SiteForce and Ecommerce

[Nikhil.M]

Hey Folks,

                  I was looking on developing a sample ecommerce site using SIte Force. I did find a partner solution for this but i would love to do this on own using siteforce only.  So basically i have following two questions ?

1) Availibility Custom widgets for Paypal or other payment gateways. Where can I find them ?          

1.A ] -->  If there is None,  what are other ways to achieve it. The one I can see is adding paypal JavaScript API to files and uploading them.

2) Question 2 is also because of need of writing custom code and using custom query on custom data for all reasons. 

Description:- Currently siteforce exposes builtin data objects using data repeater elements. Data repeater elements in turn expose built in data object(Yes we can create new and custom). But I can only select certain fields in repeater view thus i cannot query multiple data sources. The solution I see is every time I need this I create a data view (object) and use it but don't feel comfortable with it since queries on data (much like SQL queries) are expected to change now and then.  

I would be highly grateful for the help.

Thanking you .

Love,

Nikhil
