org.springframework.web.servlet.tags.NestedPathTag
public class NestedPathTag
Nested-path tag, to support and assist with nested beans or bean properties in the model. Exports a "nestedPath" variable of type String in request scope, visible to the current page and also included pages, if any.
The BindTag will auto-detect the current nested path and automatically prepend it to its own path to form a complete path to the bean or bean property.
This tag will also prepend any existing nested path that is currently set. Thus, you can nest multiple nested-path tags.
Thanks to Seth Ladd for the suggestion and the original implementation!
