Dan Haywood reopened ISIS-552:
------------------------------
> Upgrade to Wicket 6.10.0 introduced interference between required text fields
> and the Wicket viewer's veil.
> -----------------------------------------------------------------------------------------------------------
>
> Key: ISIS-552
> URL: https://issues.apache.org/jira/browse/ISIS-552
> Project: Isis
> Issue Type: Bug
> Components: Viewer: Wicket
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Priority: Minor
> Fix For: viewer-wicket-1.3.0
>
>
> Specifically, Wicket 6.10.0 (per
> https://issues.apache.org/jira/browse/WICKET-5289) now sets the HTML5
> "required" attribute. This causes HTML5 browsers such as Chrome to display a
> client-side pop-up.
> When the OK button is clicked, the Wicket viewer always displays the veil
> (see jquery.isis.viewer.wicket.js), and relies upon a page refresh to clear
> the veil.
> However, because the page is never submitted, the veil does not disappear.
> The only workaround is to resubmit the page, thus losing any text that might
> have been entered.
> This fix is to prevent Chrome from showing the pop-up by *not* setting the
> required flag in the Wicket viewer.
> ~~~
> An alternative solutino - that would preserve the pop-up - would be to change
> the way that the veil is rendered, by associating the Javascript callback
> with form.submit() rather than button.click().
