Fileupload TYPO3 getting null on findAll()

Question

Hi have a backend module extension to upload files. Im using helhum fileupload for reference. File upload is successful. But the file filed of table updates the uid of sys_file_reference instead of no of files. Why it happens?

<f:form.upload  property="file" />

my reference is this Where can I set the table name and no_files in my table and sys_file reference

I got the solution for my problem. my model was

/**
     * Sets the file
     *
     * @param \TYPO3\CMS\Extbase\Domain\Model\FileReference $file
     * @return void
     */
    public function setFile(\TYPO3\CMS\Extbase\Domain\Model\FileReference $file = NULL)
    {
        $this->file = $file;
    }

I removed the type from argument list .Now its working fine.My updated code is below

/**
 * Sets the file
 *
 * @param \TYPO3\CMS\Extbase\Domain\Model\FileReference $file
 * @return void
 */
public function setFile($file = NULL)
{
    $this->file = $file;
}
