I would like to have an illustrative explanation about the difference between getValue()
and getLocalValue()
methods of UIInput
components in the aspect of performing multiple field validation: jsf validate two fields in one time.
What is the difference in usage of this methods if the fields are already validated? The ValueHolder
API documentation is not very helpful in answering this.
If the UIInput
component has been validated beforehand and is marked invalid (i.e. isValid()
method returns false
), then the getLocalValue()
returns null
, but the getValue()
returns the old model value, if any. If it's marked valid, then both returns the same value, namely the submitted, converted and validated value.
You'd like to add a check on isValid()
beforehand. You may find the source code examples of the OmniFaces multiple field validators helpful. See the ValidateMultipleFields
source code link at the bottom of the <o:validateEqual>
showcase page.
