Dear, Since the upgrade from VS2008 to VS2015 and appserver 10.2B to 11.6.3 we get the error: [procedurename] :Input result error: System.NullReferenceException: De objectverwijzing is niet op een exemplaar van een object ingesteld. There might be a mismatch between an input result set and the schema in the proxy. (7228) First we go to the AppServer to ask a dataset with 1 temptable tmp-filter with no records. Getting a datasethandle is not a problem. ws_ParamArray = new ParamArray(1); ws_ParamArray.AddDatasetHandle(0, outDataSet, ParamArrayMode.OUTPUT, ioProDataSetMetaData); wsOpenProcObject.RunProc("NewFilter", ws_ParamArray); Between these sources we filled up tmp-filter with 1 record with filterdata. After that, we put the dataset again to the AppServer to getResults based on the filter. But input a datasethandle gives errors: ws_ParamArray = new ParamArray(1); ws_ParamArray.AddDatasetHandle(0, outDataSet, ParamArrayMode.INPUT, ioProDataSetMetaData); wsOpenProcObject.RunProc("SetFilter", ws_ParamArray); ioProDataSetMetaData is initialised like: ioProDataSetMetaData = new ProDataSetMetaData("", null); What could be the reason of this error? Thanks in advance.
