Custom datasource in subreport

2004-04-07 13:48

I have "main" report with custom datasource "A". How can I use this custom datasource "A" for some subreports? I need "REPORT_CONNECTION" functionality with custom datasource. Is it possible?

I have been able to use custom datasources in a main and sub report - although I'm not totally happy with the mechanism yet - mostly due to the security requirements of my own application.


What I've done is:

in the subReport tab of the subreport element properties: select "Use datasource expression". The expression is a static method which returns a JRDatasource which the subreport will use. It is like the expression used in your main custom datasource except that you can specify a parameter which will probably be the link between your main an sub reports. My expression is:


where conversationId links the main and sub reports.
