Hi everyone, I’m working on a legacy Vision project running on Ignition 8.0.10. The application runtime/client works correctly since 2020 and the affected window functions normally during runtime, but the Designer cannot open the window anymore. The problematic window is my MainPage. When opening the window from the Designer, the following errors appear in the console: > text id="m1w2xp" 11:31:08.123 [AWT-EventQueue-0] ERROR com.inductiveautomation.ignition.client.util.gui.ErrorUtil - null com.inductiveautomation.ignition.common.xmlserialization.SerializationException: Error invoking [HashMap]{PMIButton: Button=[com.inductiveautomation.factorypmi.application.binding.action.ActionAdapter@33d74660]}.put(PMIButton: Button) at com.inductiveautomation.ignition.common.xmlserialization.deserialization.handlers.ObjectDeserializationHandler.endSubElement(ObjectDeserializationHandler.java:82) at com.inductiveautomation.ignition.common.xmlserialization.deserialization.XMLDeserializer$ParseContext.onElementEnd(XMLDeserializer.java:906) at com.inductiveautomation.ignition.common.xmlserialization.deserialization.XMLParser.endElement(XMLParser.java:96) at java.xml/com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanEndElement(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(Unknown Source) at java.xml/com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at com.inductiveautomation.ignition.common.xmlserialization.deserialization.XMLDeserializer.deserializeXML(XMLDeserializer.java:384) at com.inductiveautomation.ignition.common.xmlserialization.deserialization.XMLDeserializer.deserialize(XMLDeserializer.java:261) at com.inductiveautomation.factorypmi.application.model.WindowCache.\_deserializeWindow(WindowCache.java:374) at com.inductiveautomation.factorypmi.application.model.WindowCache.\_loadWindow(WindowCache.java:317) at com.inductiveautomation.factorypmi.application.model.WindowCache.openWindow(WindowCache.java:291) at com.inductiveautomation.factorypmi.designer.workspace.WindowWorkspace$DesigntimeWindowOpener.openWindow(WindowWorkspace.java:3532) at com.inductiveautomation.factorypmi.designer.workspace.WindowWorkspace.openWindow(WindowWorkspace.java:1296) at com.inductiveautomation.factorypmi.designer.model.navtree.WindowNode.open(WindowNode.java:270) at com.inductiveautomation.ignition.designer.navtree.model.AbstractResourceNavTreeNode.onDoubleClick(AbstractResourceNavTreeNode.java:295) at com.inductiveautomation.ignition.designer.navtree.NavTreePanel$MouseListener.lambda$mousePressed$0(NavTreePanel.java:675) at java.desktop/java.awt.event.InvocationEvent.dispatch(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.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) Caused by: java.lang.IllegalArgumentException: null at java.base/jdk.internal.reflect.GeneratedMethodAccessor17.invoke(Unknown Source) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.base/java.lang.reflect.Method.invoke(Unknown Source) at com.inductiveautomation.ignition.common.xmlserialization.deserialization.handlers.ObjectDeserializationHandler.endSubElement(ObjectDeserializationHandler.java:69) ... 35 common frames omitted Invalid Action Adapter found on Button 1.

At this point I would appreciate advice on the safest way to proceed in order to: 1. restore the ability to open the window in the Designer 2. recover editing capabilities for the page 3. avoid rebuilding the entire window manually if possible Has anyone encountered a similar issue on older 8.0.x Vision projects? Any suggestions or recovery strategies would be greatly appreciated. ---

Yes Sorry, I didn't know it was already opened. Thank you
