Is it possible to preselect one of the options from the select menu?
I have this UI Component:
<h:selectOneMenu value="#{authenticateController.country}">
<f:selectItems value="#{constants.countrySelectMenu}" />
</h:selectOneMenu>
The values of #{constants.countrySelectMenu} are a list of country ID - country name pairs.
Is there a way to render the list with a preselected value or at least is there a work-around to get this done?
Just preset the property behind <h:selectOneMenu value> with the desired value. You can do it in for example the bean's (post)constructor, action(listener) method, etc.
In your specific example, thus e.g.
public class AuthenticateController {
private String country;
@PostConstruct
public void init() {
country = "NL";
}
// ...
}
It works exactly the same way for all other UIInput components like <h:inputText> and so on. The input component's value itself simply represents the (pre)selected/checked/filled value.
