Hugo Mendoza's andwer guided me to solve the problem. I'm using Jaspersoft Studio. During Crosstab Wizard, when you select the field to put inside the cell, the default "aggregate function" is count. Changing the function during the wizard, rise a Null Pointer Exception so leave "count" as function. Now, edit the Crosstab and use "SUM" function for your measure. If you use "none" as function, the value will be printed correctly in the cell but TOTALS Cells doesn't work. So us SUM for your measure.
