document template: parameter alpha must not be null

Since 5.14: When generating a document template i get an error saying: parameter alpha must not be null. It does not happen in de test environment or local. It only happens in production environment. Exactly the same data. Someone has a clue?

Bas thanks. I eliminated soms dynamic image controls from the template document and now it works. I noticed that it does not have to do with the picture, but with the place of the control in the template. Issued a ticket, however the return question will be to exactly reproduce it in a small test environment. I think this will not be possible so it is useless to spend the time for that. Offer: I will travel to Rotterdam and exactly show it. This will turn out to be quicker :-)
