------------------------------------

             Summary: Preview doesn't handle embedded JavaScript correctly
                 Key: JSPWIKI-1130
                 URL: https://issues.apache.org/jira/browse/JSPWIKI-1130
             Project: JSPWiki
          Issue Type: Bug
          Components: Editors
    Affects Versions: 2.11.0-M6
            Reporter: Ulf Dittmer


If "jspwiki.translatorReader.allowHTML = true", JavaScript can be inserted into 
a page and executed like this:

[{If page='SandBox' exists='true'

<script language="javascript">document.writeln("<b>User Agent: </b>" + 
navigator.userAgent);</script>}]

However, if preview is turned on during editing, executing the JavaScript 
interferes with the editor, replacing the editor page with the output of the 
code execution. I'm not sure whether it's possible to fix this while still 
trying to execute JavaScript. If not, disabling JavaScript during preview seems 
fine.
