Hi Tarek,
To start the discussion here is an old presentation from when Web View was first introduced to Gen which includes the reasons why it was added on top of the existing Web Generation (INTERNET) functionality: 25-Web_View.ppt
As you see Web View provides Web 2.0 functionality.
Amit Dwivedi can probably provide more input
If you decide to switch from Web generation to Web View you also need to review your HTML design.
Also please note that all Web View generation must be done from Gen Studio and not the Toolset: Webview TPMonitor option for Toolset
Hope that helps
Regards,
Lynn
