Bug 189812 Exceptions occurs when specify two sorting conditions on a crosstab[1102]
Description: Exceptions occurs when specify two sorting conditions on a crosstab[1102] Build number: 2.2.0.v20070530-0630 Steps to reproduce: 1, Open the attached report design 2, Specify the sorting on the crosstab 3, One sorting is : Group Level: Product/PRODUCTLINE Key: CREDITLIMIT_Date/year_Product/PRODUCTLINE Column member valud: year 2003 4, The second sorting is as same as sorting one, but the year value is 2004 Expected result: Support multi sorting on one condition Actual result: Exception occurs Error Logs: org.eclipse.birt.report.service.api.ReportServiceException: Error happened while running the report; nested exception is: java.lang.ArrayIndexOutOfBoundsException: 1 Show Exception Stack Trace Hide Exception Stack Trace Stack Trace: org.eclipse.birt.data.engine.olap.data.impl.aggregation.sort.AggregationSortHelper.createMatchedAggrRow(AggregationSortHelper.java:131) org.eclipse.birt.data.engine.olap.data.impl.aggregation.sort.AggregationSortHelper.populateAggrDiskArray(AggregationSortHelper.java:87) org.eclipse.birt.data.engine.olap.data.impl.aggregation.sort.AggregationSortHelper.sort(AggregationSortHelper.java:53) org.eclipse.birt.data.engine.olap.data.impl.aggregation.sort.AggrSortHelper.sort(AggrSortHelper.java:114) org.eclipse.birt.data.engine.olap.data.api.CubeQueryExecutorHelper.applyAggrSort(CubeQueryExecutorHelper.java:448) org.eclipse.birt.data.engine.olap.data.api.CubeQueryExecutorHelper.execute(CubeQueryExecutorHelper.java:301) org.eclipse.birt.data.engine.olap.query.view.QueryExecutor.populateRs(QueryExecutor.java:129) org.eclipse.birt.data.engine.olap.query.view.QueryExecutor.execute
