As far as I know, you can't return a page and an attachment in the same request. Using Javascript (window.location = "...";) in the returned page, you can instruct the user's browser to make another request (in this case, a file as an attachment). -- Thiago H. de Paula Figueiredo Independent Java consultant, developer, and instructor http://www.arsmachina.com.br/thiago - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Returning a file attachment and a page together in a request
I am a newbie to Tapestry and have a question: I have a downloads page that displays a list of files to the user. When the user clicks on any file link I need to do one of two things: 1) If the user is logged in, I need to send the selected file as an attachment to the browser 2) If the user is not logged in, I need to display the Login page. One the user is successfully logged in, I need to display the downloads page and also send the selected file as an attachment. I am able to do (1) using StreamResponse but not sure how to solve (2)- send a Page response back and a file as an attachment. Any help is greatly appreciated. Thanks, Raghu.

What is the good reference for ajax in T5? I did not find any good documentation from T5 website. Thanks. -- Haipeng Du Salt Lake City
Re: gridtable with hashmap
Hi Gutemberg, Grid needs a collection as its source parameter. HashMap (i.e. the Map-Interface) is no collection itsself, but provides two methods to get the collections "Collection values()" or "Set> entrySet()". Use one of those as source for Grid. One sidenote, HashMap does not garantuee the order of its elements. I.e. the order might be different on every iteration. That might not look very good to your users. You should consider switching the implementation to LinkedHashMap or even change the interface to SortedMap and use its implementation TreeMap.

I would agree if Tapestry-IoC wasn't flexible enough to support integration with other IoC/DI frameworks, but it is. Hint: take a look at the T-IoC' ModuleDef interface and how it's used in tapestry-spring. This brings them a lot of possibilities and integrations with third party frameworks / products that I do not see for tapestry. Could you give us some examples of what possibilities and integrations with third-party frameworks or products that you do not see for Tapestry? One could argument that this is a much more flexible approach than relying on one DI container. I don't think so. Look at how Spring is supported in Tapestry: it's absolutely transparent. When I need some Spring bean in my page, component, mixin or service, it is injected as if it was a Tapestry-IoC defined bean (service). My projects are built with Tapestry and transactions are handled by Spring-TX. In the future, when the Tapestry project will have it's own transaction support, my only changes my project will need are changing the Spring's @Transactional annotation for the corresponding Tapestry-TX annotations (which I guess will be the EJB 3 ones). Anything that needs my services/beans will not change. Tapestry very flexible architecture needs an IoC framework.

Thanks Easier than in the wiki? It should work in T5.1 just as T5. I don't recall any backward-incompatible changes from 5.0.18 to 5.1. I just think the line registry.performRegistryStartup(); is not needed now.

Re: Tapestry 5 and Event component.
It seems that Button is not designed for ajax.
I wonder why you don't try block/zone?
