question

@Masashi01, A Trace resolves the items that are involved in events. An packed item as a subnode is not anymore the subject of an event. It is more an attribute than an object itself. You get a similar behavior for composed objects that are stored as drawsurrogate objects.

In reality you find this for example in each assembled product. You trace a computer, but you do not trace each component of a computer in a maintenance database. All you keep up to date is the table of content of the assembled computer.

Thank you for your explanation.

I understand that the packed items are assigned to attributes.

Does this mean that in order to resume tracing, I need to move them out of the attribute and convert them into objects that will trigger the event?

We would appreciate your assistance.

感謝。

今はだいたい理解しているけど、自分なりにやってみようと思うこともいくつかあるよ。
