Wicket.Ajax: An error occurred while executing Ajax request:SyntaxError: An invalid or illegal string was specified
XML Parsing Error: mismatched tag. Expected: </iframe>.
Row Nr. 1, Column 202:
I found out that Wicket’s Ajax code is responsible for those problems.
The iframe tag isn’t closed. This is fine for HTML5, but not for XHTML5.
I have attached a quite minimal Wicket project were the problems can be examined:
Open your browser’s console and upload any file on localhost:8080.
A patch which fixes this issued is attached. Thanks for your help.
