Now i got it finally!! It sometimes (very often) – is very hard to understand the GDL-handbook – because it is so poor in examples. The textal description is right – but very 🙄 😯 😈 🙁 without an minimal amount of examples)
You have to repeat the valuename once again instead of displayParam! – thats all!
Why dont they tell this clear!
Wy not writing simply: repeat parameter name instead of displayParam – so that onyone can simply understand it?
It is written there in a way – my simple mind could not understand it for hours! I had to find out with trial and error – seeking!
