Is there a blog page with a QA modules structures analysis ( comparison between plugins, widgets, those using specifically DB , those creating pages or not , etc ) and perhaps a comparison with modules of other CMS ?
To save 2 or 3 days of reading core , thank you
I should want also to know if a widget used twice in a page is instancied once or twice and to understand why XXXX_page::process_request() is sometimes called twice
Edit : I traced process_request() and it is executed twice in dbsave just to show the page registred in qa_plugin, before any interaction. I want to know if it is related to the selected model I used.
