Brian DeHamer updated PLUTO-506:
--------------------------------
Attachment: patch-506.txt
The attached patch to the PreferencesValidatorRegistry class updates the
getPreferencesValidator method to ensure that the PortletPreferencesDD is
non-null before invoking its getPreferencesValidator() method.
> Invoking the store() method of PortletPreferences object results in NPE if no
> preferences declared in portlet.xml

>
> If you have not declared any preferences for a portlet in the deployment
> descriptor (portlet.xml) and then invoke the store() method of the
> PortletPreferences object, a NullPointerException is thrown with the
> following stack trace:
> java.lang.NullPointerException
> at
> org.apache.pluto.internal.PreferencesValidatorRegistry.getPreferencesValidator(PreferencesValidatorRegistry.java:97)
> at
> org.apache.pluto.internal.impl.PortletEntityImpl.getPreferencesValidator(PortletEntityImpl.java:167)
> at
> org.apache.pluto.internal.impl.PortletPreferencesImpl.internalStore(PortletPreferencesImpl.java:298)
> at
> org.apache.pluto.internal.impl.PortletPreferencesImpl.store(PortletPreferencesImpl.java:277)
> . . .
> In the getPreferencesValidator() method of the PreferencesValidatorRegistry
> the PortletPreferencesDD object is retrieved and its
> getPreferencesValidator() method is invoked without first checking to see if
> the PortletPreferencesDD object is null.
> As a workaround you can make sure that you always declare at least one
> preference in your portlet.xml file -- this will ensure that the
> PortletPreferencesDD object is not null.
