I guess if the user wants to generate multiple view files it won't help, but the initial issue is fixed.

BTW is there a way to generate multiple view files with the generator right now?

You can do it, just repeat something like the following code:

CodeIgniter4/system/Commands/Generators/CellGenerator.php

Lines 88 to 101 in 2534fdc

	$this->templatePath = config(Generators::class)->views[$this->name]['view'];
	$this->template = 'cell_view.tpl.php';
	$this->classNameLang = 'CLI.generator.viewName.cell';
	$className = $this->qualifyClassName();
	$viewName = decamelize(class_basename($className));
	$viewName = preg_replace(
	'/([a-z][a-z0-9_\/\\\\]+)(_cell)$/i',
	'$1',
	$viewName
	) ?? $viewName;
	$namespace = substr($className, 0, strrpos($className, '\\') + 1);
	$this->generateView($namespace . $viewName, $params);
