Dear all, I am currently running the **b2019021702** build. The following error occurs when I save in the designer: > 12:33:01.536 [AWT-EventQueue-0] WARN Perspective.SessionProps - Unable to obtain session props for save. > java.lang.IllegalArgumentException: Resource cannot be overridden. > at com.inductiveautomation.ignition.designer.project.ResourceTreeNode.update(ResourceTreeNode.java:90) > at com.inductiveautomation.ignition.designer.project.DesignerProjectTreeImpl.createResourceInternal(DesignerProjectTreeImpl.java:197) > at com.inductiveautomation.ignition.designer.project.DesignerProjectTreeImpl.createResource(DesignerProjectTreeImpl.java:187) > at com.inductiveautomation.ignition.designer.project.DesignableProject.createOrModify(DesignableProject.java:168) > at com.inductiveautomation.perspective.designer.workspace.pageconfig.SessionPropsAdapter.commit(SessionPropsAdapter.java:98) > at com.inductiveautomation.perspective.designer.workspace.pageconfig.WorkspaceRootConfig.commit(WorkspaceRootConfig.java:28) > at com.inductiveautomation.perspective.designer.workspace.ViewWorkspace.notifyProjectSaveStart(ViewWorkspace.java:243) > at com.inductiveautomation.perspective.designer.DesignerHook.notifyProjectSaveStart(DesignerHook.java:393) > at com.inductiveautomation.ignition.designer.IgnitionDesigner.commitAll(IgnitionDesigner.java:1413) > at com.inductiveautomation.ignition.designer.IgnitionDesigner.handleSave(IgnitionDesigner.java:1204) > at com.inductiveautomation.ignition.designer.IgnitionDesigner.access$2600(IgnitionDesigner.java:188) > at com.inductiveautomation.ignition.designer.IgnitionDesigner$Handler.handleSaveAction(IgnitionDesigner.java:2535) > at com.inductiveautomation.ignition.designer.IgnitionDesigner$Handler.access$1100(IgnitionDesigner.java:1964) > at com.inductiveautomation.ignition.designer.IgnitionDesigner$Handler$5.actionPerformed(IgnitionDesigner.java:2146) > at java.desktop/javax.swing.AbstractButton.fireActionPerformed(Unknown Source) > at java.desktop/javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) > at java.desktop/javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) > at java.desktop/javax.swing.DefaultButtonModel.setPressed(Unknown Source) > at java.desktop/javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) > at com.jidesoft.plaf.basic.BasicJideButtonListener.mouseReleased(Unknown Source) > at java.desktop/java.awt.AWTEventMulticaster.mouseReleased(Unknown Source) > at java.desktop/java.awt.Component.processMouseEvent(Unknown Source) > at java.desktop/javax.swing.JComponent.processMouseEvent(Unknown Source) > at java.desktop/java.awt.Component.processEvent(Unknown Source) > at java.desktop/java.awt.Container.processEvent(Unknown Source) > at java.desktop/java.awt.Component.dispatchEventImpl(Unknown Source) > at java.desktop/java.awt.Container.dispatchEventImpl(Unknown Source) > at java.desktop/java.awt.Component.dispatchEvent(Unknown Source) > at java.desktop/java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) > at java.desktop/java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) > at java.desktop/java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) > at java.desktop/java.awt.Container.dispatchEventImpl(Unknown Source) > at java.desktop/java.awt.Window.dispatchEventImpl(Unknown Source) > at java.desktop/java.awt.Component.dispatchEvent(Unknown Source) > at java.desktop/java.awt.EventQueue.dispatchEventImpl(Unknown Source) > at java.desktop/java.awt.EventQueue$4.run(Unknown Source) > at java.desktop/java.awt.EventQueue$4.run(Unknown Source) > at java.base/java.security.AccessController.doPrivileged(Native Method) > at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source) > at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source) > at java.desktop/java.awt.EventQueue$5.run(Unknown Source) > at java.desktop/java.awt.EventQueue$5.run(Unknown Source) > at java.base/java.security.AccessController.doPrivileged(Native Method) > at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source) > at java.desktop/java.awt.EventQueue.dispatchEvent(Unknown Source) > at java.desktop/java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) > at java.desktop/java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) > at java.desktop/java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) > at java.desktop/java.awt.EventDispatchThread.pumpEvents(Unknown Source) > at java.desktop/java.awt.EventDispatchThread.pumpEvents(Unknown Source) > at java.desktop/java.awt.EventDispatchThread.run(Unknown Source) Thank you. ---

> [@andrea.morando](#): > > when the bug will be fixed inside the nightly build? Read the linked post - the bug has already been fixed for anyone going forward. If you don't have a backup you can restore that's older than either of those two affected versions, you can try running the script @Kevin.Herron posted in the linked thread to 'fix' your resources. ---

Ok, thanks. The “overridable” properties are fixed.
