Thanks for your response.
I have changed CP parameter's place in script, I have moved it just after CorrelationParameter_9 so it is written upper in script now and it works. However, I have another problem :)
When I run script there is no error in Controller. It says everything ok but when I look to real system, it only does first user's actions, for other users it does not upload excel file (last action). I think the parameters that I send to system are not true. Since when we look server logs, it gives NullPointerException.
I do not know which parameter/s are false :(
Is there anyonewho can help me?
