> If you have not declared any <user-attribute> elements in the portlet
> deployment descriptor (portlet.xml) and then attempt to retrieve the user
> information Map from the PortletRequest object a NullPointerException is
> thrown:
> java.lang.NullPointerException
> at
> org.apache.pluto.core.DefaultRequestAttributeService.createUserInfoMap(DefaultRequestAttributeService.java:196)
> at
> org.apache.pluto.core.DefaultRequestAttributeService.getAttribute(DefaultRequestAttributeService.java:80)
> at
> org.apache.pluto.internal.impl.PortletRequestImpl.getAttribute(PortletRequestImpl.java:436)
> In the createUserInfoMap() method of the DefaultRequestAttributeService
> class, the getUserAttribute() method of the PortletDD is invoked and the
> returned List is used in a foreach loop -- however, this return value is not
> checked for a null value before it is used in the loop.
> As a workaround you can make sure that you always declare at least one
> <user-attribute> element in your portlet.xml file -- this will ensure that
> the list returned by getUserAttribute() is no null.
