Error description
When a user tries to delete more than one private page consecutively the second delete action (and all following) fail. This is due to a NullPointerException within the Portal's ContentModel that is caused through a wrong initialization of the topology after an invalidation event. Relevant stack trace is: java.lang.NullPointerException at java.util.ArrayList.<init>(ArrayList.java:132) at com.ibm.wps.model.content.impl.SmartTopologyValidator.deleted(Sm rtTopologyValidator.java:422) at com.ibm.wps.model.content.impl.TopologyInvalidatorTask.doItYours lf(TopologyInvalidatorTask.java:118) at com.ibm.wps.model.content.impl.ConcurrentTaskSynchronizer.synchr nizeTask(ConcurrentTaskSynchronizer.java:100) at com.ibm.wps.model.content.impl.SmartTopologyValidator.makeValid( martTopologyValidator.java:209) at com.ibm.wps.model.content.impl.ContentModelImpl.makeValid(Conten ModelImpl.java:1070) at com.ibm.wps.model.content.impl.ContentModelImpl.readBegin(Conten ModelImpl.java:2186) at com.ibm.wps.model.content.impl.ThreadsafeContentModelImpl.readBe in(ThreadsafeContentModelImpl.java:91) at com.ibm.wps.model.content.impl.ContentModelImpl.findByID(Content odelImpl.java:2111) at com.ibm.wps.command.composition.AbstractModelCommand.loadContent ode(AbstractModelCommand.java:284) at com.ibm.wps.command.composition.AbstractCompositionCommand.execu e(AbstractCompositionCommand.java:102) at com.ibm.wps.command.composition.DeleteCompositionCommand.execute DeleteCompositionCommand.java:143) at com.ibm.wps.command.DynamicCommandImpl.execute(DynamicCommandImp .java:157) at com.ibm.wps.engine.commands.DeletePage.execute(DeletePage.java:9 ) at com.ibm.wps.engine.commands.DeletePage.execute(DeletePage.java:5 ) at com.ibm.wps.state.accessors.action.manager.ActionManagerImpl.int rnalExecuteAction(ActionManagerImpl.java:397) at com.ibm.wps.state.accessors.action.manager.ActionManagerImpl.pro essValidAction(ActionManagerImpl.java:355) at com.ibm.wps.state.accessors.action.manager.ActionManagerImpl.int rnalExecuteAction(ActionManagerImpl.java:288) at com.ibm.wps.state.accessors.action.manager.ActionManagerImpl.exe uteActions(ActionManagerImpl.java:175)
