Now, the idea is to use the API also for implementing #2218. While testing out this it was discovered that in some cases the implementation of the `SourceItemTransformer.transform()` method would return incorrect results if called more than once. The main suspect is the transitions from Extract to Derived bioassay (in both directions) that uses the `CollectExtracts` to keep track of extracts in order to later be able to select the correct path when continuing up- or downstream. The collected extracts need to be cleared each time the `transform()` method is used otherwise the transformer will include extracts from the first call also on the second call, and so on. There is no simple way to test this yet, so I think the first thing is to implement a test case." defect closed major BASE 3.17 core fixed
