Ufuk Altin created WICKET-5519:
----------------------------------
Summary: ContributorListenerCollection behaves differently after
upgrade
Key: WICKET-5519
URL: https://issues.apache.org/jira/browse/WICKET-5519
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 6.7.0
Reporter: Ufuk Altin
I used Wicket 6.6.0 and upgraded to 6.14.0 (and tested it also on 6.7.0). In
WicketApplication I have the following code within the init()-Method
{code:title=WicketApplication.java|borderStyle=solid}
@Override
protected void init() {
super.init();
getHeaderContributorListenerCollection().add(new IHeaderContributor() {
private static final long serialVersionUID = 442899940490126649L;
@Override
public void renderHead(final IHeaderResponse response) {
response.render(WicketUtils.composeMetaItem("X-UA-Compatible",
"IE=edge"));
response.render(WicketUtils.composeMetaItem("Content-Type",
"text/html; charset=UTF-8"));
response.render(WicketUtils.composeMetaItem("Expires", "0"));
response.render(WicketUtils.composeMetaItem("Cache-Control",
"no-store, no-cache, must-revalidate, max-age=0, private"));
response.render(WicketUtils.composeMetaItem("Pragma", "no-cache"));
}
});
}
{code}
Which renders metadata in the html head.
This causes, after the update to Wicket 6.14.0 and 6.7.0, the Wicket Debugger
to throw an Error after I do an ajax request. The error is not thrown if the
above code is removed.
The Error is the following:
{quote}
{color:red}
ERROR:
{color}
Error in parsing: This page contains the following errors:error on line 22 at
column 8: Opening and ending tag mismatch: meta line 0 and head
Below is a rendering of the page up to the first error.
{quote}
Would it be possible to put the above metadata in HTML and what would be the
difference?
{code:title=Template.html|borderStyle=solid}
