refresh_on_change is not meant to be used explicitly in a tool's config file; it is an internal feature used by Galaxy to refresh pages as necessary, such as for conditionals. Also, dynamic_options has been deprecated in favor of the <options> tag. > So given above example (which is similar to what the original requester > asked), where to place the refresh_on_change option to get it working? If I'm reading your code right, this should be possible using the <options> tag only. First, select the dataset and then use something like for subsequent parameters: <options from_dataset="input_dataset"> <column name="name" index="0"/> <column name="value" index="0"/> <filter type="unique_value" name="unique" column="0"/> </options> Best, J. ___________________________________________________________ Please keep all replies on the list by using "reply all" in your mail client.
