Submitting form with a zone or not, depending on submit button choosed

Hi,

I would like to be able to refresh a zone of a form if the user clicks one
button, or simply submit the form with a full page change if the user
clicks on another button.

But the zone attribute is on the "t:form" component, and not on the
t:submit component.

Did somebody see a way to achieve this behaviour ?

Thanks.
Nicolas.

Thank you so much, it works very well.

For the record, here is my test code :

public class Ajax {
    @Property
    private String selectValue;

    @Property
    private String fieldValue;

    @Inject
    @Property
    private Block formBlock;

    @OnEvent(value = EventConstants.SELECTED, component = "submitBtn")
    public void submitFromButton() {
        reloadPage = false;
    }

    private boolean reloadPage = true;

    public Object onSuccess() {
        fieldValue = fieldValue + " / "
                + Long.toString(System.currentTimeMillis());
        if (reloadPage) {
            return formBlock;
        } else {
            return Index.class;
        }
    }

}

<html t:type="layout"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd"
xmlns:p="tapestry:parameter">

	<t:zone id="updateZone">
		<t:delegate to="formBlock" />
	</t:zone>

	<t:block t:id="formBlock">
		<t:form zone="updateZone">

			<t:select model="literal:1,2,3" value="selectValue"
				onChange="this.form.fire(Tapestry.FORM_PROCESS_SUBMIT_EVENT)" />

			<t:textfield value="fieldValue" />

			<t:submit t:id="submitBtn" />
		</t:form>

	</t:block>
</html>

This JavaScript snippet doesn't trigger an AJAX form submission. Use  
$(formId).fire(Tapestry.FORM_PROCESS_SUBMIT_EVENT);, where formId is
the client id of your form. That's exactly how Tapestry itself does AJAX  
form submissions.

Hi,

Maybe the explanation of my problem was not clear enough (or there is no
solution ?)...

So i have the following template :

<t:form>
  <t:select model="selectModel" value="selectValue"
onchange="this.form.submit()" />
  [... other form inputs and data ...]
  <t:submit t:id="submitBtn" />
</t:form>

and on the java side i have

@OnEvent(value = EventConstants.SELECTED, component = "submitBtn")
public void submitFromButton() {
    reloadPage = false;
}

private boolean reloadPage = true;

public Class onSuccess() throws DAOException {
    if (reloadPage) {
        return null;
    } else {
        return ViewCart.class;
    }
}

I would like to avoid the full page reload when the select changes, and to
just update a zone (which will be the form itself).

Thanks for any help !

Nicolas.
