[jira] [Commented] (TAP5-1730) Ajax Zone is improperly reloaded
when a mixin submits form via JavaScript
[ https://issues.apache.org/jira/browse/TAP5-1730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13136352#comment-13136352 ]
Lenny Primak commented on TAP5-1730:
------------------------------------
I think there should be performSubmit() or similar function that takes the submitting element
and calls setSubmittingElement() so there is a standard way for JavaScript to invoke forms in a zone,
and it should be documented somewhere as well.

> Key: TAP5-1730
> URL: https://issues.apache.org/jira/browse/TAP5-1730
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.3, 5.4
> Reporter: Lenny Primak
> Priority: Minor
>
> Tapestry reloads the zone improperly if JS code
> Improperly submits the form. It should at least give some kind of an error
> or a warning when happens.
> Right now, it fails silently leading to an improper zone reload,
> which leads to weird errors when app is running subsequently.
> If form..setSubmittingElement(() isn't called before form.onsubmit(),
> the Tapestry silently fails and the zone is improperly reloaded.
> ---------------------------------------------------------------
> There was an addition of one line:
> $(this.formId).setSubmittingElement($(this.elementId)); // *** ADDED otherwise zone gets improperly reloaded
> $(this.formId).onsubmit(); // Submit Ajax form
> If you don't add the first line, the form is reloaded improperly after the zone update,
> so it doesn't work the second time.
> This is not documented anywhere, and really hard to debug.
