Hi there, I have a report which contains a java.util.Collection as an input parameter. I then use this in the SQL Query using the $X{IN, field, parameter} operation. On JasperServer, I have set up a Multi-Select query input control which displays a list of possible values. Behind this there is a query to retrieve the info from the database. I now want to use this report as a drill-down from another report, i.e. embed a hyperlink in the parent report. I would like in this instance for the multi-select input to be populated with ALL the values in the database. I was thinking there would be some way of either setting up a subdataset in the parent or the child, entering the query in here to retrieve the list of values, and either sending it as the parameter in the hyperlink in the parent report, or using it as the default value in the child report. What is the best way to go about doing this? Thanks Neal
