## Found an invalid element type declaration in %s {#found-an-invalid-element-type-declaration-in-s}

```text
1264093642: Found an invalid element type declaration in %s. Type
"ObjectStorage" must not have an element type hint
(vendor\yourExtension\Domain\Model\yourModel)
```

## Solution {#solution}

In annotations use statement do not work in older TYPO3 versions.

Use:

```
use TYPO3\CMS\Extbase\Persistence\ObjectStorage

// ...

/**
* @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\vendor\yourExtension\Domain\Model\yourModel
* ...
*/

```

instead of

```
use TYPO3\CMS\Extbase\Persistence\ObjectStorage

// ...

/**
* @var ObjectStorage<\vendor\yourExtension\Domain\Model\yourModel>
* ...
*/

```
