AbstractTransformerBehavior breaks ajax requests in IE8
-------------------------------------------------------
Key: WICKET-4464
URL: https://issues.apache.org/jira/browse/WICKET-4464
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.4.20
Reporter: Robert Keller
AbstractTransformerBehavior sets ´webResponse.setContentType("text/" +
getMarkupType(component) + "; charset=" + encoding);´
This delegates to the page and in our case usually returns "text/html".
In ajax-request this overwrites the required setting for ajax "text/xml". If
IE8 receives an ajax-response as "text/html" then in wicket-ajax.js:1049 the
xmldoc = t.responseXml is null and the error is:
"ERROR: Wicket.Ajax.Call.failure: Error while parsing response: Could not find
root <ajax-response> element".
This error was created by https://issues.apache.org/jira/browse/WICKET-3633.
Possible un-/fixes:
- Changing the markuptype on page level to "xml" in ajaxrequests might break
functionality.
+ let only AbstractTransformerBehavior consider ajaxrequests and then set xml
+ at least: make
org.apache.wicket.markup.html.border.MarkupComponentBorder.getMarkupType(Component)
protected and not final!
