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.

			setPartName( provider.getInputPath( getEditorInput( ) )
					.lastSegment( ) );
		}
	}

	public boolean isDirty( )
	{
		fLastDirtyState = computeDirtyState( );
		return fLastDirtyState;
	}
	private boolean computeDirtyState( )
	{
		IFormPage page = getActivePageInstance( );
		if ( page != null && page.isDirty( ) )
			return true;
