This patch, unfortunately, has the unintended consequence of breaking the 
size= parameter of the form-property, which allows you to create an array of 
beans before entering a form.  Since you return null if the initialization 
string is null in the new getScalar method, the array will be initialized to 
an array of null rather than an array of objects.  

If you depend on strings being null before form submission, I suggest you 
implement an explicit reset() for a subclass.  

I will say that in general, depending on the presence or absence of a 
parameter to detect state is a bad idea IMHO.  You could do it with greater 
transparency by coding an explicit hidden state parameter in the form.
