[T4] - Tapestry.bind basic Ajax example
Hi there,
I'm trying to do an XHR request using the same method as @DirectLink
component.
Here is the code:
script type=text/javascript
var xmlDoc = new ActiveXObject(Microsoft.XMLDOM);
var content;
function SendAjaxRequest() {
tapestry.bind
(/PhoneBook/app?component=%24DirectLinkamp;page=majaxamp;service=direct);
tapestry.load(xmlDoc);
content = xmlDoc.responseXML;
}
/script
p
a href=# onclick=SendAjaxRequest()click here/a
/p
The server-side component does work when called when using DirectLink, but
when clicking the link as coded above it doesn't.
1./ in IE7 it simply doesn't work but the page is displayed
2./ in Firefox it doesn't display the whole page and Firebug sends an error
message:uncaught exception: [Exception...' Component returned failure
code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [
nsIXMLHttpRequest.setRequestHeader]
I know, I know there must be something I have misunderstood but I am a bit
lost.
I don't want to use DirectLink because the result of the XHR must be used in
another javascript function.
Any help/remarks ?
Thanks
Loïc
Re: T4: creating search form and search result on one page
remove

setList( getService().search(getClient()) );

Re: how to have persistent data in querystring?
Well i guess the onPassivate-method isn't entirely out of the question since it gives a central place to handle this on the page-level as well. The tagging-variant seems nicer though. I thought i read somewhere in the documentation that a 'client-side persistence strategy' was on the horizon, which would include 'automagically' inserting persistent fields into the url. I can't find anymore where i've read it though. Since we're talking about updating / changing the url, in a somehwat related post i asked about possibilities for rewriting the url. (I havn't found time to try to resolve this) http://www.nabble.com/url-rewriting-in-Tapestry-5-tf4496726.html#a12823397 from that post: For example I want a Venue bean with name venueX and id=123 to show up as: http://test.com/venue/countryname/cityname/venux/123 Notice the countryname and cityname, which aren't fields of the Venue-page but are derived from the association venue-page-- venue-- city -- country. I think adapting the onPassivate-method for inserting these values into the url and onActivate() for only parsing the necessary fields from this url is all that is needed to get this to work, is this correct? btw: a Url-rwrite filtr for this won't work because i also want to have the translation the other way around.: not only from nice -- tapestry internal but also from tapestry internal -- nice. Url-rewrite only gives me the former. Later on i would like to strip the first /venue/ -- http://test.com/venue/countryname/cityname/venux/123 would become http://test.com/countryname/cityname/venux/123. This becomes harder, because tapestry now doesn't know anymore to which page to redirect. out-of-the-box it starts searching for a page with countryname. I guess for this I have to dig a little deeper. Hmm, in hindsight i believe this isn't at all a coherent post, with almost no question or conclusion to be found... consider this a kind of braindump ;-) cheers, Geert-Jan Josh Canfield-2 wrote: Ok, and you want to do this without implementing a passivate method on page B... That doesn't seem like a trivial problem to solve, especially in a safe and general way. I'm pretty sure nothing like that exists now, but I believe all the hooks are available to create your own annotations so you could do the implementation. If I were going to attempt this I'd start by looking at adding new activate/passivate methods via the class transform worker... There are a lot of issues to deal with... but you could start by taking a look at http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/services/ComponentClassTransformWorker.html and the source for the @Environmental annotation might help http://tapestry.apache.org/tapestry5/apidocs/src-html/org/apache/tapestry/internal/services/EnvironmentalWorker.html Good luck, Josh On 10/18/07, Britske [EMAIL PROTECTED] wrote: that would require a lot of manual labor for each and every link. btw: my question relates to T5. Say i had page B injected into page A. I could then initialize page B and return page B from some eventhandler on page A. What I would want to accomplish is that this automatically results in redirecting to page B (as normal) with the difference that the url of page B shows my predefined fields of page B in the url (I know I mentioned querystring in the subjectheader, i mean the path-part of the url) The mechanism could know this because at designtime I could have tagged the fields of page B that I wanted to include in the url. This would enable me to once define these fields at design-time and not having to worry about it later on. is anything like this out there, or planned at all?

after the onchange occurs, this is what happens in my app:

2. onActivate() is executed on the server, which I think proofs that
there
was indeed a redirect.
please don't get me wrong, I still think it's an elegant solution...

