No solution for the parameter problem, but a workaround!
1. In development everything works fine and looks like (picture 1).
2. In production at Strato AG with a Linux system, it looks like this after the workaround
3. Old master/detail applications work normally and look like this (picture 3).
The workaround is because absolute no global parameter got posted to the detail application.
Nothing of these parameters will arrive to the detail application (picture 4 and 5).
So the behavior is different to other older applications in production at Strato AG with a Linux system.
The workaround with an additional strange thing:
I have set the relevant parameters extra with an Ajax Event (see picture 6).
An additional strange thing in Ajax Event was, that I could select available hidden fields in the record but were not really effective and had von value. So the parameter in Ajax Event containing only values if you make the field displayed (picture 6 and 7). UID is the displayed field of “unternehmens_id”.
In the detail application I had to simulate the normal going back to the overview application
(Read always the meaningful file name text of the pictures!)
That other old applications work fine in production at Strato AG with the Linux system that shows you that it is logically not only a problem of the environment in production (older master/detail applications then would not work as well – but they still work).
This is a problem of the new generator as well. See again an old application in contrast to the new workaround (picture 3 and 4).
Please find attached 8 pictures and the diagnostic file from production as PDF.
The real solution has to come from ScriptCase developer!
