Hi Chris, thank you.
Sorry, I didn't explain well. I intended from an "html page" point of view. Example: I have a page with a form. I'd like to track its lifecycle both for the "rewind" and "render" phase (I use T4 "rewind" term to indicate that the application is "exiting" from a page, and "render" to indicate the application is entering into the page) Here's an example log of the page lifecycle when I press the submit button of its form: --- cut here --- >> page is rendered; click the submit button of the form: ====> [TRANSACTION] transaction begin... myPage : pageAttached myPage : onActivate ** db initialization... myPage : onSuccessFromForm myPage: onPassivate (1 time) <==== [TRANSACTION] closed the entity manager... myPage : pageDetached << form submit was successfull; T5 redirects to the same page; ====> [TRANSACTION] transaction begin... myPage : pageAttached myPage : onActivate ** db initialization... myPage: onPassivate (x times) <==== [TRANSACTION] closed the entity manager... myPage : pageDetached --- cut here --- It seems to me that pageDetached is executed for both "rewind" and "render" phases. I'd like to know if there is an API or a strategy that I can use in onActivate method (or another initialization method) to know if I am exiting or entering the page. For example, I'd like to enter into a page and use onActivate() to initialize business data from the db and store it into a cache (session). Then, when I press the submit button of the form contained into the page, T5 will re-execute onActivate() again. At that moment, I'd like to know if I am in the "rewind" phase. If so, I could get the data from the cache (and then remove it from the cache, too) When T5 re-enters into the page and re-executes onActivate() (3rd time), I will check if the page is in "render" phase. If so I will query the db again to get "fresh" data.
