 Map can be used the same way, without any "adapter".
I think type information is useless in this case ( "script" doe's not use
it ).
Are "dynabeans" used as some kind of workaround for "not map enabled"
frameworks  ?

i don't how you could use them but i don't think that this is the reason why they were developed.

AFAIK they act as adapters (for bean-centric environments) for data which isn't in beans. for example, they can be used to wrap a resultset so that it appears to be beans. if the bean-centric environment uses beanutils for it's introspection then the dynabean wrapping the resultset will look and behaviour like a bean.

(i'm not a dynabeans expert so hopefully i'll be corrected if i've gone wrong.)

a map could act as a pseudo-bean by having each key-value pair act as a
pseudo-property. the name of the property corresponds to the key (from

the

pair) and the property value corresponds to the value (from the pair).

FYI, this is part of what [clazz] is trying to achieve.
