when i select 7 may from calendar it shows error

Any reason ? Also there is no day lane show case example in smartgwt but smartclient do provide example for day lane. Can i get example for reference

If you can show your Calendar configuration, including DataSource if there is one, then we can take a look.
