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.ide/src/org/eclipse/birt/report/designer/ui/editors/IDEMultiPageReportEditor.java
if ( getEditorInput( ) != null )
		{
			getFile( getEditorInput( ) ).getWorkspace( )
					.removeResourceChangeListener( resourceListener );
		}
		super.setInput( input );
		if ( getEditorInput( ) != null )
		{
			getFile( getEditorInput( ) ).getWorkspace( )
					.addResourceChangeListener( resourceListener );
		}
	}
	private IFile getFile( IEditorInput editorInput )
	{
		if ( editorInput instanceof FileEditorInput )
		{
			return ( (FileEditorInput) editorInput ).getFile( );
		}
		return null;
	}
	public void partActivated( IWorkbenchPart part )
	{
		super.partActivated(part );
		if ( part != this )
