Each time I want to delete a folder (on Alfresco 1.4.0 CE), I get an error :
ERROR [org.alfresco.web.ui.common.Utils] Unable to delete Space due to system error: java.lang.NullPointerException at org.alfresco.web.bean.BrowseBean.removeSpaceFromBreadcrumb(BrowseBean.java:1380) at org.alfresco.web.bean.spaces.DeleteSpaceDialog.doPostCommitProcessing(DeleteSpaceDialog.java:152) at org.alfresco.web.bean.dialog.BaseDialogBean.finish(BaseDialogBean.java:96) at org.alfresco.web.bean.dialog.DialogManager.finish(DialogManager.java:311) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.myfaces.el.MethodBindingImpl.invoke(MethodBindingImpl.java:129) at org.apache.myfaces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:63) at javax.faces.component.UICommand.broadcast(UICommand.java:106) at javax.faces.component.UIViewRoot._broadcastForPhase(UIViewRoot.java:90) at javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:164) at org.apache.myfaces.lifecycle.LifecycleImpl.invokeApplication(LifecycleImpl.java:316) at org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:86) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:105) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.alfresco.web.app.servlet.AuthenticationFilter.doFilter(AuthenticationFilter.java:73) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)
After that I need to click on the Cancel button. And I can see that the folder have disapear !!
So, I think the deletion work. But how I can remove this error message ?
I have removed the thumbnails extension and everything seems to behave better now. Is there a version of thumbnails that works well with 1.4 war deployment ???
Just saw this post. Hopefully you saw that a 1.4.1 compatible version, along with several other changes, of the thumbnails extenion was released last month.
