#1 Occasion gui problem

[Anonymous]

When the number of IOV parameters is larger than zero the field for adding occasions is unlocked and a non-zero number must be entered.
If one change the number of IOV parameters back to zero the field for adding occasions is again locked (grey) to its CURRENT value. There is no compliant upon saving and the number of occasions can't be changed without again adding an occasion parameter.

Retaining a non-zero number of occasions, even without an occasion parameter, will still considerably slow down the FIM calculation.
