developer vs server/client

I have a perfect :D solution running on my developer.

This evening I installed it on a (mac) server to do a demo. I created a new (related) row, and another and… Bingo my first error message… Tried to do the same in my developer and again on the client. Without an error…

I also manipulate a date to show a month (by text) and week (by number). On my developer version this is no issue at all…

On my client this gives an null value for the month and a 0 value for the week. Such every time, over and over but now if I am working with my developer.

How can I find the issue an how can it be that a perfectly good behaving solution from within my developer suddenly shows errors when I run it as a client from a server…

Additionally: it looks like at least the date part comes from utils.dateFormat. I call that twice.

Once to set that month name and once to set that week number. When I run developer and run the solution from within developer there is no issue. When I run from a client these two values are as mentioned in the previous post null and 0…

What is the error text?

for the first I don’t remember. Will try to emulate it later today…

for the second: none…
