[jira] Created: (PLUTO-506) Invoking the store() method of
PortletPreferences object results in NPE if no preferences declared in
portlet.xml
Invoking the store() method of PortletPreferences object results in NPE if no preferences declared in portlet.xml
-----------------------------------------------------------------------------------------------------------------
Key: PLUTO-506
URL: https://issues.apache.org/jira/browse/PLUTO-506
Project: Pluto
Issue Type: Bug
Components: portlet container
Affects Versions: 2.0.0, 2.0-refactoring
Environment: JDK 1.5.0_16, Tomcat 5.5.27
Reporter: Brian DeHamer
Fix For: 2.0.0, 2.0-refactoring
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.

The attached patch to the PreferencesValidatorRegistry class updates the getPreferencesValidator method to ensure that the PortletPreferencesDD is non-null before invoking its getPreferencesValidator() method.
