Problem with commitment control and actgrp QILE

I'm experiencing strange problems with the use of commitment control for
programs in QILE actgrp

The problem is that when ending the commitment control I receive the CPF8355
message (pending changes active)  although all records were committed....? 

 

 

Here's the detail 

In my have CL program CL1   I have the commitment control started , this
program calls  RPG1 

RPG1 call RPG2 

All programs are ILE programs and run in the QILE -actgrp 

 

CL1... 

STRCMTCTL LCKLVL(*CHG)        (Default scope is *actgrp) 

Call RPG1   

      --> CALL RPG2  

                      file1 / file2 and file3 are opened under commitment
control.

           A change in a record from file3  is updated and committed in
rpg2.

 

When checking the commitment definition status from the job, I see my 3
files, 
file1 & 2 without any changes, file 3 showing 1 committed record....

 

So everything seems fine to me... but when returning to my cl-pgm, 

I do and endcmtctl , I receive the cpf8355 message... complaining about
pending changes... 

Although when looking at the commitment control status, NO pending records
are waiting...

 

 

What am I doing  wrong ?   any help or suggestion is welcome..
