Hi all, I'm working on a tool where the <repeat> tag looks like an elegant solution - however I want to limit the number of repeats to be 1, 2 or 3. i.e. I want to set min="1" and max="3" attributes for the <repeat>, based on analogy to the <param> tag. Is this possible, but not documented here? https://bitbucket.org/galaxy/galaxy-central/wiki/ToolConfigSyntax In terms of the GUI, I'd like the page to preload with as many entries as the min setting (zero by default), and disable the add button once the max setting is reach (default no limit). (Alternatively you could validate the max/min when the form is submitted by clicking the execute button, but that seems less user friendly.) If this isn't already possible, would it be generally useful to add this? Thanks, Peter
