RE: [T5.2] Constructor issue
I thought you should annotate the constructor you want the BEF to use with: @Inject ... to let Tap know which constructor to use. Regards, Jim. -Original Message- From: Michal Gruca [mailto:michalgr...@gmail.com] Sent: 05 October 2010 14:09 To: users@tapestry.apache.org Subject: [T5.2] Constructor issue Hi all. While preparing small showcase app, odd problem came out. When I created domain object with two constructors (first was default NOOP, second one had two parameters string and enum, it was meant for manual initialization only) and tried to use it with beaneditform I received exception that tapestry cannot handle my object creation. After removing parametrized constructor, error disappeared. It's bit odd IMHO. Tapestry should be capable to instantiate objects that have more than one constructor. Also @SessionState behaved weirdly. I was annotating java.util.Date. Error came up if I haven't instantiate object manually. Date has default constructor so Tapestry should be fine with constructing new Date on it's own. Maybe there are some reasons for that kind of behavior, but as I see it those are bugs. Should I create jira ticket for that? Tested on tapestry 5.2.1-snapshot.

Re: [T5.2] Constructor issue
> "Often, the BeanEditForm can create the object as needed (assuming a public, > no arguments constructor). " I believe the java docs are out of date. The change happened in a dependent class and the docs don't reflect the change. As Thiago said, the current strategy is to try to make the most complete object is built based on the available constructors. This lets you build beans that have access to services via constructor injection (like a service). I think failing to pick the correct constructor is a defect that Tapestry *should* solve. Principle 2 is Adaptive API, which should "adapt to your code". One option is to try them until you get one that works... this could lead to frustration during development if it's not obvious which constructor is getting called... Date has multiple constructors, so this is essentially the same problem. Josh On Tue, Oct 5, 2010 at 8:17 AM, Michal Gruca wrote: > > I must disagree. > But first to clarify.

I must disagree. But first to clarify. I described two cases. 1. BeanEditForm that cannot instantiate my object 2. Same issue for SSO creating java.util.Date AD 1. Quote from BeanEditForm doc: "Often, the BeanEditForm can create the object as needed (assuming a public, no arguments constructor). " So i provided such constructor in my entity (public no agrs) + I added another one that taken String and custom enum. What I assumed was that T5 will just use the one that it can use and leave other one alone. Due to that behavior no object handled to BeanEditForm should have more constructors than default one, or should be always created manually, and that is bit more than user need to do. Ad 2. Quote from linked documentation: "The first time you access an SSO, it is created automatically. Typically, the SSO will have a public no-args constructor ... but you may inject dependencies into the SSO via its constructor, as you can with a Tapestry IoC service implementation." In this case I wanted to use Date. Maybe not some real case scenario, so let's think about shoping basket for example. It may have default no args for T5 and second one if I want to instantiate it with some products. If T5 always takes constructor with most arguments it will fail on that scenario also, meaning that I will have to check boolean variable companion exist on every page on which I wan't to use my object. IMHO the best would be try to use no-args constructor or use one with most args and if You fail try another one and another till You succeed (meaning reach default no-args or error when there is no default no-args constructor).

T5.1 - authenticating page access & contributing a sevice
Hi All, I know there has been some discussion on best approaches in tapestry for authenticating access to web pages, so apologies if i have missed the answer to this: Initially I was tempted by the simplest approach - that is just store some "UserState" in the session via @SessionState and check this in onActivate(). However I feel using a "@RequiresLogin" annotation approach is a little more robust. I've been following Howard's tutorial here: http://tapestryjava.blogspot.com/2009/12/securing-tapestry-pages-with.html Now my question is two-fold: 1) How do I define and contribute a service in tapestry? 2) How does this guy know that the user _is_ authenticated? Should my service cache logged-in users itself, or can it access the session?

[T5.2] Constructor issue
Hi all. While preparing small showcase app, odd problem came out. When I created domain object with two constructors (first was default NOOP, second one had two parameters string and enum, it was meant for manual initialization only) and tried to use it with beaneditform I received exception that tapestry cannot handle my object creation. After removing parametrized constructor, error disappeared. It's bit odd IMHO. Tapestry should be capable to instantiate objects that have more than one constructor. Also @SessionState behaved weirdly. I was annotating java.util.Date. Error came up if I haven't instantiate object manually. Date has default constructor so Tapestry should be fine with constructing new Date on it's own. Maybe there are some reasons for that kind of behavior, but as I see it those are bugs. Should I create jira ticket for that? Tested on tapestry 5.2.1-snapshot. Link to application sources: https://bitbucket.org/mgruca/tjug_tapestry_30.09.10/downloads (last revision or two were stripped out from additional constructors. Content may be in Polish, but code should be all in En) -- View this message in context: http://tapestry-users.832.n2.nabble.com/T5-2-Constructor-issue-tp5603058p5603058.html Sent from the Tapestry Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Dynamically loading a component
Hi Omar, > I am trying to dynamically load a component which must be determined at > run time Do you need to define the component at runtime, or simply choose the component at runtime? For most cases, and I suspect yours too, all you need to do is choose from a number of existing components, if so then it is possible to do exactly what you require, but with a different approach. If you get your head around how composition works in Tapestry then its not so daunting. Blocks don't need to be defined in any particular order, they can be reused any number of times and precise rendering can be controlled. The solution I used was to create an 'assembly component' that assembles components via a tree, it works great and eliminates all those if / else's. But for any solution consider that somewhere you need to define components, and somehow choose them, whatever approach you use, you can't really escape this, so why not do this all in the same place? If you require recursion then do it in Java and assemble a tree to iterate over in your UI. Its not very much more work, just a different approach that also has the advantage that most of the core logic is done in Java so can be examined with a debugger. If you need more control over rendering then use the HeartBeat Environmental service, though I don't know of many good examples. cheers, Peter - Original Message - From: "Omar Carvajal" To: "Tapestry users" Sent: Tuesday, 5 October, 2010 07:19:27 GMT +02:00 Athens, Beirut, Bucharest, Istanbul Subject: Re: Dynamically loading a component This is horrible news since I have no way of knowing the components that needs to be called at design time (other wise I would use a ).