Why do you say a redirect happens ? Does your page refresh when you

It won't refresh because all your doing is call a javascript
function. There's no redirect.
Britske wrote:
since your example effectively calls a ActionLink through AJAX, a
redirect
DOES happen. It's the result of the ActionLink. If I'm seeing this
correctly
what then is the advantage of doing a call through AJAX or a
form.submit()
for the discussed purpose, since both result in a redirect?

The method i suggested is implemented so that you don't have to
submit the form. That's what AJAX is all about, you make a request
to the server and then update a portion of your page based on the

of for submission.
Britske wrote:
yeah indeed it is only called once when the template is rendered, I
discovered now. However i don't need to return a dynamic url or
whatever based on the
getTheLink-method.
what I need is a way to reliably catch a event at the server/java
side
(in
this case onChange) every time that event occurs. I don't want to
submit
my
form when that happens (otherwise I could use the method you
suggested)
but
I want to update some information on the current page and stay
there.
This means that i have to redirect to my currentpage with a couple
of
queryparameters in the url which depend on the selected fields in
the
form.
hmm, the more i think about it, I don't think i really need to catch
the
event server-side. I just redirect to the current page on onChange
using
javascript:window.location=... and parse the querystrings
correctly in
it.
hope this makes sense, thanks!

HugoPalma wrote:
That's the way it's supposed to be.
You only see the getTheLink method executed once because that
what it need to replace ${theLink} in your template with the
correct link that is returned from your method. This is done once
when the page renders. If you look at the rendered page source
you won't see ${theLink}
there, instead you will the the generated link to your listener.
Anyway, does it really matter how many times the getTheLink
method is invoked ? I think not. What really matters is that the
listener
method to which your getTheLink method should be returning the
URL to is
called whenever you call the sendRequest function.
Britske wrote:
thanks that works partially.
However, the event is only catched twice: 1. on pageload (??m
the sendRequest isn't called, but somehow the
getTheLink()-method is executed.)
2. the first time i send a onchange.
However after the first onchange all other onchange-event don't
get
getTheLink() executed, although sendRequest() is called on the
client-side
each time.
This is my relevant code:
in html: script
function sendRequest() {
alert(sendRequest reached);
new Ajax.Request('${theLink}',
{asynchronous:true,onSuccess:handleResponse});
} /script
...
select t:type=select t:model=themaList t:value=thema
onchange=sendRequest() name=thema id=thema tabindex=4
class=formElement/
in the page-class: public String getTheLink() {
System.out.println(catched!!);
return catched!;
}
Do you 've got any idea what causes this behavior?

Re: Tapestry 5 Roadmap
That is an incredible statement! There have been numerous discussions on this mailing list on the way T4 was made completely incompatible since it was going to incorporate the very best and then T5 was made even more incompatible to incorporate the latest. This has been a vexing issue with quite a few people and organizations who invested in T3/T4 based projects. By way of example, tell me how these products are not compatible within major releases: Websphere 4, 5, 6 WebLogic: 8, 9, 10 MySQL: 4, 5 Hibernate: 2, 3 There are some pieces that change and new features are introduced. But your don't have to do a major rewrite to use the newer version. As an example, if T5 were T4 + annotations, that would be a compatible release. But Howard has chosen to rewrite it from the ground up with no compatiblity concern. Well, thats his prerogative as this is open-source community driven development. If I want, I can take the T3 code base and establish my own framework. However, it also reflects on the popularly or lack of for Tapestry. This topic has been beaten to death and I don't wish to bring it up again. However, your point regarding versions was egregious. - Original Message - From: Christian Gruber [EMAIL PROTECTED] To: Tapestry users users@tapestry.apache.org Sent: Thursday, October 18, 2007 10:58 AM Subject: Re: Tapestry 5 Roadmap I'm not sure where incompatible releases comes in. No one releases 1.0 - 2.0 compatible releases except O/S vendors. That's typically what the large version number change means - these are incompatible.

