The TinyMCE plugin of Croogo requires that you change the bootstrap of the plugin in order to activate it for your own plugins. It is a problem when you want to leverage the power of plugin automatic install / uninstall of croogo.
Consider using following code in your plugin bootstrap in order to get rid of tweaking the bootstrap that doesn't belong to you !
$extraTinymceActions = array();
$extraTinymceActions['YourController/admin_edit'] = array( array('elements'=>'YourModelContent'));
$initialTinymceActions =Â Configure::read('Tinymce.actions');
foreach ($extraTinymceActions AS $action => $settings) {
$initialTinymceActions[$action] = $settings;
$actionE = explode('/', $action);
Croogo::hookHelper($actionE['0'], 'Tinymce.Tinymce');
}
Configure::write('Tinymce.actions', $initialTinymceActions);
