Filenet - How to get the Property values in Workflow group

Question

I have 2 Filenet Workflows where the firstWF takes the userids and store it on document property as String separated by comma. What I want from my SecondWF is that it should take that userids and assign it to workflow group when secondWF launch. I think it could be possible if it would be any step except Launch step on SecondWF by converting String to array & then assign it to Workflow group but I am unsure how to do it at the Launch step of SecondWF.

Answer 1

1. to create a STRING data field dfA in WF2 to store the comma-separated string.
2. to mapping property from document to workflow launch step (expose dfA) using entry template (or you can use CREATE function in WF 1).
3. on Launch step property page -> Assignments tab, use the Expression Builder to parse dfA and prefix each cell value with '@' and append to your WfGrp (participants array type) field.

Done.
