Build Identifier: Birt 2.6.1 GA

This issue is similar to https://bugs.eclipse.org/bugs/show_bug.cgi?id=335732. When we generate a report document using API and view in the Birt viewer for reports with drill-downs it throws the following exception,

Caused by: org.eclipse.birt.report.engine.api.EngineException: Error happened while running the report.

Attached is a sample report. More discussed in the forum -

Reproducible: Always

Steps to Reproduce:
1. Create a report with drill-downs (see sample master.rptdesign)
2. Create a document using API,
  task = this.birtEngine.createRunTask(rptDesign); 
  task.run(documentFile.getAbsolutePath()); 
3. Open the document URL using Birt Viewer - you'll see the exception on the screen
