Hi Peter,
Thanks for that. To try it I guess I have to upgrade to 5.0.17 ?

Ironic that you are pointed to yahoo for a solution when the advice they 
advocated to the community is to load scripts after markup, all for the false 
hope of a performance increase, which is ultimately incorrect and is creating 
these types of problems... your markup (hence actionlinks etc) should never be 
allowed to render until the scripts have loaded and the DOM is available.

See http://www.quirksmode.org/js/placejs.html at the bottom of the page:

Quote: "Placing scripts in the  makes sure that any functions are loaded 
before the buttons, links or other things that call them are loaded. If you put 
your scripts at the very end of a page, it is possible that a user already sees 
part of the page including a button with a JavaScript function call, while the 
rest of the page hasn't loaded yet. Result: user pushes button and gets 
JavaScript Error Message Alerts, because the browser can't find the script 
(yet). Unless there's a good reason to do otherwise, place your scripts in the 
"

Fortunately this is now configurable in Tapestry.

public static void contributeApplicationDefaults(
MappedConfiguration configuration) {
configuration.add(SymbolConstants.SCRIPTS_AT_TOP, "true");
}


And I bet your problem goes away.
Peter

Russell,
I you look at YUI's event model I belive it handles this better.

YUI Event - http://developer.yahoo.com/yui/event/ will allow you define
events before DOM Ready and queues them until after.

This should be a good way to solve this problem.

Is Ok. I read the results at
https://issues.apache.org/jira/browse/TAP5-1. I guess we will have to
roll our own. Can't have users clicking once and waiting and then going
"uh...did I click that"... I think it is better if there is either some

T5: Clicking on actionLonk with a zone parameter before page loads

[Russell Brown]

Hi,

I have some AJAX calls from actionLinks. If a user clicks on the
actionLink before the page is fully loaded I get the exception  

 

A component event handler method returned the value
[EMAIL PROTECTED] Return type
org.apache.tapestry5.internal.structure.BlockImpl can not be handled.
Configured return types are java.lang.Class, java.lang.String,
java.net.URL, org.apache.tapestry5.Link,
org.apache.tapestry5.StreamResponse,
org.apache.tapestry5.runtime.Component.

 

 

Is this something to do with javascript setting up the zones on load?

 

Is there a work around or a planned fix for this? We use ajax calls all
over the site and everyone can cause this kind of explosion if we have a
fast clicker.

 

Cheers

RE: T5 5.0.15 possible bug with forms with context on secure pages?

[Russell Brown]

>> Still, this sounds like a potential problem, because the page will

Does this mean I should raise a JIRA about this?

More importantly shouldn't a form on a https page have https as the
protocol in the action (that would solve the problem completely since
there would be no need to redirect and therefore no need to create an
onPassivate event to create a page render link)?

I'm not sure what your response means: are you acknowledging a bug in
the t:form component and the RequestSecurityManagerImpl and saying that
5.0.16 hides it a little so that there is no exception?

Cheers

5.0.16 does not have the same problem with null/blank values and
should handle this better.  Still, this sounds like a potential
problem, because the page will not have been activated, so it's hard
to expect it to passivate itself.

T5 5.0.15 possible bug with forms with context on secure pages?

[Russell Brown]

Hi Again,

Is this a bug or is it me? I have a page with the @Secure annotation. I
put a t:form with a context on the tml for the page.

 

Problem 1: The action url is
http://myhost:myport/MyPage.MyForm/MyContext.

 

Which leads to problem 2. The RequestSecurityManagerImpl method
checkForInsecureRequest(String) creates a page render link using the
page but then throws an exception java.lang.RuntimeException: Context
values (which are added to the request URL) may not be null or blank.

 

I guess this is because the onPassivate() method for the containing page
is called and by now it's properties are null since we are in a new
request...

 

What is the correct way to get around this? Shouldn't the form just
submit to https anyway since it is on an https page? And why does
createPageRenderLink cause the exception to be thrown, do I have to mark
ALL fields that are used in onPassivate as @Persist? And what happens to
the forms context? 

 

Any answers to any of the above would be greatly appreciated.

