Matt Wringe commented on GTNWSRP-84:
------------------------------------
Looking into this a bit more, if you load one instance of the E2 Oracle portlet on the
page (ie the Lotto number portlet) and reload the page, then it works. If you load one of
the portlets on a page and continually hit reload (ie not letting it fully load between
hits), then this error can also be reproduced in this manner (it doesn't occur all the
time, but will happen occasionally).
