Symptoms
I created a SmartObject based on the SharePoint content service instance. It has all the standard methods and they are all working except the get list function when I use a date as an input value (in SMO tester and running process) in the respective fields. The SharePoint source is basically a standard events list with a few separate columns. The date fields are standard default SharePoint columns. The get list function runs fine if I don't use any date fields as input.
Diagnoses
I recreated it on my side and all calendar function works. As soon as you apply a filter the SMo tester tool returns 0 results.
Resolution
A Cold fix was applied for this issue and is now resolved.
