After updating to 5.15 we are receiving this error when importing a (rather simple) excel file. Are there any solutions for this? I have updated the importer to the last version com.mendix.core.CoreException: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreException: com.mendix.core.CoreException: Document could not be imported, because: Error while processing the MetaInfoObjects: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V | VERSION: Mx5_20150203 at com.mendix.core.component.InternalCore.execute(InternalCore.java:236) Caused by: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreException: com.mendix.core.CoreException: Document could not be imported, because: Error while processing the MetaInfoObjects: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V | VERSION: Mx5_20150203 at com.mendix.core.actionmanagement.ActionManager.executeSync(ActionManager.java:217) Caused by: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreException: com.mendix.core.CoreException: Document could not be imported, because: Error while processing the MetaInfoObjects: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V | VERSION: Mx5_20150203 at com.mendix.util.classloading.Runner.doRunUsingClassLoaderOf(Runner.java:43) Caused by: com.mendix.core.CoreException: com.mendix.core.CoreException: Document could not be imported, because: Error while processing the MetaInfoObjects: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V | VERSION: Mx5_20150203 at excelimporter.reader.ExcelImporter.startImport(ExcelImporter.java:133) Caused by: com.mendix.core.CoreException: Document could not be imported, because: Error while processing the MetaInfoObjects: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V | VERSION: Mx5_20150203 at excelimporter.reader.readers.ExcelReader.importData(ExcelReader.java:450) Caused by: replication.ReplicationSettings$MendixReplicationException: Error while processing the MetaInfoObjects: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V | VERSION: Mx5_20150203 at replication.MetaInfo.finished(MetaInfo.java:687) Caused by: replication.ReplicationSettings$MendixReplicationException: Error while processing the MetaInfoObjects: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V | VERSION: Mx5_20150203 at replication.MetaInfo.startProcessingObjects(MetaInfo.java:635) Caused by: replication.ReplicationSettings$MendixReplicationException: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V at replication.MetaInfo.validateRunningThreads(MetaInfo.java:660) Caused by: java.lang.NoSuchMethodError: com.mendix.systemwideinterfaces.connectionbus.data.IDataTable.close()V at replication.MetaInfoProcessor.retrieveMxObjectsByMetaInfoObject(MetaInfoProcessor.java:751) at replication.MetaInfoProcessor.storeChangedObjects(MetaInfoProcessor.java:127) at replication.MetaInfoProcessor.run(MetaInfoProcessor.java:75)
