I see that thread is closed, but the problem still exist. What I meant was that the correct Java version was used by Omniscope. However, we are still experiencing the following problem:
Only for the first week in 2013, converting numeric value '201301' to a datevalue (format yyyyww) results in null... for all other weeks it works.
I understand what goes wrong now based on what Steve is explaining. Problem is that I dont want to use 2.8 yet. I will try to use a workaround for the first week of the year.
