Encountered a strange error in Simple Charts Pie charts. Suddenly the charts stopped working, I only get the layout, chart title etc but no pie (data). Other charts continue to work fine. Started the application from the modeler and found two errors: A warning: Object with the following id couldn't be retrieved: '[MendixIdentifier:: guid=281582350894492 objectType=ProjectManagement.RemunerationSpecification objectTypeHash=25 dataStoreCode=1 objectStoreId=1436]' An error: org.codehaus.jackson.JsonGenerationException: Current context not an ARRAY but OBJECT at org.codehaus.jackson.impl.JsonGeneratorBase._reportError(JsonGeneratorBase.java:375) at org.codehaus.jackson.impl.JsonGeneratorBase.writeEndArray(JsonGeneratorBase.java:152) at dG.a(SourceFile:213) at dG.a(SourceFile:197) at dG.a(SourceFile:135) at dG.a(SourceFile:82) at kx.a(SourceFile:52) at jy.a(SourceFile:300) at jy.a(SourceFile:232) at jy.processRequest(SourceFile:183) at fA.a(SourceFile:75) at com.mendix.core.MxRuntime.processRequest(SourceFile:893) at com.mendix.m2ee.server.handler.RuntimeHandler.handle(RuntimeHandler.java:40) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:113) at org.eclipse.jetty.server.Server.handle(Server.java:334) at org.eclipse.jetty.server.HttpConnection.handleRequest(HttpConnection.java:559) at org.eclipse.jetty.server.HttpConnection$RequestHandler.content(HttpConnection.java:1007) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:747) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:209) at org.eclipse.jetty.server.HttpConnection.handle(HttpConnection.java:406) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:462) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:436) at java.lang.Thread.run(Thread.java:619) Any suggestion?