No problem at all. :) -- Thiago H. de Paula Figueiredo Independent Java, Apache Tapestry 5 and Hibernate consultant, developer, and instructor Owner, Ars Machina Tecnologia da Informação Ltda. http://www.arsmachina.com.br - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
[T5.2] Live class reloading not working with jetty
Since we upgraded to T5.2, live class reloading has not worked correctly, however if we downgrade it works fine. We're using Jetty kicked off using the runjettyrun plugin for Eclipse. When making just a simple tml change, using the running application again has a long pause before it does anything, and after a few requests it falls over out of permgen space. All of our developers are experiencing this, and it's a real shame that one of the major strengths of Tapestry is not working for us anymore. Is there something I need to change to get live class reloading working with T5.2? Thanks, Andy

Re: Dynamically loading a component
hi omar, this is not as horrible as it sounds ... testing gets a lot easier i have a fairly big T5 application with many modules. within this application i have many master - detail views where the detail view depends on the type of object within the master list and those types can be deployed as needed. ie. if i also deploy my order module my master view might show some order entry and if i dont deploy it it wont show up. if i click on this entry i want to be directed to a order specific page that is defined in another (web) module. therefore i created a service that contains a contribution of pages to the specific detail view which is used to render / create the appropriate links. i also have a BlockService (...Registry) where i can contribute blocks that should be reused in multiple pages and modules. so you always know in advance what you are gonna render. even the possible combinations. for more details take a look at the BeanEditor implementation. g, kris Von:Omar Carvajal An: Tapestry users Datum: 05.10.2010 06:19 Betreff:Re: Dynamically loading a component This is horrible news since I have no way of knowing the components that needs to be called at design time (other wise I would use a ). There is no magic that can be done to achieve this at all? Even if I have to use the internal services. Thanks for your quick response.

You cannot instantiate components in Java code, as Tapestry is static structure, dynamic behavior (including rendering). Take a look at http://tapestry.apache.org/tapestry5.1/cookbook/switch.html. It shows you how to render blocks dynamically, but the same approach can be used for components as well. You'll use @InjectComponent to get access in your Java code to the component instances declared in templates. > > -- > Thiago H. de Paula Figueiredo > Independent Java, Apache Tapestry 5 and Hibernate consultant, developer, and instructor > Owner, Ars Machina Tecnologia da Informação Ltda. > http://www.arsmachina.com.br > > - > To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org > For additional commands, e-mail: users-h...@tapestry.apache.org > - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: [t5] Problems with grid in a loop
Problem was due to the static -structure of tapestry. When re-rendering after a pager-link was pressed , the grid-source was always the source of last rendered grid. Solved by decorating Grid so that onInPlaceUpdate() triggers an event handled by the embedding component which thereby ensures that the right "source" is used for re-rendering the grid. I guess that there are better solutions for this, any recommendation appreciated Thanks Peter Hi, On a page i have a grid in a loop. When inPlace="true" clicking on a grids Pager-link always results in displaying the content of the last edited grid on the page, so i`m not able to move through the pages of the grids, and all grids display same information after clicking eachs grid-page-link. I assign unique id`s to each grid in the loop, but a look at the generated html reveals, that the id are assigned to the table of the grid, not to the sourroundig div. Is there a way to use grids in loops while inPlace=true?

Re: [T5.2, Google Application Engine] Can't get a method to be realized (i.e. invoke a method)
You'll find more information in the console log, but from the little bit you've shown me, it looks like your classpath is missing a referenced library, the one that provided class NestableRuntimeException.

Re: [T5.2] Principle 1, Static Structure Dynamic Behaviour
Hi Actually, there is no problem if you do that since you generate a valid action URL of your form and use request service to read parameter values. But this is not how Tapestry has been designed, Tapestry is a component oriented framework, not an action oriented framework. Static structure simply means that you cannot create *new* instances of component at runtime. That does not mean that you as a developer can't go beyond this principle and use Request.getParameter() method or even generate plain HTML in dom tree But if you use Tapestry components, you must be aware that even if you put a component inside a loop, the inner component will be 'rendered' n-times but ultimately there is only ONE instance of this component. 2010/10/5 iberck : > > Hi, thank you for the response > > So I don't understand the principle > > 1.

Re: [T5.2, Google Application Engine] Can't get a method to be realized (i.e. invoke a method)
Thanks for the advice you are totally correct. But this error also occurs on jetty. I made a mistake putting GAE in the subject. The error actually happens on both GAE and local jetty. I took my development locally to speed up the development process. Thank you for your time.