The concern of the project should be to build out the business functionality using existing tools. If the tools in question are not yet released and in production, there is a very legitimate concern that the maintenance of the tool will become a partial focus. Tapestry may be a compelling offering technologically, but it has many other factors going against it - lack of a developer mindshare, incompatible releases in the past, etc. We have used Tapestry for big projects - but we are still using T3 since T4 and T5 are completely incompatible. You cannot push beta software past project stakeholders unless that beta software is also providing you with competitive advantage. T5 has some able competitors in Wicket and JSF/Stripes, etc while still lacking an ajax foundation for instance. So the competitive advantage is not clear cut. - Original Message - From: Alex Shneyderman [EMAIL PROTECTED] To: Tapestry users users@tapestry.apache.org Sent: Thursday, October 18, 2007 3:22 AM Subject: Re: Tapestry 5 Roadmap The one question I could not answer without looking ridiculous was What happens to our multi-million dollar project if Howard is hit by a bus tomorrow I think the question is irrelevant.

Re: t5 form submit not fired
thanks for mentioning the difference. In my case a dropdown-change causes a
result-set to reload based on a new query which is shown as the main result
on the page. Since this almost means rendering the entire page again, there
isn't much difference between streaming the diference as Json or whatever or
doing a complete reload. However ,i'm the first to admit that to do things
as populating dropdown boxes (autocomplete or whatever) or changing a
fraction of the page, AJAX is the way to go.
Thanks again,
Geert-Jan
Josh Canfield-2 wrote:
The whole point of AJAX is not having to return the whole page. You just
want to return the part of the page that needs updating. If selecting a
field in a drop down is supposed to add a dependant drop down (choose a
country changes possible address fields for instance), then you only
return
enough information for that field to be updated and use Javascript to
populate the field.
Your stream response can be XML, JSON, or HTML depending on what your
needs
are...

Could you eleborate what exactly you stream to the client in the

This must be the entire page right? You can't just stream changes back to
the client at least to my knowledge.
I'm curious if in your opinion streaming the response gives a noticable
performance difference than doing a redirect to the same page.

after the onchange occurs, this is what happens in my app:

2. onActivate() is executed on the server, which I think proofs that
there
was indeed a redirect.
please don't get me wrong, I still think it's an elegant solution...

It won't refresh because all your doing is call a javascript

There's no redirect.

since your example effectively calls a ActionLink through AJAX, a

but
I want to update some information on the current page and stay
there.
This means that i have to redirect to my currentpage with a couple
of
queryparameters in the url which depend on the selected fields in
the

hmm, the more i think about it, I don't think i really need to
catch
the

using
javascript:window.location=... and parse the querystrings

it.
hope this makes sense,

You only see the getTheLink method executed once because that
what
it
need to replace ${theLink} in your template with the correct link
that
is returned from your method. This is done once when the page
renders.
If you look at the rendered page source you won't see ${theLink}
there,
instead you will the the generated link to your listener.
Anyway, does it really matter how many times the getTheLink
method
is
invoked ? I think not. What really matters is that the listener
method
to which your getTheLink method should be returning the URL to is
called
whenever you call the sendRequest function.

