Hi!

I tried to embed links in a TreeViewer, but encountered the following problem.
Embedding links works fine, as long as they do not include '&'. If any part of the html contains an ampersand('&') however, the Viewer can not display the item and an IllegalArgumentExceptino is thrown:

Text:

<a href="/testing?servicehandler=7d880b02docsDLTest5.pdf&cid=de8c4e9&filename=Test5.pdf" >Test5.pdf</a>

Exception:

java.lang.IllegalArgumentException: Failed to parse markup text
<...>
Caused by: org.xml.sax.SAXParseException: The reference to entity "cid" must end with the ';' delimiter.

How can I turn this reference behavior off or escape my html correctly?

Thanks for any advice,
Tibu

Hi Tibu,
the MarkupValidator is using javax.xml.parsers.SAXParser internally to
check if markup is correct (valid XHTML). Parsing failed if there is '&'
character as it indicates entity start. Please file a bugzilla about
this issue.
Thanks,
Ivan

I created Bug 416451[1]

For the interested:
I managed to work around the issue.
I replaced the ampersands in the original link with %26 and registered a "LinkListener" to the tree, as described in the 2.1 New and Noteworthy[2]. When the listener is activated it takes the URL from the event (event.text), replaces the %26's again and sets the original URL in an invisible Browser-Widget. This triggers the client browser to start the download.

Greetings
Tibu
