Answer 1

This is happening to me when using a JRBeanCollectionDataSource. I know for a fact that all the data is there but the table tool keeps missing the first row.
It looks like the main report executes a ".next()" on the collection or something then the subreport (a.k.a table) keeps on going with the rest of the data
Anyway, I solved it passing $P{REPORT_DATA_SOURCE}.cloneDataSource() as the dataSource expression of the table. Then it looks like the table starts with a brand new datasource and can iterate through all the items, and so, it works.
I don't know what datasource you are using but you have to figure out a way to move the cursor to the beginning of your data before using the subreport.
So, summing up, I did this in my jrxml file:
<dataSourceExpression><![CDATA[$P{REPORT_DATA_SOURCE}.cloneDataSource()]]></dataSourceExpression>
but Only because I am using a JRBeanCollectionDataSource

Answer 2

Exactly the same problem as kawda and exactly the same behavior than user1972796 : multiple tables instead of one, but correct number of rows in one table.
The problem seams to appear in cases where the master report doesn't iterate over anything and the subreport has been put into the Details Band and references the master data source via $P{REPORT_DATA_SOURCE}
The explanation (and solution) seams to be this one: http://community.jaspersoft.com/wiki/why-first-record-missing-my-subreport

Answer 3

Maybe you should use <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>instead <dataSourceExpression><![CDATA[$P{REPORT_DATA_SOURCE}]]></dataSourceExpression>