 

Cheers

Russell

T5 5.0.16 @Paramerter and @Property on same field

[Russell Brown]

Hi,

With the change in 5.0.16 that means it fails fast if you have both
@Property and getter and setter for a field we have removed quite a few
@Property annotations as we realize some fields were silently ignoring
the existing getters and setters (which sometimes have a tiny bit of
logic in).

 

The odd thing is that now we are getting an exception. Does @Parameter
transform a field into a final field now? I don't see any reference to
same in the release notes.

 

The exception has at its root:

 

"Caused by: org.apache.tapestry5.ioc.internal.util.TapestryException:
Binding LiteralBinding[cssClassName: slotCta] is read-only.  

at
org.apache.tapestry5.internal.bindings.AbstractBinding.set(AbstractBindi
ng.java:45) 

 

at
org.apache.tapestry5.internal.structure.InternalComponentResourcesImpl.w
riteParameter(InternalComponentResourcesImpl.java:329)"

 

 

I am was advising the team in general not to use @Property any more due
to the nature of the gotchas but this would rather put a hole in that. I
prefer handcoded getters and setters to simplify unit testing...

 

Any ideas?

 

Many thanks is advance

RE: T5 document is wrong or the code is wrong or I am wrong and confused. (Return Link from action Link handler)

Hi,
Yes Link from AJAX request. Like the docs say. Seems like a really good feature 
to cancel all the AJAXing and just redirect the browser. Doesn't work in 
5.0.15. I will let you know Monday if it works in 5.0.16. I like  moving target.

Perhaps I misunderstand your problem - are you trying to return a Link  
from an Ajax event handler?
If Ajax is not involved then this might help:

I am having trouble understanding your answer: are you saying if I move to 
5.0.16 the feature will work? Are you also saying that the documentation 
reflects 5.0.16 and not the stable release? Having read the release notes you

The docs on the website reflect the latest stable release except for
when a new release is being voted, as is the case currently.  The
functionality you're having trouble with is part of 5.0.16.

We are very good about every change being committed against a JIRA
issue, so the release notes:

http://tapestry.apache.org/tapestry5/release-notes.html

Are a very good guide to figuring out what feature went in when.

T5 document is wrong or the code is wrong or I am wrong and confused. (Return Link from action Link handler)

[Russell Brown]

Hi,

So the documentation here
http://tapestry.apache.org/tapestry5/guide/ajax.html says:-

 


"Event Handler Return Types


In a traditional request, the return value of an event handler method is
used to determine which page will render a complete response, and a
redirect is sent to the client to render the new page (as a new
request).

With a Zone update, the return value is used to render a partial
response within the same request.

This return value should be an injected component or block. The value
will be rendered, and that markup will be used on the client side to
update the Zone's .

An event handler may return a Link
  and the client will be redirected to that link.

Returning a page name (as a String), or a page class, or a page instance
will also send a redirect to the indicated page.

"

 

But my method that returns a Link says throws this exception

 

Caused by: java.lang.RuntimeException: A component event handler method
returned the value http://localhost:8080/home/ Return type
org.apache.tapestry5.internal.services.LinkImpl can not be handled.
Configured return types are org.apache.tapestry5.StreamResponse,
org.apache.tapestry5.json.JSONArray,
org.apache.tapestry5.json.JSONObject,
org.apache.tapestry5.runtime.Component,
org.apache.tapestry5.runtime.RenderCommand.

  

 

The documentation and the exception seem to be mutually exclusive, or is
there a 3rd way I am missing? Any ideas appreciated as it has been a
pretty unedifying afternoon of head against T5 brick walling.

 

Cheers

Why not use an activation context on the page to persist your parameters

T5: component gets access to Page Context

[Russell Brown]

Hi,

 

If I have a component in a page and I want to get to the pages context
is the ONLY way to have the page pass the pertinent context information
to the context as a parameter? What if there component is nested further
down the tree? Will a context info I need to be passed through parent
components? Even if it is irrelevant to them, or is there some direct
way of accessing the containing page's activation context (without
injecting the request and hacking  it out of there)?

 

Cheers

 

Russell

RE: Deep linking to tapestry pages from jps. Conversion

[Russell Brown]

Hi Borut,
We are migrating a Struts app at the moment so if you have any specific 
questions about stuff then fire away as we _may_ have solved one or two 
problems that you might face already. 

