TYPO3 Core

Have you looked to the file?

    protected function getWidgetUri() {
        $uriBuilder = $this->controllerContext->getUriBuilder();
        $argumentPrefix = $this->controllerContext->getRequest()->getArgumentPrefix();
        $arguments = $this->hasArgument('arguments') ? $this->arguments['arguments'] : array();
        if ($this->hasArgument('action')) {
            $arguments['action'] = $this->arguments['action'];
        }
        if ($this->hasArgument('format') && $this->arguments['format'] !== '') {
            $arguments['format'] = $this->arguments['format'];
        }
        if ($this->hasArgument('addQueryStringMethod') && $this->arguments['addQueryStringMethod'] !== '') {
            $arguments['addQueryStringMethod'] = $this->arguments['addQueryStringMethod'];
        }
        return $uriBuilder->reset()->setArguments(array($argumentPrefix => $arguments))->setSection($this->arguments['section'])->setAddQueryString(TRUE)->setAddQueryStringMethod($this->arguments['addQueryStringMethod'])->setArgumentsToBeExcludedFromQueryString(array($argumentPrefix, 'cHash'))->setFormat($this->arguments['format'])->build();
    }

Where do you see anything about noCacheHash here? :)
