Jacques Le Roux commented on OFBIZ-4289: ---------------------------------------- Jacopo, I reviewed and it's ok with me, much simpler no longer need to muck around with apps-distributable in LoginWorker. Of course I briefly tested in both cases and it works. Not surprising, since we have no longer these 4 non serialised variables in session. One more thing I'd do though: replace FastMap by HashMap in UtilHttp.getParameterMap(). Because this is still used in at least LoginWorker.checkLogin() to put _PREVIOUS_PARAM_MAP_FORM_ insession, see this snippet {code} Map<String, Object> formParams = UtilHttp.getParameterMap(request, urlParams.keySet(), false); if (UtilValidate.isNotEmpty(formParams)) { session.setAttribute("_PREVIOUS_PARAM_MAP_FORM_", formParams); } {code} And morevoer it could be used in other cases by not aware developers. My patch above can be used, not sure why you did not, so I don't commit... > Login out on a cluster handled by DeltaManager causes a NPE > ----------------------------------------------------------- > > Key: OFBIZ-4289 > URL: https://issues.apache.org/jira/browse/OFBIZ-4289 > Project: OFBiz > Issue Type: Bug > Components: framework > Affects Versions: Release Branch 4.0, Release Branch 09.04, Release Branch > 10.04, Release Branch 11.04, SVN trunk > Environment: Ubuntu > Reporter: Jacques Le Roux > Assignee: Jacques Le Roux > Priority: Critical > Labels: cluster, logout > Fix For: Release Branch 10.04, Release Branch 11.04, SVN trunk > > Attachments: OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, OFBIZ-4289_Login_out_on_a > cluster_handled_by_DeltaManager_causes_a_NPE.patch, changeset_2510.diff, > ofbiz.log > > > It works locally but not on clusters.
