Hi This is not really a Dancer problem, but something that I am missing when changing from CGI to Dancer + TemplateToolkit. Basically: - I have a form with an array of checkboxes - that form gets submitted - some results are shown, together with the form for resubmission The question is, how do I keep the checkboxes checked (or not) accordingly with what the user picked before submitting it? For reference, CGI called this behavior as stiky: By default the CGI module implements a state-preserving behavior called "sticky" fields. The way this works is that if you are regenerating a form, the methods that generate the form field values will interrogate param() to see if similarly-named parameters are present in the query string. If they find a like-named parameter, they will use it to set their default values. Thank you ambs
