Scripted datasource not work correctly!

[nguyendu0102]

     Hi all,

  I don't know how to explain about my problem when i use birt report with scripted data source.
 In a project it ok. but when i creat another project sometime it work, sometime throw exception
The following items have errors:


ReportDesign (id = 1):
+ There are errors evaluating script "if(count < c.size()-1) {
 row["id"] = c.get(count).getId();
 row["name"] = c.get(count).getName();
 row["birth"] = c.get(count).getBirth();
 return true;
}
return false;":{1}.
Error.ScriptEvaluationError ( 1 time(s) )
