Hi,

I was the one who started this thread, glad to see that it gets more attention.

Consider the following case;

<h:form>
        
        <h:inputText value="#{person.firstname}" required="true"/>

        <h:inputText value="#person.surname}" required="true"/>

        <h:commandButton value="Save">
                <f:ajax render="@form" execute="@form"/>
        </h:commandButton>

        <h:commandButton value="Reset" actionListener="#{pprBean.reset}">
                <f:ajax render="@form" execute="@this"/>
        </h:commandButton>

        <h:outputText value="#{person.firstname}" id="display" />

</h:form>

And the bean;

public class Bean {
        private String firstname;
        private String surname;

        ...
        public void reset() {
                firstname = null;
                surname = null;
        }
}

So there are two inputs bound to two properties and two buttons one to save one to reset.

- Enter a value for the first input, leave the second one blank.
- Click save button and validation will fail.
- Click reset button and although reset action is invoked first input still uses old value since it saves the local value in state and uses that instead of bean property value when rendering.

Setting immediate to true on reset button can't help here since input text will render submittedValue in that case instead of local value so still not the bean property.

One quick solution I can think of is not saving the value in state but there might be side effect I'm not aware of, probably if input is in UIData as UIData has special treatment to save/restore descendants.

There are also alternatives at;

But I think they're a bit complicated, one should not have trouble in clearing a form.
