IBM BS029ML - WebSphere Portal Server Self Help Manual page 206

Perhaps the single most valuable tool on the support page is the Search box. See
Figure A-16.
Figure A-16 The WebSphere Portal product support page's search box
This is the primary input mechanism for finding the answers you need to the questions you
might have. For example, if you are receiving a particular message code during some
operations of your portal, copy that code into the search box and view the results. This is our
interface to numerous datasources across the IBM sites and is the easiest way to use the
page to meet your needs. Search results are provided with an indication of relevancy and
even by date.
For this example, we have deployed our portal and are using custom themes and skins
throughout. After assigning a new theme to the portal's Administration pages, the
administrator has been unable to "assign access to a portlet" when using the Manage Portlets
administrative portlet. Instead, the administrator receives the dreaded "This portlet is not
available" message in its place.
Checking the wps_<date-time>.log file, the administrator sees this entry:
2007.08.16 19:03:22.101 E com.ibm.wps.engine.tags.PortletRenderTag doStartTag
EJPEJ0066E: The portlet could not be rendered. - StackTrace follows...
2007.08.16 19:03:22.101 E com.ibm.wps.engine.tags.PortletRenderTag
doStartTag
javax.portlet.PortletException
. . . .
Caused by: java.lang.NullPointerException
at
com.ibm.wps.portlets.permissions.PermissionsPortlet.doView(PermissionsPortlet.java
:192)...
The administrator also found that by restoring the default "out-of-the-box" theme for the admin
pages, this problem did not occur.
