not getting data when using scripted dataset in rcp designer

This is my Java code line which I am using to pass the data into a birt task:

activityReportTask.addScriptableJavaObject("activitybean", activityBeanList);

Now I am using rcp designer to create the *.rptdesign file for this data, there I'm using the following script in open and in fetch:

for open:

activities = activitybean;
totalrows = activities.size();
currentrow = 0;
cumulativeDistance = 0;

for fetch:

if (currentrow >= totalrows){
 return false;
}

bean = activities.get(currentrow);
cumulativeDistance = cumulativeDistance +  bean.getDistance(); 
dataSetRow["time"] = bean.getTime();
dataSetRow["speed"] = bean.getSpeed();
dataSetRow["latitude"] = bean.getLatitude();
dataSetRow["longitude"] = bean.getLongitude();
dataSetRow["distance"] = bean.getDistance();
dataSetRow["cumulativeDistance"] = cumulativeDistance;
dataSetRow["place"] = bean.getPlace();
currentrow = currentrow+1;
return true;

but when I try to preview the report, I'm getting this error:

The following items have errors:

ReportDesign (id = 1): 
+ There are errors evaluating script "activities = activitybean;
totalrows = activities.size();
currentrow = 0;

{1}.

Can anyone help figure out the cause and resolution for these errors?

I haven't "played" with java objects in birt but when I see it correctly the reference to the activitybean does not work. Since addScriptableJavaObject is deprecated try to add the list via:

HashMap hm = config.getAppContext(); hm.put( "activitybean", activityBeanList );

And then access it in the report via

appContext = reportContext.getAppContext();
activities = appContext.get("activitybean");

If this does not work, there is a great tutorial on using java object in birt from Lars Vogel: EclipseBirt

Good luck!
