Custom date format 29 februari

Hi,

I implemented a dataView with a date field on it and a button to move to the next day.

The format of the date field is a 'Custom date format' reading: EEEE d MMMM. On normal day's it's showing the date like: Wednesday 20 January

However, when I am at februari 29th and I move to the next day (which is 1th of march), I get an error:'INVALID DATE'

After removing the custom date format, moving to the next day proves no problems.

Anyone having the same error and a solution?

Kind regards,

Rolf
