I have a structure data type -> Product with properties -> Id, Name, Item
where Item is a structure with properties -> Id, Name.
Item has a 1:N (one or more) cardinality inside Product.

I have created an activity "EnterProduct" with out data mapping for id, name and items (item is selected in data path).

My model deploys successfully. When I goto my workflow -> EnterProduct activity I can see the fields to enter product information and a table for entering the items(table columns- id, name) and a + and - sign to enter rows.
I enter the values for product and items, but when I try to complete the activity, I get error message as - "Element must be detached."
and at tomcat console I get following exception trace -
org.eclipse.stardust.common.error.InternalException: Element must be detached.

Hi AG,

Could you either share the model (XPDL) or at least a screen shot of the "EnterProduct" activity's out data mappings and the structured data definition of "Product"?
