Dear Galaxy Devs I would like to display some custom data that will load up dynamically based on logged in user and I could get simple dynamic_options working, however how would I grab logged in user id, before the execution of main tool. I hope there would be a way to do this. I have tried dynamic_options="load_dynamic_values($__user_id__) in xml wrapper but did not work. I know $__user_id__ can be passed to the tool as command line arguments, however, my issue is to read user id even before the execution of main tool. Thanks for your help guys. Regards Khushi
