Bug 122068 [Smoke][Regression]Exception thrown out when preview Chart
Reported: 2005-12-25 22:31:45 | Status: closed fixed

New a report, create a regular chart and preview. Though the chart image is generated, a ClassCastException is thrown out. The handle here actually is an ExtendedItemHandle, not an ImageHandle. ------------------------------------------------------------------------ There are errors on the report page: - There are error(s) in Chart : 580 Error0 : Error.UnhandledScriptError ( 1 time(s) ) detail : org.eclipse.birt.report.engine.api.EngineException: Unhandled exception when executing script at