Such a guide would be a good idea: it is ideal to start a nice new app with a 
nice new framework but in the real world most people are working on legacy 
applications and migration is the normal use case. If T5 wants any real 
penetration then thinking about migrating users from Struts to T5 is a must. 
Although it is essentially a "marketing" problem and most developers struggle 
with marketing.

RE: T5: class used as value in t:loop must implement serializable?

[Russell Brown]

Answered my own question: further up the stack is a t:form component.
This component has found itself nested in a t:form component so in this
instance then the answer would seem to be "yes".

Thing is, right, unless you *know* for a fact your component won't be
nested in a t:form somewhere down the line you must make sure that your
component nests a t:loop that everything within the loop is
serializable? Is that right?

RE: tapestry 5 without sessions

[Russell Brown]

One thing to notice is that a form component has a validation tracker
and that is persisted in session behind the scenes. To avoid this we
provide a new validation tracker to every form like this:

Tml:->




Class: ->

/**
 * This is essentially a hack to stop the session from being
created. HLS told us to return a new
 * [EMAIL PROTECTED] ValidationTrackerImpl} per request
 * 
 * @return
 */
public ValidationTracker getValidationTracker() {
return new ValidationTrackerImpl();
}

public void setValidationTracker(ValidationTracker
validationTracker) {
// NO OP
}

That is the one tip I can offer apart from don't use persist, use
onActivate and onPassivate (as other poster said).

If you do come across any other scalability gotchas please post them. I
will do likewise if we discover any as we move forward with our
development.

Cheers

Subject: tapestry 5 without sessions

I'm about to start a large project and intend to use tapestry 5 but want
to
avoid using sessions due to scalability.  The only issue I can see is
losing
form data when the validation fails because of the redirect after the
post.

I've noticed the property
tapestry.suppress-redirect-from-action-requests
but in general I prefer this behaviour so I'd rather not use this if
there
is an alternative. Plus the documentation says 'This option should be
used
with care' which makes me nervous about using it at all.

The only time I don't want a redirect occurring is when validation fails
and
form data needs to be presented back to the user without being
persisted. Is
there a way to do this because being forced to use session just for this
reason doesn't seem worthwhile.

I'm wondering what other peoples thoughts and approaches were to this
problem.
Has anyone used tapestry5 without sessions?


Cheers,

Jack

T5: Access Page context from sub component

[Russell Brown]

Hi,

When I have an action link in a sub component I notice that the query
string ?t:ac=some/context/stuff/from/the/page is appended to the link
target. I'd like to manipulate that very context in my component and so
far I have been passing its elements down through a nest of components.
Is there a way to access it programmatically without directly injecting
the request and grabbing it from there?

You don't need to create a component from that, just stop thinking JSP  
when coding Tapestry. :)
In Tapestry, all the logic is implemented in pages classes, with no
logic  
in templates. And this is a very good thing, as the logic is easily
tested  
when implemented in classes. ;)

Not tested, but hopefully it will give you an idea on how to do that:

YourClass.java:

private ItemType item;

@Property /* so we don't need to provide the getter and setter, as they

don't have any logic */
private ItemType lastItem;

public ItemType getItem() {
return item;
}

public void ItemType setItem(ItemType item) {
lastItem = this.item;
this.item = item;
}

public List getList() {
return ...; // list to be iterated
}

public boolean isNotEmpty() {
return lastItem != null; // or any other logic
}

YourTemplate.tml:



 




If you don't get it, tell us. :)

RE: T5: equivelent of c:set ?

[Russell Brown]

Ok...an example

In jsp












So in the above example I have a variable available called "someVar"
that is set to the value of the previous myItem's myProperty value. But
with T5 and the var binding I get THIS iterations value. The SCOPE of
the VAR binding is not wide enough for me. So is there an equivalent in
Tapestry or do I have to create a component and call it like this













And then have code like 

@Component(id="someVar")
Private MySetComponentType someVar;


And the MySetComponentType is just 

Public class MySetComponentType {
@Parameter
@Property
Private String value;

}


But there just has to be a better way. Right?

