Hi guys, So we upgraded our app from version 4.4.3.1 to version 5.13.0 and sorted out every single issue but for one issue. Our Simple chart widget which works perfectly in version 4.4.3.1 that gets data from a single entity does not work in version 5.13.0. We have updated the widget and tried numerous things but no luck. Probelm in version 5.13.0 the chart simple does not render at all, blank screen. In version 4.4.1.3 its works perfectly. using Highcharts. Please help :) error in the console below: java.lang.IllegalArgumentException: Meta object name should not be null or empty at com.mendix.core.objectmanagement.SchemeManagerImpl.getMetaObject(SchemeManagerImpl.java:1520) at com.mendix.core.component.InternalCore.getMetaObject(InternalCore.java:2023) at com.mendix.webui.actions.client.XPathRetriever.setReferences(XPathRetriever.scala:144) at com.mendix.webui.actions.client.XPathRetriever.retrieveWithoutSchema(XPathRetriever.scala:110) at com.mendix.webui.actions.client.RetrieveByXPathAction.execute(RetrieveByXPathAction.scala:39) at com.mendix.webui.requesthandling.ClientRequestHandler$$anonfun$handleRequest$1.apply$mcV$sp(ClientRequestHandler.scala:300) at com.mendix.webui.requesthandling.ClientRequestHandler$$anonfun$handleRequest$1.apply(ClientRequestHandler.scala:293) at com.mendix.webui.requesthandling.ClientRequestHandler$$anonfun$handleRequest$1.apply(ClientRequestHandler.scala:293) at com.mendix.core.session.Worker$$anonfun$receive$3$$anonfun$2$$anon$1.execute(ActionDispatching.scala:151) at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:37) at com.mendix.core.session.Worker$$anonfun$receive$3$$anonfun$2.apply(ActionDispatching.scala:153) at scala.util.Try$.apply(Try.scala:191) at com.mendix.core.session.Worker$$anonfun$receive$3.applyOrElse(ActionDispatching.scala:147) at akka.actor.Actor$class.aroundReceive(Actor.scala:465) at com.mendix.core.session.Worker.aroundReceive(ActionDispatching.scala:140) at akka.actor.ActorCell.receiveMessage(ActorCell.scala:516) at akka.actor.ActorCell.invoke(ActorCell.scala:487) at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:238) at akka.dispatch.Mailbox.run(Mailbox.scala:220) at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(AbstractDispatcher.scala:393) at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) at scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) at scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) at scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107)
