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 ( stack != null )

	public void init( IWorkbenchWindow window )
	{
		WrapperCommandStack stack = (WrapperCommandStack) getCommandStack( );
		if ( stack != null )
		{
			designHandle = getDesignHandle( );
			stack.setActivityStack( getDesignHandle( ).getCommandStack( ) );
			stack.addCommandStackListener( getCommandStackListener( ) );
		}
	}
	private void resetCommandListener( )
	{
		WrapperCommandStack stack = (WrapperCommandStack) getCommandStack( );
		if ( stack != null && getDesignHandle( ) != designHandle )
		{
			designHandle = getDesignHandle( );
			stack.removeCommandStackListener( getCommandStackListener( ) );
			stack.setActivityStack( getDesignHandle( ).getCommandStack( ) );
			stack.addCommandStackListener( getCommandStackListener( ) );
