How does DataMiner know the child DVE elements of a parent element?

Where does DataMiner keep the mapping between a parent element and its children?

I know that a DVE is generated for every row in a table with the correct "dve-features".

I would like to better understand a case where some of my child elements are no longer stopping after the parent is stopped.

The DVE mapping in Cube is done by looking at certain properties in the ElementInfoEventMessage. Below is an example of a child DVE, it has a DveParentDmaId, DveParentElementId and IsDynamicElement set true. Perhaps you can use this info to check if the active DVE elements in your case are linked as expected to the DVE main that was stopped. (Check if the ParentID is actually the one of the stopped Element.)