Re: how to have persistent data in querystring?
your welcome;-) i have a look it myself. Josh Canfield-2 wrote: I haven't played with the client persistence strategy, but the documentation ( http://tapestry.formos.com/nightly/tapestry5/tapestry-core/guide/persist.html) says The field is persisted onto the client; you will see an additional query parameter in each URL (or an extra hidden field in each form). The nightly builds implementation is adding the client persisted fields into the url as a query parameter using a Base 64 encoded object stream... ( http://tapestry.formos.com/nightly/tapestry5/apidocs/src-html/org/apache/tapestry/internal/services/ClientPersistentFieldStorageImpl.html#line.41 ) If you want attractive URLs then I'd say this isn't what you are looking for... Although I got to learn a bit about it so thanks for asking the question :) Josh On 10/19/07, Britske [EMAIL PROTECTED] wrote: Well i guess the onPassivate-method isn't entirely out of the question since it gives a central place to handle this on the page-level as well. The tagging-variant seems nicer though. I thought i read somewhere in the documentation that a 'client-side persistence strategy' was on the horizon, which would include 'automagically' inserting persistent fields into the url. I can't find anymore where i've read it though. Since we're talking about updating / changing the url, in a somehwat related post i asked about possibilities for rewriting the url. (I havn't found time to try to resolve this) http://www.nabble.com/url-rewriting-in-Tapestry-5-tf4496726.html#a12823397 from that post: For example I want a Venue bean with name venueX and id=123 to show up as: http://test.com/venue/countryname/cityname/venux/123 Notice the countryname and cityname, which aren't fields of the Venue-page but are derived from the association venue-page-- venue-- city -- country. I think adapting the onPassivate-method for inserting these values into the url and onActivate() for only parsing the necessary fields from this url is all that is needed to get this to work, is this correct? btw: a Url-rwrite filtr for this won't work because i also want to have the translation the other way around.: not only from nice -- tapestry internal but also from tapestry internal -- nice. Url-rewrite only gives me the former. Later on i would like to strip the first /venue/ -- http://test.com/venue/countryname/cityname/venux/123 would become http://test.com/countryname/cityname/venux/123. This becomes harder, because tapestry now doesn't know anymore to which page to redirect. out-of-the-box it starts searching for a page with countryname. I guess for this I have to dig a little deeper. Hmm, in hindsight i believe this isn't at all a coherent post, with almost no question or conclusion to be found... consider this a kind of braindump ;-) cheers, Geert-Jan Josh Canfield-2 wrote: Ok, and you want to do this without implementing a passivate method on page B... That doesn't seem like a trivial problem to solve, especially in a safe and general way. I'm pretty sure nothing like that exists now, but I believe all the hooks are available to create your own annotations so you could do the implementation. If I were going to attempt this I'd start by looking at adding new activate/passivate methods via the class transform worker... There are a lot of issues to deal with... but you could start by taking a look at http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/services/ComponentClassTransformWorker.html and the source for the @Environmental annotation might help http://tapestry.apache.org/tapestry5/apidocs/src-html/org/apache/tapestry/internal/services/EnvironmentalWorker.html Good luck, Josh On 10/18/07, Britske [EMAIL PROTECTED] wrote: that would require a lot of manual labor for each and every link. btw: my question relates to T5.

Hi,
I have a form like following, it sets a persisted variable(country) in the
page class, initially it includes addressHK component in the page, when
user choose 'US' and click submit, the page is supposed to be refreshed
withh addressUS component included, but it never happen, it seems page was
never got re-rendered, any way to force the re-rendering

RE: Templates and t:body
Ok Found the answer as to why this was not working.
This may be trivial to seasoned users, but a hard catch for a newbie.
For components, such as the Header we have been talking about, the .java file
AND the .tml file need to both reside in the components package. I had been
putting the .tml file in the webroot and the .java for the component in
components. Moved the .tml to components package and it works now.

Tapestry mandates a certain organization to your classes.
If you page class is org.example.pages.MyPage then your component class (here,
Header) must be org.example.components.Header. The .pages. and .components.
part is very specific to Tapestry, hard-wired into the framework. Those are
packages that Tapestry scans at startup to locate page and component classes,
and such classes must exist there (for Tapestry to perform runtime code
transformation and hot class reloading).

