-------------------------------------
Summary: FileUpload: IE9 is not redirecting to response body while
uploading file using wicket modal page(embedded within a JSP)
Key: WICKET-5216
URL: https://issues.apache.org/jira/browse/WICKET-5216
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.5.5
Reporter: Chandan Sethi
In case of IE9 while processing multipart AJAX request we get XMLDocument as
NULL. So wicket uses its helper JS functions Wicket._htmlToDomDocument() and
Wicket._createXmlDocument() functions to load XML document. The text used by
these two methods is of the following form
"- <ajax-response>\r\n- <redirect>\r\n- <![CDATA[ /wicket/page?17\r\n ]]> \r\n
</redirect>\r\n </ajax-response>"
The function Wicket._htmlToDomDocument() trims the above text and replaces all
occurrence of ‘/r/n-’. The resultant text (i.e. ‘‘- <ajax-response> <redirect>
<![CDATA[ /wicket/page?13 ]]> </redirect> </ajax-response>’) is then passed to
function Wicket._createXmlDocument() for creating XML Document. However
function Wicket._createXmlDocument() is throwing error as it is unable to load
XML document from the provided text. Function Wicket._createXmlDocument() gets
failed to load XML document from text because text has an error i.e. it
contains extra ‘-’ at the start of the text. Due to the error wicket does not
found <ajax-response> element in the response. Hence IE9 is not able to process
the response.
If we remove extra ‘-’ from the text then wicket loads XML document
successfully and IE9 gets redirect to response successfully.
Note: In case of IE8 we get appropriate XMLDocument therefore wicket does not
call helper JS functions to get the XML Document.
