I am developing a portal page using the Liferay . I want to know the technical aspects of it. What exactly happens in the background when a portlet (either a custom built or an inbuilt) is dragged and dropped to the portal page. Curious to know. Please give me some insights.
Thanks
You might need to go through some basic portlet documentation first before start up here. Liferay itself is having nice documentation for developers, which you might want to checkout.