T5: A Form without a Session
I'd like to add a form component to my page, I haven't found a way to do it without causing a session to be created when the page is first accessed. I'm fine if a session is created when the user actually submits the form, to handle validation etc. but some forms are rarely used and session overhead is just unwelcome. It looks like in the form component the default validator is @Persist'd which is causing the session to be created. I don't want to use client persistence if it's going to stuff the ugly base 64 encoded object in the url, although I haven't seen a way to change the persistence without changing the default persistence for everything... So, I've gone with a standard html form for the simple search box for now which is fine, but I'd like to use the t:form on other pages without forcing a session to be created when the form may not be submitted. Any thoughts? Thanks, Josh -- -- TheDailyTube.com. Sign up and get the best new videos on the internet delivered fresh to your inbox.
Re: how to have persistent data in querystring?
I haven't played with the client persistence strategy, but the documentation ( http://tapestry.formos.com/nightly/tapestry5/tapestry-core/guide/persist.html) says The field is persisted onto the client; you will see an additional query parameter in each URL (or an extra hidden field in each form). The nightly builds implementation is adding the client persisted fields into the url as a query parameter using a Base 64 encoded object stream... ( http://tapestry.formos.com/nightly/tapestry5/apidocs/src-html/org/apache/tapestry/internal/services/ClientPersistentFieldStorageImpl.html#line.41 ) If you want attractive URLs then I'd say this isn't what you are looking for... Although I got to learn a bit about it so thanks for asking the question :) Josh On 10/19/07, Britske [EMAIL PROTECTED] wrote: Well i guess the onPassivate-method isn't entirely out of the question since it gives a central place to handle this on the page-level as well. The tagging-variant seems nicer though. I thought i read somewhere in the documentation that a 'client-side persistence strategy' was on the horizon, which would include 'automagically' inserting persistent fields into the url. I can't find anymore where i've read it though. Since we're talking about updating / changing the url, in a somehwat related post i asked about possibilities for rewriting the url. (I havn't found time to try to resolve this) http://www.nabble.com/url-rewriting-in-Tapestry-5-tf4496726.html#a12823397 from that post: For example I want a Venue bean with name venueX and id=123 to show up as: http://test.com/venue/countryname/cityname/venux/123 Notice the countryname and cityname, which aren't fields of the Venue-page but are derived from the association venue-page-- venue-- city -- country. I think adapting the onPassivate-method for inserting these values into the url and onActivate() for only parsing the necessary fields from this url is all that is needed to get this to work, is this correct? btw: a Url-rwrite filtr for this won't work because i also want to have the translation the other way around.: not only from nice -- tapestry internal but also from tapestry internal -- nice. Url-rewrite only gives me the former. Later on i would like to strip the first /venue/ -- http://test.com/venue/countryname/cityname/venux/123 would become http://test.com/countryname/cityname/venux/123. This becomes harder, because tapestry now doesn't know anymore to which page to redirect. out-of-the-box it starts searching for a page with countryname. I guess for this I have to dig a little deeper.

Re: t5 form submit not fired
The whole point of AJAX is not having to return the whole page. You just
want to return the part of the page that needs updating. If selecting a
field in a drop down is supposed to add a dependant drop down (choose a
country changes possible address fields for instance), then you only return
enough information for that field to be updated and use Javascript to
populate the field.
Your stream response can be XML, JSON, or HTML depending on what your needs
are...

This must be the entire page right? You can't just stream changes back to

I'm curious if in your opinion streaming the response gives a noticable

If you look at the rendered page source you won't see ${theLink}

instead you will the the generated link to your listener.
Anyway, does it really matter how many times the getTheLink method

method
to which your getTheLink method should be returning the URL to is
called
whenever you call the sendRequest function.

