Bug 155496 Due to inactivity, a group report gives NULL Pointer Exception on selection of TOC and Export CSV option
Steps to reproduce this issue:- 1. Access any Group report that lists groups in TOC 2. For some time do not do any activity on report page (say 15 mins.) 3. Now click on Toggle Table Contents Link 4. The pop window gets opened with following error message java.lang.NullPointerException org.apache.axis.AxisFault.makeFault(AxisFault.java:101) org.eclipse.birt.report.soapengine.processor.AbstractBaseComponentProcessor.process(Unknown Source) org.eclipse.birt.report.soapengine.endpoint.BirtSoapBindingImpl.getUpdatedObjects(Unknown Source) sun.reflect.GeneratedMethodAccessor80.invoke(Unknown Source) When page remains idle for some time the same error gets displayed on selection of Export CSV option. Note:- This issue occurs for the reports that are run using '__overwrite' option. Any help on this is highly appreciated.
