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();}}?
> LinkSubmit submits form twice on Internet Explorer 11/Windows 8.1

> Key: TAP5-2359
> URL: https://issues.apache.org/jira/browse/TAP5-2359
> 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.