However after the first onchange all other onchange-event don't

Re: Tapestry 5 Roadmap
Egregious? That demands and answer and perhaps an apology. Firstly, try porting and app from Weblogic Portal 8 to Weblogic Portal 9. It has conversion tools, but it's not compatible without up- conversion. Upconversion doesn't count. Then think of eclipse and the plugins geared for such. As to appservers themselves, core platforms have a higher bar for backwards compatibility and always have than component frameworks. Databases are also externally compatible only because they conform to an API they didn't write themselves (SQL92, etc.). I'm not sure about MySQL, but many SQL databases that have native APIs are not API compatible between releases when using that native API. And try to move the files over between databases, and you have to do an export and an import, because you can't just install an upgrade and have everything work. As I said, upconversion doesn't count. We're talking about a component framework, which is highly finicky. If you update the major versions, it's not unreasonable that existing components won't work. I mean Howard could have spent a lot of effort making a bridge or translation system to maintain compatibility (which is often how total rewrites gain their backwards compatibility... see windows), but he didn't (clearly) think that was worth his time. Of course, it's open-source, so you could do it, if you wanted it badly enough. Oh, and blah blah blah fork blah blah. You know that part. Regardless of all of this, at least one major apache project has this policy too, and that's from 2 minutes on google.http://apr.apache.org/versioning.html . Major versions mean incompatible releases. That's (in my experience, except for platforms themselves) often the (non-marketing) meaning of major versions. A few other examples: http://www.jmock.org/versioning.html http://xstream.codehaus.org/versioning.html http://developer.apple.com/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/VersionInformation.html http://wiki.eclipse.org/Version_Numbering ... oh, and most unix libraries. While not absolutely true in all cases, it is most certainly true in many cases, and is not unreasonable. Now apologize for your imputation, sir, for you are substantially, demonstrably incorrect.

By way of example, tell me how these products are not compatible within major releases: Websphere 4, 5, 6 WebLogic: 8, 9, 10 MySQL: 4, 5 Hibernate: 2, 3 There are some pieces that change and new features are introduced.

So the question is: Is it appropriate to have the global SymbolSource included when looking for component messages? Perhaps after the assets and application properties file? Some background on the issue: I'm adding a validator that takes an optional constraint. Rather than changing Validator to support this I just want to include a blank default constraint value for the validator in the library that contributes it. But I know this issue of looking up defaults is going to come up for other components. -- Dan Adams Senior Software Engineer Interactive Factory 617.235.5857 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- Jesse Kuhnert Tapestry/Dojo team member/developer Open source based consulting work centered around dojo/tapestry/tacos/hivemind. http://blog.opencomponentry.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
component list parameters?
Hi,
So I'm wondering if this is possible, and if not, has this been
thought of? I'm wanting to add a variable list of parameters to a
component, because it can take an arbitrary number of them and loop
overthem. So I'm looking at something like this.
A.tml
div xmlns:t=blah
t:b id=${literal:b1}
blah content 1
/t:b
t:b id=${literal:b2}
blah content 2
/t:b
/div
And then in A.java have something like
public class A {
@Parameter
private ListB _bs;
}
So then all the Bs that are direct children of A are added in as
parameters.
It woudl be less convenient, but still cool to do something like:
div xmlns:t=blah
t:parameter name=bs
t:b id=${literal:b1}
blah content 1
/t:b
t:b id=${literal:b2}
blah content 2
/t:b
/t:parameter
/div
But have each B handled seperately and added to the list. It would
make it much easier to do complex things like tabviews (with arbitrary
tabs) or other such things, I think, though there may be other ways to
skin this cat.
Christian.

