_Adhoc_Objects not passing to main workflow from subworkflow

Hello Team ,

We have scenario where in custom subworkflow creates an attachment and is assigned in the AdhocObjects container.

however , this is not getting cascaded back to the main workflow .

i am unable to assign the container binidng back to the main workflow as the subworkflow is determined dynamically .

the attachment/object is available in all the steps of the subworkflow , only missing when the main workflow is executed again in the subsequent steps.

please assist if am missing something .

thanks
