Greg and rc; I've been trying to keep up with the latest changes in the FormValues table, and am running into one issue with the upgrade script: https://bitbucket.org/galaxy/galaxy-central/src/714afada18de/lib/galaxy/mode... During the conversion of the field from a list to dictionary, this assumes all of the values are strings, and strips out any quote characters. I'm using this table to store more complex objects like dictionaries, and they are disrupted by that change. Is this step necessary? The to_json_string call should quote any of these characters appropriately. This patch gets rid of the quote stripping so should be safe to make the conversion without changing content: https://bitbucket.org/chapmanb/galaxy-central/changeset/920527658e04 Thanks, Brad
