Hello,
Looking at the documentation DOM status system | DataMiner Docs I tried to configure FlowLevel in status transitions to show transitions in a Stepper component.
In DOM Editor, i choosed the highest priority for flow level = 0 for the main transition of my state diagram.
In my LCA panel, i use a Stepper component, I expected to have
NEW --> PENDING --> CONFIRMED --> COMPLETED
But i have this result.
Can anyone tell me how to configure it for showing the main transition?
Thanks
Regards
Kévin
Hi Kevin,
I looked into this behavior and found the explanation: Whenever the stepper receives no history information for an instance, it 'guesses' the possible history based on the defined transitions. It also does this when the instance is already in its initial state, which is the software issue you are seeing here.
While we work on fixing this issue, you could prevent it from happening by adding 1 extra state. This state should be the initial state of the definition and should have no incoming transitions. This way, there is no path to get to this new state and the stepper will show the expected path.
Update: a fix for this issue will be available in DataMiner 10.3.0[CU16], 10.4.0[CU4] & 10.4.7
Hi Kevin,
The stepper component calculates the happy path based on the transitions & their flow levels, but also based on the state history of the instance. Is the instance in your example in its initial state or did it transition back from error to new? This could explain why you do not see the result you expected.
Hi Wout,
In my example, the instance is in the initial state “new”, i did not do any transition before.
Hi Kevin,
Can you also check if the ‘new’ state is configured as the initial one on the DOM Definition itself? When there is no state history, it should start from there.
In “dom editor”, if i edit my module then click on “Behavior Definitions…” button, then edit the behavior. The dropdown “Initial Status” selected is “New”.
Hi Wout, thanks.
While waiting for the fix, i applied the workaround you suggested.
I added a new extra state that has no incoming transition, then added a transition from this extra state to my “new” state and it works.
