Quick question(s) about UIX Data Providers...

Question

Hello,
I have a UIX Template that I use for all of the pages in my application. In this template, I have several data providers bound that are used to create the accessible tabs and links for navigation within the application.
When a data provider is called, does a constructor for the class get called before the actual method to get the Object/DataObject/DataObjectList is called? For the providers that I have defined (3), there is a common set of information that is needed by by each before it can provide the required data. All of these methods are in the same class. Each of these methods call an 'init()' method to retrieve the pre-requisite information. My problem is that when the page loads, as each method is called the 'init()' method is called. So 'init()' is called 3 times. Ideally, I'd like the logic in 'init()' to be executed once per page load. If I put this in a constructor for my provider, will it be executed on page load? Do UIX templates/pages created multiple class instances for data provider definitions?
How does classloading for data providers work? What is the best way to handle what I am trying to do?
Thank you.

Hi August Harrison,
UIX doesn't instantiate your data provider classes.
If you look closely, they are call to static methods.
When this returns a bean class - you would have taken care to instantiate them.
Data binding chapter in developers guide - Clearly state how every thing works.
There is a simple example which talks about a similar kind of scenario which you are refering to.
Hope this helps.
