Add category attribute with WYSIWYG enabled - magento

Question

I'm following this tutorial: http://www.atwix.com/magento/add-category-attribute/
All is working well, attributes are added to categories, but without the WYSIWYG button below the field. WYSIWYG is enabled in System > Config > Content Management.
$this->startSetup();
$this->addAttribute('catalog_category', 'custom_att', array(
'group' => 'General',
'input' => 'textarea',
'type' => 'text',
'label' => 'My attribute',
'backend' => '',
'visible' => true,
'required' => false,
'wysiwyg_enabled' => true,
'visible_on_front' => true,
'is_html_allowed_on_front' => true,
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
));
$this->endSetup();
Whatever I try, WYSIWYG is not enabled for my attributes. Can anyone help? Or maybe there is a workaround for this?
EDIT: I searched other posts but all say that this code should add the WYSIWYG:
'wysiwyg_enabled' => true,
but it doesn't.

Answer 1

Tried to accomplish same task today and searching through magento code managed to complete my task with this code:
$productEntityTypeId = $installer->getEntityTypeId('catalog_product');
$installer->addAttribute($productEntityTypeId, 'some_text', array(
'group' => 'General',
'input' => 'textarea',
'type' => 'text',
'label' => 'Some Text',
'backend' => '',
'visible' => true,
'required' => false,
'visible_on_front' => true,
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
));
$installer->updateAttribute($productEntityTypeId, 'some_text', 'is_wysiwyg_enabled', 1);
$installer->updateAttribute($productEntityTypeId, 'some_text', 'is_html_allowed_on_front', 1);

Answer 2

This works:
$installer->updateAttribute('catalog_category', 'certifications', 'is_wysiwyg_enabled', 1);
$installer->updateAttribute('catalog_category', 'certifications', 'is_html_allowed_on_front', 1);

Answer 3

This worked for me:
$installer->addAttribute('catalog_category', 'short_description', array(
'type' => 'varchar',
'label' => 'Short Description',
'input' => 'textarea',
'default' => '',
'sort_order' => 1,
'required' => false,
'wysiwyg_enabled' => true,
'visible_on_front' => true,
'is_html_allowed_on_front' => true,
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE,
'group' => 'General Information',
));
Notice the following three entries:
'wysiwyg_enabled' => true,
'visible_on_front' => true,
'is_html_allowed_on_front' => true,
Using Magento CE 1.9.2.0.

Create php file in magento root directory and paste below code and run it from browser:-
ini_set('display_errors',0);
require_once 'app/Mage.php';
Mage::app();
$setup = new Mage_Eav_Model_Entity_Setup('core_setup');
function createNewAttributeSet($name) {
Mage::app('default');
$modelSet = Mage::getModel('eav/entity_attribute_set')
->setEntityTypeId(4) // 4 == "catalog/product"
->setAttributeSetName($name);
$modelSet->save();
$modelSet->initFromSkeleton(4)->save(); // same thing
}
// Replace your attribute name with "extra_info"
$setup->addAttribute('catalog_category', 'extra_info', array(
'group' => 'General Information',
'type' => 'text',
'backend' => '',
'frontend' => '',
'label' => 'Extra Information',
'wysiwyg_enabled' => true,
'visible_on_front' => true,
'is_html_allowed_on_front' => true,
'input' => 'textarea',
'class' => '',
'source' => 'eav/entity_attribute_source_boolean',
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE,
'visible' => 1,
'required' => 0,
'user_defined' => 0,
'default' => '',
'searchable' => 0,
'filterable' => 0,
'comparable' => 0,
'visible_on_front' => 0,
'unique' => 0,
'position' => 1,
));
$setup->updateAttribute('catalog_category', 'extra_info', 'is_wysiwyg_enabled', 1);
$setup->updateAttribute('catalog_category', 'extra_info', 'is_html_allowed_on_front', 1);
