[galaxy-dev] History will not refresh after workflow submission via the API

Hi devs!   After updating my local instance to changeset 19cbbaf566216cb46ecc6a6d17e0f1e0ab52978e my tool which submits a workflow via the API and set force_history_refresh to TRUE does not refresh the history anymore.   The job is submit via DRMAA to SGE. Unfortunately the job seems to run forever because it is still in yellow state (even after SGE tells Galaxy that the job has finished. As soon as I refresh the history manually the according history entries get green and all entries for the submitted workflow are shown.   I have no idea where I can have a look at. If you need any further information let me know!   Thanks for your help in advance!   Cheers, Sascha
