Passing Drill Down Parameters to another report not being read by Datset

BlackaJ

Hi,

I am new to Birt and am experiencing an issue with drill thorugh charting.

I have a Dataset that reads data from an Oracle 11 DB.

The report is a line chart that has Start and End Date Parameters and this produces a chart as expected
- I am using the beforeOpen event on the Dataset to filter using the parameters.

I require to click on the Chart and the Start and End Date Parameters be passed to the second report and
Filter on these passed parameter values.

The issue that I am encountering is that the passed parameter values do not appear to be read by the beforeOpen event on the Dataset of the Second Report.

If I run the second report in its own and enter parameters, it works as expected.

To ensure that the values are being passed through, I have placed the parameter objects to the report and the passed data is appearing - hence is being populated.

Any help would be appreciated

If you can create a master and detail report with the sample database and attach them in here, so I can see exactly what you're doing and test on the reports, that'd be great! Thanks!
