Re: component parameter binding question
Are you using latest t5 snapshot or 5.0.X.X release?
If latest snapshot, just use like context=[user.id,user.name]
If not, there are 2 ways:
1. Do in java
public Object [] getContextValue() {
return new Object[2]{user.id, user.name};
}
2. Use list binding in t5commons library

Re: component parameter binding question
welcome:)
Like t:actionlink t:id=delete context=contextValueDelete/t:actionlink
Since context is prop binding, it will map getContextValue() method in java.

hi, about the remotelink minixs
hi i write a simple minixs call remotelink, it look like grails's remotelink. maybe minixs greate! you can simple use a href=# t:id=showme t:type=actionlink t:update=result t:mixins=remotelinkaction/a a href=# t:page=index t:type=pagelink t:update=result t:mixins=remotelinkpage/a div id=resultresult will show here./div but i confused by the return. My first question is : what should ajax action return? json? html fragment? xml? One of t5's benefit is you can use dreamweaver edit the tml”. In example code, pagelink work fine. because it return html. but actionlink is not perfect. My seconde question is : how to return html fragment in action.

Re: Invoking a custom show javascript method for a Zone
yeah I tried both show and update methods, didn't really work.
I finally got it to work by just adding the following to my event link.
onclick=editWindow.show('editWindow'); resizeWindow(500, 500);
So right after (or is it before) it calls the event method it also shows the
Window. Not ideal and it could potentially, show the window before Ajax event
could return the Zone content inside the window, but seems to work.
Tapestry certainly requires a lot of effort to get small things done.
Thanks Thiago for the Ajax.Responder recommendation, I'll look into it.

Re: PAGE Lifecycle vs COMPONENT render cycle
If Block Edit isn't a page and it isn't a component ... is there a predictable way to initialize it each time it is requested? In my case, I have a Hibernate entity ... with a reference @ManyToOne - to another entity. It is this child entity that has an edit block associated with it. When I go to EDIT the parent entity, I need to load all possible children entities into a select drop down and pick from them. Therefore, I need to refresh that edit block drop down each time it displays. Since I registered this block with the App Module - I don't explicitly reference it in the actual page displaying the BeanEditForm. Does that make sense? The BeanEditForm is instantiating the edit block behind the scenes. So, in the Java class associated with my edit block, I provide the model, I provide the encoder ... and I want to query for the latest list of enties. The Wiki example implements by the encoder and the model in the GenericSelectModel ... and then provides values as the model and encoder. If getValues queries the database and provides both the model and the encoder -- it gets invoked 2 times (the t:Select model and encoder parameters). So, I separated them - so I literally have a getModel and a getEncoder. Now, if I can't depend on events with this app block - I could put the query in one of these two - and I can see one hit before the other - but is that order guaranteed? If so - maybe I could compensate by checking a flag in either method and loading the list as necessary - but all that seems like a hack. It seems that my edit block needs a prepare event of some sort, and then the getModel and getEncoder methods are not burdened with also deciding if the data is present. Whoa - hope that wasn't too hard to follow. Please remember, I'm learning more about Tapestry all the time - so please erase all this and set me straight with the 'right' way. I seem to be going down a rabbit hole here if events don't apply to app blocks. On that note, pageAttached is currently firing in my EditBlock.java class. Were you implying (in an early post) that I should depend on that in all cases? That I'm just lucky here? I didn't quite understand this comment: A block is not a page nor a component. @PageAttached just worked because you declared it inside a page. since literally, void pageAttached() is declared and implemented in the BlockEdit.java - and not literally the page. declared it inside a page confuses me. Does that long explanation make sense? I really appreciate all of your time and input.

If it was the page where you put your edit and view blocks (let's call it BlocksPage), it wouldn't work, as BlocksPage is never rendered (never requested), just blocks and components declared inside it are. BlocksPage just exists because all Tapestry blocks needs to be declared inside some page. Does an edit block act like a page and not a component? A block is not a page nor a component. @PageAttached just worked because you declared it inside a page. And, am I missing something or is a PAGE lifecycle signficantly different than a COMPONENT lifecycle? A page is a component. It has the component lifecycle plus some events of its own. I had read and made the assumptions that PAGEs were actually COMPONENTs themselves and because they are special maybe I could see a PAGE having *additional* lifecycle methods - This is absolutely correct. but I wasn't ready for none of the COMPONENT lifecycle methods to trip. Again: a page used just to provide blocks does not react to component lifecycle events because it is not being rendered (it was not requested), just one of its blocks. I strongly suggest you to learn about events in Tapestry using writing very normal page (one that really renders HTML) and writing a simple component.

