[jboss-user] [jBPM] - Form with multi-select yields single String instead of Collection

Martin Müller [https://community.jboss.org/people/martinmueller] created the discussion "Form with multi-select yields single String instead of Collection" To view the discussion, visit: https://community.jboss.org/message/759203#759203 -------------------------------------------------------------- Hey, when a user starts a process instance in the jBPM Console I'd like to display a form with a select input allowing multiple selection. I've got the form displayed properly with the multi-select box. However, when submitting the form the corresponding process variable only gets filled with a String containing the first selected value. Any other selected value is discarded, and I would have expected some Collection type instead of a String. The form is a basic HTML form inside the <process_id>.ftl file: <form action="complete" method="POST" enctype="multipart/form-data">   <select name="list" multiple="multiple">     <option value="value1">Option 1</option>     <option value="value2">Option 2</option>     <option value="value3">Option 3</option>   </select> </form> If I select "Option 2" and "Option 3" in this example and then start the process the list variable is set to a String "value2". How do I make it return a Collection with all selected values instead? Thanks in advance, Martin -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/759203#759203] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