Cheers for taking the time

if you use the "var:" prefix in your template you do not need a
corresponding property in your page/component. and you 
can use this variable in your template multiple times (as in the
loop example). tapestry will generate a property on the fly
during rendering for this variable.

if you declare your components purley in your template
you can also pass in the parameters it accepts as well. 
 and it should work with var: variables as well.

eg.

AFAIK you cannot access the value of the "var:" variables in your
pages or components.

hope this helps... maybe you can post an example... as posted by thiago

You can do that in Tapestry, but you just do it in a different way. 
Remember that the page class properties are always available to the 
template.

Please post a JSP example of what you're trying to accomplish so we'll

Thanks. I have already.

The docs say "Allows a render variable of the component to be read or
updated." Updated how, when? What is a render variable? A variable in a
template without a corresponding property? But I want to SET a property
of my component from the template...

As far as I can see it is only of use in a loop in which case it is set
at the start of the iteration. How about iteration idioms that involve
setting a value at the end of the iteration to be used by the next
iteration? It is fairly common to see and trivial in struts, jsps,

Hi,

If I want to set some property from within the component template is
that possible in Tapestry 5? Something like the c:set tag is JSP jstl?
Or do you just write a set component and have it as a property of the

RE: T5: t:select how to disable and re-enable

[Russell Brown]

Thanks guys,
Like I said in the initial post: I am doing this on the client side, because I 
have to.

Doing it on the clientside involves jumping through some hoops. Namely, inject 
the component to get its id and then add some javascript to the page using 
RenderSupport. No problem. It iss done... but I am just wondering aloud on the 
list why I need to jump through the hoops. Why tapestry 5 has this feature that 
costs me a lot to circumvent and benefits me very little? I'd just like to know 
in what cases there is a benefit to this behavior so that I don't feel like I 
am being made to suffer (just like I used to in struts)

it is not enough to enable the select box only on the client site.
because if you render a select component with disabled="true"
tapestry wont even "register" the necessary event handler to 
process the submission.

in tapestry 5 words: no ProcessSubmission component 
event will be serialized into the form thus no values will be 
processed. :)  (see Select->AbstractField component source code)

i see two possibilities: as mentiond by andy do everything on the
client side or do a ajax request (zone) updatind the select component
with disabled="false".

Maybe it's possible that you disable your select only clientside?

Seems like the only way. Boo. So I have to use the RenderSupport and get the 
client Id using the tapestry tricks and inject the component and write a fair 
bit of code just to side step a pretty bizarre and unexplained feature. Sure, 
it is possible and it works. But the question still standswhy?

T5: t:select how to disable and re-enable

[Russell Brown]

Hi,
I am using a T5 select component. When the form renders I wish the select to be 
disabled so I use disabled="true" parameter. However, some javascript causes 
the field to become enabled. If this happens however the value selected does 
not get sent into the property of the component. I am assuming this is thanks 
to the "feature" decribed here 
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Select.html
 thussly : 

"If true, then the field will render out with a disabled attribute (to turn off 
client-side behavior). Further, a disabled field ignores any value in the 
request when the form is submitted. "

So how to set the select value to disabled initially but not make it stay that 
way for ever?

Thanks in advance for your ideas, I have resorted to adding a little javascript 
that sets it so on load but that is a bit of hack for some fairly simple 
functionality.

Any reason WHY "Further, a disabled field ignores any value in the request when 
the form is submitted." this seems to offer zero advantage and loads of problems

Russell,
Are you using a main class to start your app?

If so  you need the line

 // Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{"-org.mortbay.jetty.plus.jaas.", "org.mortbay.jetty."});


In your class - see http://wiki.apache.org/tapestry/Tapestry5RunViaMain.

The reason is Jetty thinks slf4j is a 'server' class and in line with
the J2EE specification is stops it 'leaking' into web application
classloaders. This line tells it to let it through.

THis only effects T5 pages/components when you are using the
runViaMain method. It won't effect your non T5 classes as they are
loaded in the system classloader. Whereas the enhanced T5
pages/components load in the web class loader.

