Major Description
PortletWindow widget (/javascript/jetspeed/widget/PortletWindow.src.js) tries to retrieve script source which can be embedded in the script tag or retrieved from the remote url which is set in "src" attribute to "fix" some script sources (such as attaching events or document.write stuff) by proper dojo functions.
The "_fixScripts" function in PortletWindow.src.js replaces some problematic script codes which can screw up desktop page.
For example,
(addEventListener|attachEvent) -->
jetspeed.postload_(addEventListener|attachEvent),
(document.write|document.writeln) --> jetspeed.postload_docwrite
(location.href) --> jetspeed.setdoclocation.
However, because it fails to retrieve script sources from different domain urls for security reasons, it fails to render the portlet content.
