[jira] [Comment Edited] (ARTEMIS-3858) navigating from session to related consumers/producers gives NPE

-----------------------------------------------------------------

observation #1:
most likely, the error handler is correctly called, but there is an error in that handler itself.
It should have used {{$scope.$ctrl.workspace}} (instead of {{$scope.workspace}})

observation #2:
the error handler is called because api call {{listProducers(java.lang.String, int, int)}} actually had a NPE
idem for {{listConsumers(java.lang.String, int, int)}}
the parameters seem harmless, but it seems that that actual value to compare with for the session is missing.
{{\{"field":"session","operation":"EQUALS","sortOrder":"asc","sortColumn":"id"}, 1, 10}}

>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>          Components: Web Console
>    Affects Versions: 2.22.0
>            Reporter: Erwin Dondorp
>            Priority: Minor
>
> on an Artemis cluster, go to page Sessions.
> then click on the value in either columns "Consumer Count" or "Producer Count".
> see the resulting error message "could not invoke list sessionsjava.lang.NullPointerException : no mapping for value". the resulting consumer/producer table is always empty.
> the browser console shows the error message "Uncaught TypeError: $scope.workspace is undefined"
> I should be able to create a PR for this (but feel free to beat me on that)
