Class FormDataNameInterceptor

Object
  FormDataNameInterceptor

All Implemented Interfaces:

INameInterceptor

public class FormDataNameInterceptor
extends Object
implements INameInterceptor

A INameInterceptor that qualifies all non-expression attributes that are expected to be expressions into valid expressions. This conversion is for Struts compatability; In Struts, the "property" property is used to specify which property on the action form should be rendered in a tag's HTML. These attributes are converted into expressions by qualifying them into the actionForm binding context.

For example, the dataSource attribute on a text box tag would be qualified into the actionForm context if the attribute was not an expression.
