Hi all,
I have certain difficulties with merging different branches of flow.
My flow looks like following:
|-----------------------------------------------------------------------------|
| |---------------------------------------------------------|
|
| |-->>>>> |--------| |
|
| | | |
|
|------>>>> | | |
|
| | |
|
|------->>> | merge1 | |
|
| | | |
|
| |----->> | | |------------| --|
|---------| --|
| | | | | doByI1 |
| doByI2 |
~~----+--+------> |--------| --> |----------| --> |------------| --->
|---------| ------------->>> |--------|
| | | splitter |
-----------------------------------------------| | |
| | |----------| --> |------------| ---->
|-------------| ------+-->> | merge2 | -->
| | | doByI3 |
| doByI4 | | | |
| | |------------| --|
|-------------| --| |---> |--------|
| |---------------------------------------------------------|
|
|----------------------------------------------------------------------------------|
Both merge shapes have type MergePrioritized with eagerComplete = true.
The problem is when I run flow with some input which is correct, I
sometimes receive following error:
[error] a.a.RepointableActorRef - Error in stage [MergePrioritized]: Cannot
get element from already empty input port (MergePrioritized.in1(1037027355))
java.lang.IllegalArgumentException: Cannot get element from already empty
input port (MergePrioritized.in1(1037027355))
If I change eagerComplete value for of merge shapes I still see an error +
flow never ends. If I change it for both shapes, then error disappears, but
flow never ends.
I am wondering if it is design problem or I should look closer to the code
itself?
PS: If I replace MergePrioritized with MergePreferred, everything works
correctly without any problems.
Thank you in advance!
Regards,
Sergii
