This page is a quick page for capturing the issues we're seeing reported about this portlet on-list.

This page may very quickly outlive its usefulness (issues get resolved, get translated into JIRA items) but first pass it's an attempt to gather them...

Working in IE? ClassCastException?

In 2-5-patches, it displays the root directory's files and folders correctly in Mozilla, but not in IE (no HTML markup at all). I haven't looked at the code very closely but that seems very strange to me (smile)

Also, when I attempt to upload a file, it throws the following exception:

org.jasig.portal.PortalException: java.lang.ClassCastException

Scalability?

We've found it chokes when trying to display a large number of files/folders. We're exploring options now on rewriting a portion of the UI so it doesn't have to rebuild that list each time, or just using Novell's NetStorage.
