Currently AbstractForm (located in betacms-portal-commons module ) provides one map where values from all input fields are stored. However they are some cases where forms contain some input fields which do not correspond to content object properties, like email confirmation or password confirmation input field.

When form infrastructure tries to store these values in to a content object, an exception is thrown as some values correspond to properties which are not defined in content object's type.

Specify another map where these values could be stored and eventually they won't interfere with form's mechanism.
