Class NestedPathTag

java.lang.Object
  javax.servlet.jsp.tagext.TagSupport
      org.springframework.web.servlet.tags.NestedPathTag

All Implemented Interfaces:

javax.servlet.jsp.tagext.IterationTag, java.io.Serializable, javax.servlet.jsp.tagext.Tag

public class NestedPathTag

extends javax.servlet.jsp.tagext.TagSupport

Nested path tag, to support and assist with nested beans or bean properties. Exports a "nestedPath" variable of type String.

The BindTag will auto-detect the 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 nested multiple nested path tags.