In my case, I have a Hibernate entity ... with a reference @ManyToOne -
to another entity. It is this child entity that has an edit block
associated
with it. When I go to EDIT the parent entity, I need to load all possible
children entities into a select drop down and pick from them.
Forget about events in this case.
Do it the easy way: you have to pass a SelectModel to the Select component
though the model parameter.
Something like:
select t:type=Select t:model=entityModel ...
Just do your initialization inside the getEntityModel() method:
SelectModel getEntityModel() {
// fetch children entities
// populate SelectModel
return selectModel;
}
Therefore, I need to refresh that edit block drop down each time it
displays. Since I registered this block with the App Module - I don't
explicitly reference it in the actual page displaying the BeanEditForm.
Does that make sense? The BeanEditForm is instantiating the edit block
behind the scenes.
You're right. You don't need to use a lifecycle event to refresh the
Select component because the model is requested everytime it (Select) is
rendered.
So, I separated them - so I literally have a getModel and a getEncoder.
Now, if I can't depend on events with this app block - I could put the
query in one of these two - and I can see one hit before the other - but
is that
order guaranteed?
Your encoder shouldn't depend on a pre-fetched list. Just fetch the
encoded object in your encoder.
On that note, pageAttached is currently firing in my EditBlock.java
class.
It is expected. Your page is activated when BeanEditForm gets a component
from it.
Were you implying (in an early post) that I should depend on that in all
cases?
I don't even know what you mean here, but the answer is no. :)
That I'm just lucky here? I didn't quite understand this comment:
since literally, void pageAttached() is declared and implemented in the
BlockEdit.java - and not literally the page. declared it inside a page
confuses me.
BlockEdit is a page that is not used as a regular page. Regular pages are
requested though HTTP. BlockEdit is used just to declare blocks.
Again: stop understanding lifecycle events in BlockEdit for a while and
try to learn them on regular pages and components.

Tapestry 5 haven't really abondened the old syntax, besides $content$ and $remove$, but they're easily replaced with simple components. I guess Howard (Tapestry creator and main developer) just wanted to create another syntax, one that is friendlier with XML editors (namespaces).

Re: PAGE Lifecycle vs COMPONENT render cycle
Your encoder shouldn't depend on a pre-fetched list. Just fetch the encoded object in your encoder. ... my encoder implements this method: public T toValue(String clientValue) So in my case, the encoder needs data from the database. I've spent cpu cycles in getModel() to pull a list of items. It seems like I should leverage that list when I hydrate the object back from it's screen representation to an actual object ... no? I guess - I could inject a dao or connection to the database into the ValueEncoder - but on first glance, that seems like overkill ... but - maybe I just need to get comfortable with it. Iv'e got the list right there. It can't have changed eh? To sum up, the main issue here is that the object I'm 'toValue'ing exists in the dbase (and in the model). The Wiki example for GenericSelectModel queries the database two times but I think it is redundant to do so. But again, if thats what the framework wants me to do - I'll work with it. I just needed to explore every option here to make sure I wasn't missing some BlockEdit event ... it seems natural when components and pages have events eh? But as natrual as I might intuit it, I do realize from your conversation that Blocks just aren't made or implemented that way. On that note, pageAttached is currently firing in my EditBlock.java class. It is expected. Your page is activated when BeanEditForm gets a component from it. My confusion here stems from my understanding that the edit block is NOT a page and you' ve mentioned a few times Your page is activatated ... and the event fires. I understand that event fires - but shouldn't it be handled by the PAGE and not the Edit Block? When a page includes a component - does the component suddenly handle that page's events? Likewise, I'm confused how the edit block (which is not a page or a component) is getting the pageAttached event. I understand it is a page event - I just don't understand why the Edit Block is handling it. Does it fire in the Page.java as well? Is there a diagram or somethign to see this? BlockEdit is a page that is not used as a regular page. Regular pages are requested though HTTP. BlockEdit is used just to declare blocks. Again: stop understanding lifecycle events in BlockEdit for a while and try to learn them on regular pages and components. Remember here, my goal right now is not to understand events per se but to get my custom select drop down working ... and it is indeed getting void pageAttached -- so that is why I must proceed down understanding lifecycle events for BlockEdit. Learning about events for pages and components is fine - but I need to know exactly how that applies to my current issue with the Edit Block. That is what I am practicing :) Thanks again, -Luther
Re: PAGE Lifecycle vs COMPONENT render cycle
Thiago,
You are like superman on this forum.
Thanks for spending so much time here ... I for one don't know what I'd do
without these discussions.
I know it is a tangent but I've posted to other groups like the Grails
nabble group and NEVER EVER get any responses. A framework is worthless to
me if I can't quickly get into a feedback loop of sorts when I run into
problem. Keeping this forum so active has a lot of intangible benefits for
Tapestry world domination and I just thought it'd be worth saying.
Keep up the good work and thanks again for all the time you spend here.

