BPM: Howto access outputCollection from a multi instance sub process?

[hi-ko]

I would like to include in an email template the list of resolution, resolutionNote stored in a multi instance subprocess' outputCollection.
I guess I need to first create a variable to store the required object but how could I access the outputCollection in a following script task?
on the db the process outputCollection looks like this:

    "outputCollection": [
        {
            "processId": "656f6aec02143b973",
            "resolution": "Reviewed",
            "resolutionNote": null,
            "reviewerId": "6408b0a9550d66984",
            "reviewerName": "Reviewer 1"
        },
        {
            "processId": "656f6aec02143b973",
            "resolution": "Changes",
            "resolutionNote": "Here is my note as review2",
            "reviewerId": "6408b0f882f2664f2",
            "reviewerName": "Reviewer 2"
        },
        {
            "processId": "656f6aec02143b973",
            "resolution": "Changes",
            "resolutionNote": "my note as reviewer-3",
            "reviewerId": "6408b1303dd2d9f48",
            "reviewerName": "Reviewer 3"
        }
    ]​

Maybe you need to access it from the parent process, as accessing from the multi-instance sub-process does not make sense.

You should be able to access it as a variable, in your case it is $outputCollection. Then you can write some logic that will compose a string from it to be used in a text.

sorry - my bad. I tried to retrieve access from the parent process by running something like

bpm\createdEntity\attribute($reviewSubProcessAliasId, 'ReviewResultCollection')

but actually the outcome is already stored in the parents variable configured in the subprocess details ...

thanks for nudging me in the right direction
