I am creating a custom module collection which has content as product grid serialization. I have referred article How to create the Product Grid Serializer Block In Custom module.
Mage::registry('current_[entity]')->getId(); to get the id. In my case I have used
Mage::registry('current_collections')->getId(); But i am getting error:
Fatal error: Call to a member function
getId()on a non-object in ..
How can I get current collections id from registry?