If Block Edit isn't a page and it isn't a component ... is there a
predictable way to initialize it each time it is requested?
In my case, I have a Hibernate entity ... with a reference @ManyToOne - to
another entity. It is this child entity that has an edit block associated
with it. When I go to EDIT the parent entity, I need to load all possible
children entities into a select drop down and pick from them.
Forget about events in this case.
Do it the easy way: you have to pass a SelectModel to the Select component
though the model parameter.
Something like:
select t:type=Select t:model=entityModel ...
Just do your initialization inside the getEntityModel() method:
SelectModel getEntityModel() {
// fetch children entities
// populate SelectModel
return selectModel;
}
Therefore, I need to refresh that edit block drop down each time it
displays. Since I registered this block with the App Module - I don't
explicitly reference it in the actual page displaying the BeanEditForm.
Does that make sense? The BeanEditForm is instantiating the edit block
behind the scenes.

Re: Tapestry 5.1 session invalidate misbehaving
Try switching the order of homePage.setIsSignOut(true) and

It looks like the homePage is being lazily evaluated right there, and

@Inject'ing Generic Services
The following is illegal Java ... so I cannot bind the following in my
AppModule:
binder.bind(ValueEncoderMovie.class,
GenericValueEncoderMovie.class);
binder.bind(ValueEncoderVideo.class,
GenericValueEncoderVideo.class);
binder.bind(ValueEncoderBook.class,
GenericValueEncoderBook.class);
binder.bind(ValueEncoderSong.class,
GenericValueEncoderSong.class);
Instead, I put the following into my AppModule:
binder.bind(ValueEncoder.class, GenericValueEncoder.class);
Can I safely @Inject this encoder into multiple/different pages?
class MoviePage
{
@Inject
private ValueEncoderMovie encoder;
class VideoPage
{
@Inject
private ValueEncoderVideo encoder;
If this is safe, although I only bound one instance, does it create a new
instance of the service for each GenericParameter type?
What should happen with something like this:
binder.bind(AbstractSelectModel.class, GenericSelectModel.class);
when there is no left-hand Generic to infer the Generic Parameter from:
class VideoPage
{
@Inject
private AbstractSelectModel model;

Java does not let you do that because of the way it implemented generics.
Anyway, Select (and maybe some other components) use ValueEncoderSource to
get a ValueEncoder for a given type. Take a look at
TapestryModule.contributeValueEncoderSource().

I guess this would work. But I suggest you to use
binder.bind(GenericSelectModel.class) (without the left-hand) and then
@Inject it like any other service.
This is a purely Tapestry-IoC thing, not exactly a Tapestry-Core (web

This would break something I love: the 1:1 relationship between page class and template and Tapestry. -- 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 -- View this message in context: http://www.nabble.com/T5%3A-alternative-template-tp22343366p22344065.html Sent from the Tapestry - User 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

Thanks, Inject page is an option, it will look like this: localhost/mycars localhost/mycarsaqua You're right . . . is there a way that, even I inject MyCarAqua, its url still localhost/mycars? I've never actually tried it, but I would create a block (or component) in each alternate page, create a getter that returns this block, inject the alternate pages in MyCars and use the Delegate component to render the block. This is similar to how BeanEditFrom/BeanEditor works: it renders components and blocks that are located in other pages. -- 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
T5: not all hibernate records saving
Hello,
I have a page that you load an excel file and read each line converting it to
records.
It works fine with no errors anywhere but out of 15855 lines it only actually
puts in 11272 records but my count on the loop shows 15855 and I cannot figure
out why these records are not saving with no errors being produced.
This is my basic logic(I have tried @CommitAfter but using
_session.beginTransaction and commit at each save actually produced some errors
I was able to fix that @CommitAfter did not)
Loop Lines{
ReadLine{
readCells(line)
}}
readCells(line){
loopCells{
read cell and put in corresponding field
fields that link, check if the field is in the foreign table, if not add
it and put id in field
}
}
Again I have tried using @CommitAfter however using the beingTransaction/commit
around each save produced more errors IE: invalid date format in a date field
etc. but now there are NO errors being thrown.
Are there errors I cannot see somehow?
Thanks,
--James

Re: templates changes from tapestry 4.1 to tapestry 5
A well established Tapestry style in Tap3 + Tap4 was: if jwcid=@Conditional condition=whatever ... /if I really liked that style, especially for teaching Tapestry and wanted to allow something that immediately understandable but even more concise.

Thanks for the quick answer to all of you. You're welcome! I was afraid I had made one of the biggest mistake in my life. Maybe you just made one of the best decisions in your life.. :) But can you tell me why the choice to abandon the old syntax has been taken: to me from the web designer point of view it is still the most clean way to implement the call to tapestry. Tapestry 5 haven't really abondened the old syntax, besides $content$ and $remove$, but they're easily replaced with simple components. I guess Howard (Tapestry creator and main developer) just wanted to create another syntax, one that is friendlier with XML editors (namespaces). I never use the t:componentName syntax in pages and almost never in components and I'm quite happy with it. :) -- 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 -- Howard M.
