Examples of javax.faces.application.FacesMessage

javax.faces.application.FacesMessage
FacesMessage represents a single validation (or other) message, which is typically associated with a particular component in the view. A {@link javax.faces.application.FacesMessage} instance may be createdbased on a specific messageId. The specification defines the set of messageIds for which there must be {@link javax.faces.application.FacesMessage} instances.
The implementation must take the following steps when creating FacesMessage instances given a messageId:

        VariableResolver vr = fc.getApplication().getVariableResolver();
        AdvancedFilter af = (AdvancedFilter) vr.resolveVariable(fc, "advancedFilter");
        
        DataFilterEntry entry = af.getEntry();
        if (entry.getOperator() == null) {
            fc.addMessage("msg", new FacesMessage("Operator is not filled!"));
        } else if (entry.getOperator().needsValue() && Utilities.isEmpty(entry.getValue())) {
            fc.addMessage("msg", new FacesMessage("Value is not filled!"));
        } else {
            af.addCurrentEntry();
        }
        
        return current();
