Hi Abdul & Ingo,
thank you for your reply.
You are both right, I won't delete the messages from the container.
Currently I allocate the field within the feeder class with mo_entity->set_property method. So I will not get an error message.
@Abdul: I used BRF+ before, but I dont like this Framework, there makes some problems like transport and the usability is for me not the best. The cause might also be that I haven't enough experience knowledge.
@Ingo: Very useful tips, thanks!
Best regards,
Hasan
