Since 4.1

The ace:clientValidateValueRange component validates the input of the enclosing component by allowing only numeric values within the defined minimum, maximum, or range to be submitted.

The ace:clientValidateValueRange component can be used to validate the following:

  • A minimum value (minimum attribute)
  • A maximum value (maximum attribute)
  • A value range (minimum and maximum attributes)
See the ICEfaces Showcase Live Demo of this component, complete with source code.

Getting Started

<html ... xmlns:ace="">
        // Validate that the entered value is not greater than 10. 
        <ace:textEntry id="textEntry2" value="#{clientValidateValueRangeBean.value2}" 
            label="Input Value " labelPosition="left" size="8">
            <ace:clientValidateValueRange maximum="10" />
        // Validate that the entered value is within the range of 10 to 20.
        <ace:textEntry id="textEntry3" value="#{clientValidateValueRangeBean.value3}" 
            label="Input Value " labelPosition="left" size="8">
            <ace:clientValidateValueRange minimum="10" maximum="20" />

minimum required value of the input. If not defined the minimum value is not verified.

maximum allowed value of the input. If not defined the maximum value is not verified.

Validation Behaviour

  • Client validation occurs initially when the component value is attempted to be submitted to the server, either via an ace:ajax partial-submit or a full form submit. If the client validation fails the submit to the server is aborted and the appropriate error message is displayed in an associated ace:message, ace:messages, or ace:growlMessages component (without requiring a server-roundtrip). Thus, a form submit with multiple components is processed atomically and will be completely aborted if any of the components within it fail client validation.
  • Before submitting an entered component value the first time (either via full form submit, or an ace:ajax partial-submit), the user can tab through components in the form without triggering annoying validation messages - they won't get bugged before having the chance to actually enter a correct value.
  • However, once a component is marked invalid by a previous validation failure, it is eagerly validated: As soon as the user has entered the necessary value, the error message is removed, without requiring a form submit.
  • Client validation supports the "immediate='true'" attribute on ace:pushButton and ace:linkButton. When "immediate='true'" the button submit will occur regardless of whether one or more components in the form are failing client validation.
