Fatal error: Uncaught Error: Call to a member function addData() on null about magento-lts

[kiatng]

I cannot replicate this error.

Ref

magento-lts/app/code/core/Mage/Adminhtml/controllers/System/Convert/ProfileController.php

Lines 30 to 53 in c5b35aa

	protected function _initProfile($idFieldName = 'id')
	{
	$this->_title($this->__('System'))
	->_title($this->__('Import and Export'))
	->_title($this->__('Profiles'));
	$profileId = (int) $this->getRequest()->getParam($idFieldName);
	$profile = Mage::getModel('dataflow/profile');
	if ($profileId) {
	$profile->load($profileId);
	if (!$profile->getId()) {
	Mage::getSingleton('adminhtml/session')->addError(
	$this->__('The profile you are trying to save no longer exists')
	);
	$this->_redirect('*/*');
	return false;
	}
	}
	$profile->setAdminUserId(Mage::getSingleton('admin/session')->getUser()->getId());
	Mage::register('current_convert_profile', $profile);
	return $this;

which is called in

magento-lts/app/code/core/Mage/Adminhtml/controllers/System/Convert/ProfileController.php

Lines 108 to 110 in c5b35aa

	public function editAction()
	{
	$this->_initProfile();

$profile cannot be null because of line 37 $profile = Mage::getModel('dataflow/profile');.

It must be something else for you to get

Fatal error: Uncaught Error: Call to a member function addData() on null

Is the dataflow module disabled or is it missing? Regardless, it is more probable that something is wrong with your particular instance rather than OpenMage.

This proves the error based on the configuration mentioned in the initial post
