RE: [T5] way to check if the application is entering or exiting from a page
Luca, I can see that the flash persistence strategy wouldn't quite work for you in that case. Actually, I'm doing something very similar, and I'm using regular session persistence and manually clearing things when necessary. I think that the rewind phase would map closely to the split between prepareForSubmit and prepareForRender for the form in terms of what you would want to set up. As an aside, have you looked at the wiki page for a Hibernate grid model? Depending on the size of your model, you might be better off with a model that only retrieves a page at a time. At some point, serializing that model into the session has to get intensive.

Re: [T5] way to check if the application is entering or exiting from a page
Hi Geoff, yes, I read those threads and I modeled my CRUD page using the suggestions listed on your Mk VI page. Thank you. As I was trying to explain to Jonathan Barker in my previous mail (ah, my poor english ;^) , my CRUD page already used @Persist("flash") to store the entity to modify. The problem was I was trying to do "too much things" in a single page thinking that the flash persistence could do the job (well, it works fine, but I had some conditions that were not compatible with that kind of persistence strategy). Anyway, I'm going to study Tapestry JumpStart to better understand T5 behaviour and page lifecycle.

Re: [T5] way to check if the application is entering or exiting from a page
Hi Jonathan, thank you for your suggestion. Yes, @Persist("flash") works fine for one object of for a set of objects that are always readed and showed into the page during the page rendering. And it's fine for a CRUD page that shows only the entity to manage. To learn T5, I was sperimenting a CRUD page composed by: 1) the list of objects to view / edit / delete rendered by the grid component. This list is alwasy visible. 2) over the grid, a zone that shows the data of selected entity using BeanDisplay or BeanEditor, depending if the user clicks the "view" or the "edit" link of the selected grid row. The entity data at #2 is displayed only if the user selects an entity from the above grid. When the user navigates the grid the application doesn't show any entity data. My goal was to provide the user an unique page to show all the entities, to view an existant entity or to create a new one from the same page, without leaving it. I was using the flash persistence mechanism to store both the entity list managed by the grid and the single entity selected by the user. This to avoid to make other queries to the database to retrieve that data when the user executes an action on that page (on the "rewind" phase, as I call it - but it's not the correct term). I noticed that when the application was not going to show a selected entity (#2), and the user selected another entity from the grid list, the application started to loose the "synchronization" between the grid's selected entity and the entity data showed below... it started to show the data of the old entity instead of the data of the new one. From my understanding, the value of a page property that uses @Persist("flash") is discarded from the session only after the application reads it to restore that property. So I think the old entity value was not discarded from the session because the application didn't show its data into the page. Obviously, this was my code fault ;^) I fixed the problem removing the @Persist("flash") annotation on the selected entity property and refactoring a bit the db initialization code.

Luca, Check the Form documentation for prepareForRender() and prepareForSubmit(). They can be better places to do heavy initialization than onActivate(). Also, take a look at @Persist("flash") which is meant to retain information for only one additional cycle (like the render after a form submit). You may find this is satisfactory for your "cache".

Re: [T5] way to check if the application is entering or exiting from a page
It sounds like what you are describing is @Persist("flash") which stores the object in the session until the next time its read (generally on the render pass) You can also take a look at http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/ComponentResourcesCommon.html#isRendering() Josh On Fri, Apr 18, 2008 at 7:24 AM, Luca Fossato <[EMAIL PROTECTED]> wrote: > Hi Chris, > > thank you. > > Sorry, I didn't explain well.

Re: [T5] way to check if the application is entering or exiting from a page
I'm sorry but I'm a bit confused by the terminology. I'm not a T4 user and the only thing I know about "rewind" is that it does not exist in T5. If you want to initialize business data, onActivate is the place to do it. If you want to handle form events, use event handlers to catch them. If you want to execute something at the end of a request within the context of the page, use pageDetached. I apologize if I'm missing your point. Perhaps someone else can chime in. chris Luca Fossato wrote: > Hi Chris, > > thank you. > > Sorry, I didn't explain well.

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.
