Description

Problem is caused when refreshing markup using Ajax and in data is special character (￾).

Error occurs in my project everywhere when refreshing markup using Ajax where this special character occurs.

I create and attach quickstart project which reproduces this problem in simple way: changing markup through hiding/showing TextField by ajax button.

 

Steps to reproduce problem:

1. Download and run attached quickstart project

2. Enter to TextField symbol presented under "Insert this string for error..." label:

3) Click „Regular submit” twice (this causes component to refresh, but doesn’t cause error)

4) Now click „Ajax submit” twice – this causes button to not refresh markup and show error:

 

ERROR: Wicket.Ajax.Call.failure: Error while parsing response: Error: Invalid XML: <?xml version="1.0" encoding="UTF-8"?><ajax-response><component id="field3" ><![CDATA[<input value="" name="field" id="field3"/>]]></component></ajax-response>
