[saria-sarsoura.2014]

Hello,

It worked for me, when I called    http://localhost:8080/jbpm-console/rest/task/query?potentialOwner=saria  [GET]

[greenday_ra]

More information

if there is no process instance, running this command make this result

http://localhost:8080/kie-wb/rest/task/query?potentialOwner=azizi

-> <task-summary-list/>

if I start a process that have a task with actor set to user = azizi

by running that rest command, I receive error

SAXException2 thrown with message 'class org.jbpm.services.task.query.TaskSummaryImpl nor any of its super class is known to this context.'

...

if I run that rest command with another user name

i receive empty task list

so error is only with my BP with my user

any idea?

I attach my project too,

today I get the last version kie-wb-distributions-6.1.x from github and make it again

error still exist!!!

[greenday_ra]

problem resolved by downloading installer version,

it seems there is a problem in my maven local .m2 repository and I must re download all jbpm dependency again to compile a new one.

[swiderski.maciej]

this was fixed few weeks ago by backporting solution from upstream (6.2.0-SNAPSHOT - master) version and will be included in upcoming 6.1.0.Final version
