Bug 193259 Enhance about the process of java script and event handler.[08]
Description: Enhance about the conflict of java script and event handler. I have a case, I design a report with script data source and script dataset. Previously I wrote java script for dataset in script view and it works. Then I decided to use event handler to process script dataset, I wrote a java class to extends ScriptedDataSetEventAdapter and overwrite open and fetch methods. As I want to keep the script in script view, I just comment them by /**/. Run the report will throw Exception. I found it's caused by comments in script view. If I deleted them, the report works. I attached the report and java class.
engine/org.eclipse.birt.report.engine/src/org/eclipse/birt/report/engine/script/internal/ScriptDataSetScriptExecutor.java
implements IScriptDataSetEventHandler
{
	private static final String OPEN = "OPEN";
	private static final String CLOSE = "CLOSE";
	private static final String FETCH = "FETCH";
	private static final String DESCRIBE = "DESCRIBE";
	private IScriptedDataSetEventHandler scriptedEventHandler;
	public ScriptDataSetScriptExecutor( ScriptDataSetHandle dataSetHandle,
			ExecutionContext context )
	{
		super( dataSetHandle, context );
	}
	protected void initEventHandler( String className )
	{
		super.initEventHandler( className );
		if ( eventHandler != null )
		{
			try
			{
				scriptedEventHandler = ( IScriptedDataSetEventHandler ) eventHandler;
			} catch ( ClassCastException e )
			{
				addClassCastException( context, e, className,
						IScriptedDataSetEventHandler.class );
			}
		}
