Anton what is CF9 version, 9.0.2 or 9.0.1 / 9.0.0 with APSB12-15 or above?
If above match then could be postParametersLimit.
Edit neo-runtime.xml change setting from 100 to say 500 (do your own testing to know what number) and restart CF application service to apply.
Thank you for your replay. CF version is 9.0.2. Sorry, I am not sure what APSB12-15 means. But anyway, I have changed
"postParametersLimit" variable to the bigger figure and it works now. I thought, post limit is only in CF10, but I should try to check on this matter anyway.
Thanks again for helpful and prompt replay.
Here is the info:
See notes section 5
CF9.0.2 came out with apsb12-15 applied.
Difference with CF10 is you can use CFadmin to change postparamlimit setting.
