Re: Dynamic list of radio buttons
Creating the html forms itself is not a problem. However i would like to have a dynamic amount of radio button sets. So to use this radio buttons within a loop with dynamic size. So how to set the name of the radio button? For each set one value should be selected. So the name must be unique for each set. And how do I get the values of all this into my Action class? I'd prefer having a hashmap there. So the problem with the hashmap is not about the values which can be selected, but the form data being submitted.
