[jira] [Commented] (TAP5-2359) LinkSubmit submits form twice on Internet Explorer 11/Windows 8.1

["Jochen Kemnade (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-2359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14049202#comment-14049202 ] 

Jochen Kemnade commented on TAP5-2359:
--------------------------------------

Yes, the {{form.trigger("submit")}} will actually submit the form. At least on Firefox {{form.element.submit();}} is never executed. I wonder why IE11 executes it because the handler that catches {{form.trigger("submit")}} should not return a trueish value but either {{false}} or {{undefined}}.
Do we actually still need the {{form.element.submit();}}?

>             Project: Tapestry 5
>          Issue Type: Bug
>    Affects Versions: 5.4
>            Reporter: Michael Wyraz
>
> Affected Version is (at least) T5.4-beta-6. I have a simple form that is submitted via linksubmit:
>     <t:form>
>     	<t:linksubmit>submit</t:linksubmit>
>     </t:form>
> On Internet explorer the form is submitted twice. This also causes a race condition so it is not 100% reproducible (but ~80%) and sometimes submits the form once with and once without t:formdata (rare case).
> We tracked it down to:
>       if (form.trigger("submit")) {
>         form.element.submit();
>       }
> form.trigger("submit") submits the form the first time, form.element.submit() the second time.
