first groupname is empty

Hi have an xml file like this (this is delivered by an external partner):

 

Code:

<report>
  <row>
    <date>23.01.2006</date>
    <valueA>2345</valueA>
  </row>
  <row>
    <date>21.05.2007</date>
    <valueA>12345</valueA>
  </row>
  <row>
    <date>23.05.2007</date>
    <valueA>22345</valueA>
  </row>
<report>

next thing is that i build a report about values and the date. then i wanted to group by month and year.

so i build a varible with the following expression (monthYearGroup):

Code:

[code]new Integer(new String($F{date}.substring(6,10)+$F{date}.substring(3,5)))

so i get the two groups:

200601 and 200705.

The pdf shows 2 groups but the groupheader (monthYearGroup) shows "null" at the first and then it shows "200601" - "200705" is never shown.

Why does jpR show "null" at the first group?

Did i miss something?

If you display the variable in the group header, make sure you set evaluationTime="Group" and evaluationGroup="MyGroupName".

 

HTH,
