I use 2 activities in button activity to create child case: createWorkPage and pxAddChildWork (the way I complete paramters is shown on screenshot). Child case creates by the button click in Clipboard (the data is written in pyWorkPage.pxCoveredInsKeys) but the child case is not run. Also, I get error after page refreshing: "The current assignment and work object do not refer to one another". Then child case list appears(shown on screenshot). I run one of these child cases and open Clipboard. In Clipboard appears pyWorkCover with the parent case link. So, we can see that these cases are related. Can you tell me why the error appears? And how can I run child cases automatically after its creation?
