Backwards compatible version of the 1.0.7 ValidatingTextField component.

Parameter	Type	Read / Write	Required	Default	Description
text	java.lang.String	R / W	yes		The text inside the text field. When the form is submitted, the binding is only updated if the value is valid.
minimumLength	int	R	no	0	The minimum length (number of characters read) for the field. The value provided in the request is trimmed of leading and trailing whitespace. If a field is not required and no value is given, then minimumLength is ignored. Minimum length only applies if some non-null value is given.
required	boolean	R	no	false	If true, then a non-null value must be provided. A value consisting only of whitespace is considered null.
displayName	String	R	yes		A textual name for the field that is used when formulating error messages.

May not have a body. May have informal parameters.

1.0.8
