Returns a nested path with a dot, i.e. "address.", for easy building of concatenated paths. Default is an empty String.

public void pushNestedPath(java.lang.String subPath)
Errors
A Errors.popNestedPath()
call will reset the original
nested path before the corresponding
pushNestedPath(String)
call.
Using the nested path stack allows to set temporary nested paths for subobjects without having to worry about a temporary path holder.
For example: current path "spouse.", pushNestedPath("child") -> result path "spouse.child."; popNestedPath() -> "spouse." again.

This is a convenience method to avoid repeated reject(..)
calls for merging an Errors

Note that the passed-in Errors
instance is supposed
to refer to the same target object, or at least contain compatible errors
that apply to the target object of this Errors
instance.

and the object itself as 'objectName'.
Note that the Map is constructed every time you're calling this method. Adding things to the map and then re-calling this method will not work.
The attributes in the model Map returned by this method are usually
included in the ModelAndView
for a form view that uses Spring's bind
tag in a JSP,
which needs access to the BindingResult instance. Spring's pre-built
form controllers will do this for you when rendering a form view.
When building the ModelAndView instance yourself, you need to include
the attributes from the model Map returned by this method.
