Question

Is there any way I can validate a jsf input text that is readonly but the value is changed upon some other events triggered?

Answer 1

I have solved this problem with a workaround. I have added an inputHidden field that has the required attribute true that will not appear on the interface, but will be validated:

<h:inputHidden value="#{bean.value}" required="true"
                    requiredMessage="Data must be entered" />

The value of bean.value is changed by other event, and at some reRender on the inputHidden, the validation takes place.
