I have a g2 module that is registeringListners to GalleryEntity::save and GalleryEntity::delete.

These both listeners have been registered and only once.

However the handleEvent function is called twice for each Album saved by the user.

I am looking for any help to see that the function is called once per all events.

Thanks

Bharat.

what exact version of gallery 2 are you using? what core version?

and how did you register your event listener? (please post the code)
maybe reinstall your module.

Please fine the code pasted below.

Gallery version 2.2.3 (Latest download )

// from /modules/core/module.inc
$this->setRequiredCoreApi(array(7, 18));
$this->setRequiredModuleApi(array(3, 4));

// Constructor Code for Module
function UserActivityLogModule() {

global $gallery;
$this->setId('useractivitylog');
$this->setName($gallery->i18n('UserActivityLog'));
$this->setDescription($gallery->i18n('Provides useractivitylog about Gallery'));
$this->setVersion('0.9.0');
$this->setCallbacks('getSiteAdminViews');
$this->setCallbacks('registerEventListeners');
$this->setGroup('useractivitylog', $this->translate('User Activity Log'));
$this->setRequiredCoreApi(array(7, 18));
$this->setRequiredModuleApi(array(3, 4));
}

// Code for registering Listeners

function registerEventListeners() {

GalleryCoreApi::requireOnce('modules/useractivitylog/classes/UserActivityLogEvent.class');
$listener = new UserActivityLogEvent();
GalleryCoreApi::registerEventListener('GalleryEntity::save', $listener);
GalleryCoreApi::registerEventListener('GalleryEntity::delete', $listener);
GalleryCoreApi::registerEventListener('Gallery::Login', $listener);

}

Thanks for your time,

Deepak

- true, when adding a new album, there are two GalleryEntity::save events. one for the new album entity, and another for its parent album. we update the modification timestamp of an album when you add a sub-album or a sub-item.
- when editing an album, there's usually only one save event.

but... there's nothing that stops the framework to actually post 2 GalleryEntity::save events for the same entity for a single operation / action. some code could e.g. first create an entity, save it and then set some more properties/attributes on the entity and save it again.
but that's not the case in the above examples.
