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.

{
		if ( outlinePage == null || outlinePage.isDisposed( ) )
		{
			outlinePage = new ReportMultiBookPage( );
		}
		return outlinePage;
	}
	private Object getPalettePage( )
	{
		if ( fPalettePage == null || fPalettePage.isDisposed( ) )
		{
			fPalettePage = new ReportMultiBookPage( );
		}
		return fPalettePage;
	}
	private void updatePaletteView( IFormPage activePageInstance )
	{
		if ( fPalettePage == null )
		{
			return;
		}
		Object palette = activePageInstance.getAdapter( PalettePage.class );
		fPalettePage.setActivePage( (IPageBookViewPage) palette );
	}
	public void pageChange( String id )
	{
		IFormPage page = findPage( id );
		if ( page != null )
		{
			pageChange( page.getIndex( ) );
