Bug 116706 Bad Class Cast in IDEReportEditor.java
So I'm trying to open a report with BIRT/Eclipse API using the BIRT 2.0 nightly build code (as of 11/16/2005). the file IDEReportEditor.java method private IFile getFile( IEditorInput input ) { return ( (ReportFileEditorInput) input ).getFile( ); } However, input can be ReportEditorInput which is also an IEditorInput (to support reports found outside projects and workspaces) which doesn't even have a getFile() method on it. This causes a deeply nested exception that causes the report desinger to not be able to show a report that might be physically located outside a workspace.
UI/org.eclipse.birt.report.designer.ui/src/org/eclipse/birt/report/designer/ui/actions/BaseInsertMenuAction.java
* 
	 * @see org.eclipse.jface.action.Action#run()
	 */
	public void run( )
	{
		if ( Policy.TRACING_ACTIONS )
		{
			System.out.println( "Insert action >> Run ..." ); 
		}
		CommandStack stack = SessionHandleAdapter.getInstance( )
				.getCommandStack( );
		stack.startTrans( STACK_MSG_INSERT_ELEMENT );
		try
		{
			final Request req = insertElement( );
			if ( req != null )
			{
				stack.commit( );
				selectElement( req.getExtendedData( )
						.get( IRequestConstants.REQUEST_KEY_RESULT ), true );
				return;
			}
		}
		catch ( Exception e )
		{
			ExceptionHandler.handle( e );
		}
		stack.rollback( );
	}
}
