Subject Re: Dynamic list of radio buttons
Date Sat, 24 Apr 2010 22:50:44 GMT
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.