Thanks

Ben

RE: T5: 5.0.14 Bizarre ClassNotFoundException

[Russell Brown]

Hi Toby,
Thanks for that. I have suspicion I have a maven nightmare on my hands. I have 
used maven's "exlusion" to exclude SLF4j from being included by Tapestry as we 
want to control the version. I can see that the Pages and Components use a 
different class loader, I guess they have to for all that run time 
transformation that is going on but they _should_ be able to load classes that 
their parents can in my humble opinion.

I've just had a double, triple check and there is only one SLF4j jar on the 
classpath, the one I intended to have there. The one that my Struts actions can 
access.

I'll keep digging for now. Thanks for the help, it does confirm that my main 
problem is probably maven/dependancy based but exacerbated by Tapestry's class 
loading.

Cheers

Hi Russel,

Just a thought but it might be worth checking your classpath. T5 will pull
SLF4 into the classpath anyway so you could have included it twice. Because
T5 uses a separate classloader for Pages and Components it may be getting
confused. I've run into similar problems before.

T5: 5.0.14 Bizarre ClassNotFoundException

[Russell Brown]

Hi,
Not sure if this is totally a T5 issue but I am just seeing if anyone has seen 
this. I have a page that uses the Form component but when I call the page I get 
a ClassNotFoundException for org.slf4j.Logger. Now I know that the class is on 
the classpath as I have Struts app running in the same container and Calling 
Class.forName("org.slf4j.Logger", true, this.getClass().getClassLoader()) in a 
struts action yields a class but the toClass method in 
org.apache.tapestry5.internal.services.InternalClassTransformationImpl throws a 
ClassNotFoundException.

If I change the code in that class to use the parent of the parent class loader 
then the class is found.

Any ideas? Is this a bug, is there some way to make Tapestry's class loader 
aware of the Class?

Cheers

Russell

Well the 'it' was the class, or moreover the approach but that does result in 
specifically the symbol names in this instance, so: Yes that it, or they.

Fair enough then. I did it differently (since I'd like to know at start up if 
my app is miss-configured), I guess the solution needs to fit the requirements.

I still think you need to T5-alize it and make it case insensitive.

And why oh why oh why bury your exceptions and just log them? Why not let them 
bubble up so that they are thrown? Otherwise you will just get a symbol 
exception which is hard to figure out later on?

Nice, thanks for that one.

I would suggest to add that "PropertiesFileSymbolProvider" class also to 
main Tapestry5 distribution. And I took the liberty to refactor the 
symbol provider implementation in wiki to be more generic: it now 
accepts also URL and InputStream as possible places to load the properties.

PS. Sorry about the curly braces style in the refactored class - my 
eclipse autoformatted it to my coding style and I was too lazy to change 
it back

RE: [T5] loading tapestry configuration from properties file?

[Russell Brown]

You can write a Property File based symbol provider implementation (or that is 
what I did). Mine just takes an array of strings (which are properties files on 
the class path) and loads them into a map. Then your imp los 
SymbolProvider.valueForSymbol(String) is just yourSymbolMap.get(String). To 
keep it all Tapestry 5esque I call .toLowerCase() on all my keys before I put 
them in the map and toLowerCase() on the symbol I am looking up.

Hi,

I know Tapestry5 really pushes the convention-over-configuration
approach, but lets face it - in every non-trivial application you
eventually need to configure stuff. If not directly tapestry-related
properties, then at least your application.

By default, Tapestry seems to suggest that everybody should start using
web.xml for all such configuration purposes. At least that's the
impression that I get when looking at
http://tapestry.apache.org/tapestry5/guide/conf.html.

However, I don't particularly like the overly-verbose web.xml style of
configuring plain-simple properties - I'd rather use (the much more
concise) properties file syntax for that.

Is it possible to tell to Tapestry: "please load all properties from
WEB-INF/myapp.properties"?

If not, can someone give some pointers on how to implement it?
(it would also be a welcome "out-of-the-box" addition to Tapestry5)

Rgds,
Neeme

RE: T5: testing using PageTester and EasyMock

Right. I done it. I'll write a wiki post about it this evening.

In short, only services with an interface are wrapped in the
ObjectCreator proxy. I just use reflection to grab the ObjectCreator
field from the proxy and fire its create method and use the resultant
service.

