Class NumericField

java.lang.Object
  extended by org.apache.tapestry.spec.BaseLocatable
      extended by org.apache.tapestry.AbstractComponent
          extended by org.apache.tapestry.form.AbstractFormComponent
              extended by org.apache.tapestry.form.AbstractTextField
                  extended by org.apache.tapestry.valid.ValidField
                      extended by org.apache.tapestry.contrib.valid.NumericField
All Implemented Interfaces:
IFormComponent, IComponent, ILocatable, ILocationHolder, IRender
public abstract class NumericField
extends ValidField

Backwards compatible version of the 1.0.7 NumericField component.

Parameter Type Read / Write Required Default Description
value Number R / W yes   The value to be updated.

When the form is submitted, this parameter is only updated if the value is valid.

When rendering, a null value will render as the empty string. A value of zero will render normally.

When the form is submitted, the type of the binding is used to determine what kind of object to convert the string to.

minimum Number R no   The minimum value accepted for the field.
maximum Number R no   The maximum value accepted for the field.
required boolean R no false If true, then a non-null value must be provided. If the field is not required, and a null (all whitespace) value is supplied in the field, then the value parameter is not updated.
displayName String R yes   A textual name for the field that is used when formulating error messages.
type String R yes   The class name used to convert the value entered. See NumberValidator.setValueType(String)

May not contain a body. May have informal parameters.
