Bug 201205 Exception occurs in dataset preview when IN filter contains a blank value[0802]
Description: Exception occurs in dataset preview when IN filter contains a blank value[0802] Build number: 2.2.1.v20070827-0630 Steps to reproduce: 1, New a sampleDB customer dataset 2, New a filter and operator is IN 3, Specify a blank value and add 4, Preview in dataset Expected result: The preview should be successful and no exception Actual result: Exception occurs Error log: org.eclipse.birt.report.designer.core.runtime.GUIException: Caused by java.lang.reflect.InvocationTargetException. at org.eclipse.birt.report.designer.core.runtime.GUIException.createGUIException(GUIException.java:76) at org.eclipse.birt.report.designer.internal.ui.util.ExceptionHandler.handle(ExceptionHandler.java:169) at org.eclipse.birt.report.designer.internal.ui.util.ExceptionHandler.handle(ExceptionHandler.java:150) at org.eclipse.birt.report.designer.internal.ui.util.ExceptionHandler.handle(ExceptionHandler.java:89) at org.eclipse.birt.report.designer.data.ui.dataset.ResultSetPreviewPage.updateResultsProcess(ResultSetPreviewPage.java:515) at org.eclipse.birt.report.designer.data.ui.dataset.ResultSetPreviewPage.runUpdateResults(ResultSetPreviewPage.java:274) at org.eclipse.birt.report.designer.data.ui.dataset.ResultSetPreviewPage.access$1(ResultSetPreviewPage.java:244) at org.eclipse.birt.report.designer.data.ui.dataset.ResultSetPreviewPage$4.runInUIThread(ResultSetPreviewPage.java:237)
