2004-08-19 12:47

please, I?m sorry about my english because I?m brazilian.

I create a variable (java.lang.Integer) to COUNT the records in detail of my report having resetType="Page" - calculation="Count" because this report have a subreport and I want disable the print of the grouHeader when don?t have records of detail in the page. I test this report with ten records and in the first page my variable return 10 and in the others return null so I put the follow expression in my groupHeader band (print when Expression) : new Boolean($V{variable} != null)

and after this the report never show the groupHeader !!
