> Hi, everyone.
> Suppose, I have a Map in my form, called "person": 
> private Map person;
> That Map has (besides other entries), a entry called "addresses", which is in
> turn a Map again. This "addresses" Map has several addresses of the person. One
> of those addresses has key "home" and String value of home address.
> I want to render a text input field for the "home" address - I use EL syntax, no
> brackets (it renders element correctly):
> <nested:text property="person.addresses.home"/>
> In html this element is _being rendered correctly_, including correctly
> displayed value of home address, taken from the "addresses" Map.
> However, if I submit this form with changed value of address, it's not being
> populated.
> I wrote my own implementation of "addresses" Map to see what's happening, and I
> saw that no put method is called at all (only get() while rendering the element).
> So then I also made custom implementation of "person" Map and saw there, that
> while submitting, it calls get("addresses") (which returns "addresses" Map) and
> that's all. 
> So apparently, BeanUtils sees, that it retrieved a Map and stops processing, not
> generating any exceptions BTW.