AW: Tapestry 5 Roadmap
We have a T3 and a T4 Appliaction in production and hopefully will start a T5 development soon. I do not see a real big problem in this versions not beeing compatible. I also think you compare different kind of beasts if you compare Websphere with Tapestry. It's more like EJB 2.x to EJB 3 - and nobody cried out its incompatible. Compatibility can be the reason for stagnancy - and that is the one thing you can not balme Tapestry for :-) If you are happy with T4, just stay with it, it's maintained well, we just updated to 4.1.3 with no problem. just my 2 Cents, Max -Ursprüngliche Nachricht- Von: kranga [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 19. Oktober 2007 13:00 An: Tapestry users Betreff: Re: Tapestry 5 Roadmap That is an incredible statement! There have been numerous discussions on this mailing list on the way T4 was made completely incompatible since it was going to incorporate the very best and then T5 was made even more incompatible to incorporate the latest. This has been a vexing issue with quite a few people and organizations who invested in T3/T4 based projects. By way of example, tell me how these products are not compatible within major releases: Websphere 4, 5, 6 WebLogic: 8, 9, 10 MySQL: 4, 5 Hibernate: 2, 3 There are some pieces that change and new features are introduced. But your don't have to do a major rewrite to use the newer version. As an example, if T5 were T4 + annotations, that would be a compatible release. But Howard has chosen to rewrite it from the ground up with no compatiblity concern. Well, thats his prerogative as this is open-source community driven development. If I want, I can take the T3 code base and establish my own framework. However, it also reflects on the popularly or lack of for Tapestry. This topic has been beaten to death and I don't wish to bring it up again. However, your point regarding versions was egregious. - Original Message - From: Christian Gruber [EMAIL PROTECTED] To: Tapestry users users@tapestry.apache.org Sent: Thursday, October 18, 2007 10:58 AM Subject: Re: Tapestry 5 Roadmap I'm not sure where incompatible releases comes in. No one releases 1.0 - 2.0 compatible releases except O/S vendors. That's typically what the large version number change means - these are incompatible. That's not a strike against Tapestry, that's an industry expectation. Christian On 18-Oct-07, at 6:45 AM, kranga wrote: The question is very relevant. The concern of the project should be to build out the business functionality using existing tools. If the tools in question are not yet released and in production, there is a very legitimate concern that the maintenance of the tool will become a partial focus. Tapestry may be a compelling offering technologically, but it has many other factors going against it - lack of a developer mindshare, incompatible releases in the past, etc. We have used Tapestry for big projects - but we are still using T3 since T4 and T5 are completely incompatible. You cannot push beta software past project stakeholders unless that beta software is also providing you with competitive advantage. T5 has some able competitors in Wicket and JSF/Stripes, etc while still lacking an ajax foundation for instance. So the competitive advantage is not clear cut. - Original Message - From: Alex Shneyderman [EMAIL PROTECTED] To: Tapestry users users@tapestry.apache.org Sent: Thursday, October 18, 2007 3:22 AM Subject: Re: Tapestry 5 Roadmap The one question I could not answer without looking ridiculous was What happens to our multi-million dollar project if Howard is hit by a bus tomorrow I think the question is irrelevant. The question you should be answering: Is the current base usable enough to push through on the project?. A relevant after-question (if answer to the above is not exactly) to answer how easy it is to add the features you are missing if you have to. And how easy it is to poke through the tapestry's source-base to fix bugs that might exist and you will find during the project's development. If you can cross off HLS as your dependency then t5 is probably the best choice to make from what's available out there :-) Alex. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: template-expansion sees hibernate-entity as java.lang.Boolean?
Has anyone ever experienced something similar? or has anyone used hibernate
lazy-associations succesfully with expansions in T5?
I'm still not sure if it's a hibernate or a tapestry thing.
FYI; the error is happening in:
org.apache.tapestry.internal.services.PropertyConduitSourceImpl.readMethodForTerm(PropertyConduitSourceImpl.java:370)
and states:
Could not convert 'firstresult.poi.city.name' into a component parameter
binding: Class java.lang.Boolean does not contain a property named 'name'
(within property expression 'firstresult.poi.city.name').

first of all, excuse me for the post-flood, but I had some standing

this one goes:
I was on a roll until i wanted to include the name of a City-instance
through a template expansion, which gave the error:
Could not convert 'firstresult.poi.city.name' into a component parameter
binding: Class java.lang.Boolean does not contain a property named 'name'
(within property expression 'firstresult.poi.city.name').
However, city is of type City and not op type java.lang.Boolean!
The traversal goes through a POI and a City-class which are both mapped as
hibernate-entities.
the traversal poi.getCity() is a lazy association.
(for you hibernate gurus:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name=cityid, nullable=false)
@Cache(usage =
org.hibernate.annotations.CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
private City city;
my expansion looks like::
t:compositeBlockList t:id=comp1
t:parameter name=groupheader
div style=padding:5px
strong
${firstresult.poi.city.name}
/strong
/div
/t:parameter
/t:compositeBlockList
What is causing this error? Could the hibernate-entity City look like a
boolean (when reflection is used) before it is lazily fetched?? I can't
really imagine that but who knows? anyone?
thanks,
Geert-Jan

Re: t5 form submit not fired
A changes your method somehwat to return void -- redirect to current page
(Thanks Nick for mentioning the difference)
Could you eleborate what exactly you stream to the client in the
StreamReponse you give back?
This must be the entire page right? You can't just stream changes back to
the client at least to my knowledge.
I'm curious if in your opinion streaming the response gives a noticable
performance difference than doing a redirect to the same page.

