I am having a problem with a form that has check boxes on it. If several checkboxes are checked it works great. If only one is checked then it gives the following error:

I can see that it is because instead of a list it now has a single string but I don't know how to handle this. Is there a way to force an object to be a list whether it is a list or a single string?
Yes. In your form, give the name a :list suffix: <input type=checkbox name="nums:list"> This forces creation of a list even if there is only one value.
