Hi all, I have looked and I found only one place<http://www.mail-archive.com/galaxy-dev%40lists.bx.psu.edu/msg04237.html> where this question was asked back in 2012 but no answers. My question is how can I specify a dataset in a shared library without importing the dataset to my current history? Ideally it would be something like param< type="history_dataset" ...> but if that isn't an option is there a way to plugin ajax or some other scripting to grab options to fill the list?
