RenderView execute a query

Question

Does anyone know why when you try to render a JSF view executes a database query?

I am listing a large paged list, as I have seen on:

http://wiki.apache.org/myfaces/WorkingWithLargeTables

I return data list it correctly (with the number of items I want), but I noticed that the RenderView run a query that gets all the data.

JSF does not do that. It's your own wrong code who does that. You're executing a SQL query in a getter method. Just do not do business job in getter method. Do it in (post)constructor or (action)listener method instead.
