Container Operation not working properly

Hi,

In my workflow,  container operation is not working properly sometime.

I am assigning agents from class attribute to workflow container . sometime the value is not correct.

scenario: class attribute - WFAGENT - value USABC

workflow container: WFAGENT_VAR.

assigning class attribute - WFAGENT to workflow container: WFAGENT_VAR.

instead of USABC, workflow container WFAGENT_VAR is having value as USWF-BATCH.

Please suggest.

Thank you.

Regards.
