Execution variable in end listener

[hassang]

Hi Zoltán,

Trying to get the value of the variable at an “end” execution listener of a service task wouldn’t work as the transaction is not yet committed to the database

Please see below post

Process variable history

Hi Otto, If you invoke your code shown above in the same transaction as the user task, it is not able to retrieve the data of the usertask, because the transaction is not yet committed to the database. You could mark the servicetask using your code as ‘async:before=true’. This would flush the transaction regarding the usertask to the database and you should be able to get the data then. Cheers, Christian
