The parameter values of the RAW decoder of the record/set of was faulty:
The value of the first_call parameter was wrong. The number of elements was
passed intead of the first call indication.

Meaning of the parameters:
 - sel_field:  * union -> the selected field to be decoded
               * record of -> the number of the element in the list

 - first_call: * record of -> indicates that the decode is called for the
                              first time or it is a repeated call
