Bug 208501 AdapterException occurs when preview a crosstab with a integer type static level[1102]
Description: AdapterException occurs when preview a crosstab with a integer type static level[1102] Build number: 2.3.0.v20071102-0630 Steps to reproduce: 1, New a cube from CUSTOMERS 2, New a static level has two Member 1 and 2. 1's expression is dataSetRow["CUSTOMERNUMBER"]>250. 2's expression is dataSetRow["CUSTOMERNUMBER"]<250 3, New a crosstab using the cube 4, Preview Expected result: If we can convert Memeber 1 and 2 to integer type, the preview should be ok. If we do not do this convert we should throws out a proper exception. Actual result: org.eclipse.birt.report.data.adapter.api.AdapterException: java.lang.String OCCURS Error log: java.lang.String ( 2 time(s) ) detail : org.eclipse.birt.report.data.adapter.api.AdapterException: java.lang.String at org.eclipse.birt.report.data.adapter.impl.DataRequestSessionImpl.prepare(DataRequestSessionImpl.java:479) at org.eclipse.birt.report.engine.data.dte.DteDataEngine.doPrepareQuery(DteDataEngine.java:100) at org.eclipse.birt.report.engine.data.dte.AbstractDataEngine.prepare(AbstractDataEngine.java:138) at org.eclipse.birt.report.engine.executor.ReportExecutor.execute(ReportExecutor.java:94) at org.eclipse.birt.report.engine.internal.executor.wrap.WrappedReportExecutor.execute(WrappedReportExecutor.java:59) at org.eclipse.birt.report.engine.internal.executor.dup.SuppressDuplciateReportExecutor.execute(SuppressDuplciateReportExecutor.java:51) at org.eclipse.birt.report.engine.internal.executor.wrap.WrappedReportExecutor.execute(WrappedReportExecutor.java:59) at org.eclipse.birt.report.engine.api.impl.RunAndRenderTask.doRun(RunAndRenderTask.java:138)
