> Key: WICKET-2553
> URL: https://issues.apache.org/jira/browse/WICKET-2553
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.2, 1.4.3
> Reporter: Daan
> Assignee: Igor Vaynberg
> Fix For: 1.4.4, 1.5-M1
>
>
> In SVN revision 815602
> (http://www.mail-archive.com/[email protected]/msg13879.html) some
> new code is added.
> This introduces a new bug where a null button is added to the form. This
> gives an error in Safari and Firefox and results in a form that doesn't
> submit.
> {code}
> if (submitButton!=null) {
> try {
> var btn = document.createElement("<input type='hidden'
> name='"+submitButton+"' id='"+iframe.id+"-btn' value='1'/>");
> } catch (ex) {
> var btn = document.createElement("input");
> btn.type="hidden";
> btn.name=submitButton;
> btn.id=iframe.id+"-btn";
> btn.value="1";
> }
> }
> form.appendChild(btn);
> {code}
> In the code above, form.appendChild(btn) is called. In my case, the btn is
> not created yet, because the "if" statement is skipped (submitButton == null).
> This results in an error.
> I think the form.appendChild(btn) line needs to be inside the "if" block, so
> it is not called when the btn does not exist.
