groupExpression evaluating two expressions

2002-09-20 14:47

is it possible to do something like the following?

 

<groupExpression>($F{id} && new Boolean($F{resultsLimit}.intValue() > $V{limitCnt}.intValue()))</groupExpression>

 

I need it to group id's but also limit the number of times the group is written.

 

Thanks in advance.

 

bt..

parameter based groupExpression

Hi,

I'm trying to determine the group expression at run-time using a scriptlet method based on an input parameter.

 

<groupExpression>

 

((com.dp.scriptlets.DateScriptlet)$P{REPORT_SCRIPTLET}).determineGrouping($P{GroupBy})

 

</groupExpression>

 

the determineGrouping method returns a java.lang.String "$F{LotNumber}", so that grouping can be done based on the lot number field. But this doesnt seem to work. If I replace the scriptlet call by $F{LotNumber} then the grouping works fine.

 

Hope someone can help.

 

Thanks..
