[OmniFaces utilities (2.0)] Signals JSF that the validations phase of the current request has failed

---

[OmniFaces utilities] The validationFailed() method signals JSF that the validations phase of the current request has failed. This can be invoked in any other phase than the validations phase. The value can be read by isValidationFailed() in Java and by facesContext.validationFailed() in EL.

[OmniFaces utilities] The isValidationFailed() method returns whether the validations phase of the current request has failed.

Method:

See also: Faces#getContext()

Usage:

JSF allows us to programmatically signal that validation failed via FacesContext#validationFailed() method. Basically, this method sets a flag, named validationFailed, which is by default false. For example, when an input validation fails in Process Validations phase, JSF will invoke this method, as below:

FacesContext fc = FacesContext.getCurrentInstance();

fc.validationFailed();

OmniFaces comes with a shortcut for this method, named Faces#validationFailed().

import org.omnifaces.util.Faces;

...

Faces.validationFailed();

or,

import static org.omnifaces.util.Faces.validationFailed;

...

validationFailed();

OmniFaces also comes with an OmniFaces utilities that returns the value of the validationFailed flag, named Faces#isValidationFailed().

Method:

See also: Faces#getContext()

Usage:

import org.omnifaces.util.Faces;

...

boolean isvalidationfailed = Faces.isValidationFailed();

or,

import static org.omnifaces.util.Faces.isValidationFailed;

...

boolean isvalidationfailed = isValidationFailed();

This method is a shortcut for plain JSF:

FacesContext fc = FacesContext.getCurrentInstance();

boolean isvalidationfailed = fc.isValidationFailed();
