By: Alexandre Gomes - alegomes RE: JasperFillManager.fillReport NullpointerE 2006-01-26 11:06 JasperReports 0.6.4, java version 1.5.0_06 By: Lucian Chirita - lucianc RE: JasperFillManager.fillReport NullpointerE 2006-01-27 00:13 Are you using Hashtable for the parameters map? If so, switch to HashMap because the code assumes that the map supports null values. HTH, Lucian By: Alexandre Gomes - alegomes RE: JasperFillManager.fillReport NullpointerE 2006-01-27 01:23 BINGO! thanks a lotPost edited by: tcloonan, at: 2006/08/26 09:32 Link to comment Share on other sites More sharing options...
