Scriptlet "finalize" events for Group

2004-03-29 15:25

The scriptlet provides "Init" events for report/page/group etc

 

What about "finalization" events.

 

I'm trying to create a chart to display the data from each group. In the beforeDetailEval event I'm collecting the data into the series. Once the group is finished I need to add that series to the chart and render the chart into an image, but there is no xxxGroupFinalize() methods.

 

 

Alternatives:

1. Can I see that the group has 'ruptured' in the afterDetailEval() method

2. Can I call a scriptlet method like renderChart() from a field in the report, and place that field in a group footer. Does anyone have an example of this. (The docs say you can, but I couldn't get it to work)

3. <your brilliant suggestion here>

 

Thanks for any help

Paul

OK so I got idea #2 working.

 

I created an image field and set the image evaluation to: ((MyScriptlet)$P{REPORT_SCRIPTLET}).getChartImage().

 

By placing the the image field in the groupfooter band, getChartImage() was called at the end of a group which achieved the desired result.