It won't refresh because all your doing is call a javascript function.
There's no redirect.

yeah indeed it is only called once when the template is rendered, I

However i don't need to return a dynamic url or whatever based on the

what I need is a way to reliably catch a event at the server/java
side
(in
this case onChange) every time that event occurs. I don't want to
submit
my
form when that happens (otherwise I could use the method you
suggested)
but
I want to update some information on the current page and stay there.
This means that i have to redirect to my currentpage with a couple of
queryparameters in the url which depend on the selected fields in the
form.
hmm, the more i think about it, I don't think i really need to catch
the
event server-side. I just redirect to the current page on onChange
using
javascript:window.location=... and parse the querystrings correctly
in
it.
hope this makes sense,
thanks!

That's the way it's supposed to be.
You only see the getTheLink method executed once because that what
it
need to replace ${theLink} in your template with the correct link
that
is returned from your method. This is done once when the page
renders.
If you look at the rendered page source you won't see ${theLink}
there,
instead you will the the generated link to your listener.
Anyway, does it really matter how many times the getTheLink method
is
invoked ? I think not. What really matters is that the listener
method
to which your getTheLink method should be returning the URL to is
called
whenever you call the sendRequest function.
Britske wrote:
thanks that works partially.
However, the event is only catched twice:
1. on pageload (??m the sendRequest isn't called, but somehow the
getTheLink()-method is executed.)
2. the first time i send a onchange.
However after the first onchange all other onchange-event don't get
getTheLink() executed, although sendRequest() is called on the
client-side
each time.
This is my relevant code:
in html:
script
function sendRequest()
{
alert(sendRequest reached);
new Ajax.Request('${theLink}',
{asynchronous:true,onSuccess:handleResponse});
}
/script
...
select t:type=select t:model=themaList t:value=thema
onchange=sendRequest() name=thema id=thema tabindex=4
class=formElement/
in the page-class:
public String getTheLink()
{
System.out.println(catched!!);
return catched!;
}
Do you 've got any idea what causes this behavior?
Thanks,

Re: T5 Desired complex community components
Hi, here is a good place to start: http://www.jsfmatrix.net/ Click on the demo links to see what other frameworks have. The list of components is long... Regards, Borut 2007/10/17, Daniel Jue [EMAIL PROTECTED]: I was wondering what kind of components people are looking for that are not yet available as an open source example. T5 seems to have the simple html components pretty well covered, and we're all waiting anxiously for direct AJAX support. I was thinking simple things, up to the complexity of Pallete, Grid and BeanEditForm. I am using the EnhancedPallete (on the wiki) with good success, and I created an EnhancedGrid that allows for a component to be stuck in it's body (good for rows of totals that you want to align with the grid, but not have sorting apply to) Some other ideas that I've seen come up in the past: A Grid-independant Pager (sounds easy to do, but I haven't needed it yet) Fisheye Menu (Was part of Tacos?) Date Picker and Color Picker (I think they are available now) Progress Bar (would probably require AJAX to be any good) What about codified versions of these components? PivotTable (kind of like a Grid and Tree I guess) Tabs (Examples have been given, but a nice out-of-the-box one with CSS would be cool for tutorials) Dashboard (Something for dealing with IFrame layouts?) How about things that delve into areas normally reserved for web designers? (dynamic generation of Flash buttons would be a great starter example, using something like JGenerator) The Tapestry rounded-corners service is in this kind of gray area. I'm kind of hooked on the idea, especially if caching works as well as serving image files.

Just inject the WebRequest into your page and check for any unwanted
user agents in your setException() method.
@InjectObject(infrastructure:request)
public abstract WebRequest getRequest();
public void setException(Throwable t)
{
String userAgent = getRequest().getHeader(User-Agent);
if(!isUnwanted(userAgent))
{
// user agent is valid
