Bug 193296 Subquery does not return value for chart
I've tried 2.1.x and 2.2RC but I get always an error. org.eclipse.birt.report.engine.data.dte.DataGenerationEngine doExecuteQuery SEVERE: Data engine operation failed due to an unexpected exception. Error evaluating Javascript expression. Script engine error: TypeError: Cannot read property "ISO_LAND" from null Script source: source, line: 0, text: row._outer["ISO_LAND"] + Result iterator has no current row. It either has not started or has ended. I would like to build a report based on a query that returns a list of countries eg.: report_query=select country_id from ... where sales>100 for each country I'd like to have a line chart with sales vs. budget eg.: sub_query= select month,bud,sales from ... where country = ? If I drag the subquery into the "main" table, connect parameter to row[]. no problem. I get bud vs. sales values for each country. If I place a chart based on sub_query in the "main" table. I get the error shown above. In this case I have to connect the parameter to row._outer[] and for some reason I don't see any values in the chart preview?!?
