TYPO3 Core

Got the same issue on Typo3 6.2.4:

Fatal error: Call to a member function getValue() on a non-object in .../typo3_src-6.2.4/typo3/sysext/form/Classes/Domain/Model/Attribute/AttributesAttribute.php on line 141

Is this still an issue in 6.2.9 and 7.0?
Can you please add instructions how this error message can be reproduced.

So far I've found one possibility to reproduce this.

Right now it is not possible to have the following setting.

1000 = SUBMIT
1000 {
  name = submit
}

When not supplying the property value one gets the above mentioned PHP error. Regarding to the SUBMIT element it should be possible not having a value.

We have to find even more use cases to come up with a proper solution.

@Christian: Would still be great if you could name us your use case.

There are 3 elements
RESET, SUBMIT and BUTTON
with code like this

TYPO3\CMS\Form\Domain\Model\Element\ButtonElement

public function setValue($value = '') {
    /** @var $localizationHandler \TYPO3\CMS\Form\Localization */
    $localizationHandler = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Form\\Localization');
    $oldValue = $this->getAttributeValue('value');
    ...
}

TYPO3\CMS\Form\Domain\Model\Element\AbstractElement

public function getAttributeValue($key) {
    /** @var $this->attributes \TYPO3\CMS\Form\Domain\Model\Attribute\AttributesAttribute */
    return $this->attributes->getValue($key);
}

\TYPO3\CMS\Form\Domain\Model\Attribute\AttributesAttribute

public function getValue($key) {
    return $this->getAttributeObjectByKey($key)->getValue();
}

If "value" is not set by Typoscript there is no object for $this->getAttributeObjectByKey('value')

My patchset ist tested with TYPO3 6.2.15-dev and 7.5.0-dev

Patch set 1 for branch TYPO3_6-2 of project Packages/TYPO3.CMS has been pushed to the review server.
It is available at http://review.typo3.org/42916