Alex,
Yeah. I think that the approach you outline may well work but is
unworkable   (if you know what I mean). I hold out for some way of
stripping the proxy from my mock service (using reflection to fire the
Object Creators create method and using the un proxied mock).

The problem with training the mock in the test case is that you don't
get the mock from the registry, you get a proxy wrapped mock.

Russell,
   this is just speculation, as I haven't tried this on my own, but it
seems
to me that you'll have to do the EasyMock setup & training inside your
test
module, e.g. :

@SubModule( { MyAppModule.class })
MyAppTestModule

public static MyService buildMyService () {
   MyService myMockService =
EasyMock.createMock(MyService.class);
   EasyMock.expect(myMockService.
expensiveExternalMethodCallToCreditCardGatewayIdontReallyWantToTest(myCa
rdNumber)).andReturn(authCode);

}

Unfortunately, with an approach like this, you'd have to have different
"buildMyService" method for each test case for which you need to train
the
Mock... I'm not sure how that would work, maybe you can have your
MyAppTestModule use something from the test case that will train the
myMockService based on the individual testcase expectations.

 Keep us posted on how this works.

RE: T5: testing using PageTester and EasyMock

[Russell Brown]

Hi Peter,
Thanks for that. That is just normal EasyMock testing isn't it? I don't see 
where tapestry comes into that at all? You are creating the instances of all 
the classes and you are creating the instance of the class under test aren't 
you? Where is the PageTester and Tapestry IoC and all that (or have you missed 
some code, or am I missing something?)



What I meant was this:- In the src/main/java tree I have MyAppModule which has 
some services like

Binder.bind(MyService.class, MyExpensiveExternalImpl.class)

But in my src/test/java tree I have 

@SubModule( { MyAppModule.class })
MyAppTestModule

public static MyService buildMyService () {
return EasyMock.createMock(MyService.class);
}


(In the actual App the MyService Impl will be provided by Spring but that is by 
the by)

So that when I use PageTester in my tests I can go

MyService myMockService = pageTester.getRegistry().getService(MyService.class);

EasyMock.expect(myMockService.expensiveExternalMethodCallToCreditCardGatewayIdontReallyWantToTest(myCardNumber)).andReturn(authCode);


But the problem is...the registry returns a Proxy that contains a 
JustInTimeObjectCreator so EasyMock won't have no truck with my mock service. 
Boo.

Russell

Hi all,

I haven't got around to using PageTester yet, but I started using Easymock for 
my IoC services recently... Its quite amazing how you can create a full blown

service proxies are all interfaces in Tapestry.

RE: T5: testing using PageTester and EasyMock

[Russell Brown]

Hi Alex,
Testing pages as POJOs is quite simple. You can roll your own very,
very, very simple service injector and inject EasyMock services into the
pojo. I have done it using reflection. So I have a class that takes the
page instance being tested in the constructor (and the test class too)
and for each field annotated with @Inject it creates a strict mock and
sets the field to that value. It also adds the mock to an internal List
if mocks. Then the class provides convenience replay, reset, verify
methods that iterate over the whole list. The test class also has fields
that use a custom annotation (@Mock) these are injected with the same
values as those added to the page under test. So you end up with a test
class with populated mocks, a page class with populated services and a
helper class with the same mocks held in an iterable fashion for
convenience.

Subject: Re: T5: testing using PageTester and EasyMock

I was grappling with this issue myself, I still don't have a good answer
to
it. Because T5 is so heavily annotation driven (with the IoC and the
framework doing a lot of the magic heavy lifting behind the scenes),
testing
the pages as POJOs (e.g. setting some properties, performing an action,
inspecting the state of the page) is  not immediately obvious.

I've looked through some of the T5 unit tests (w/ EasyMock), and often
times
a page has a special (e.g. package private) method to inject services
that
otherwise the framework would inject. So, for example, if the page used
to
have an :

@Inject
FooService fooService

@Inject
BarService barService

Then, the page class would usually have a package private method like
this :


void setServices(FooService fs, BarService bs) {
   this.fooService = fs;
   this.barService = bs;
}

Anyway, there certainly is room for improvement, most advanced web
framework
have a way of testing pages/components as Pojos. Although the solution
above
works OK (and if you think about it, it's still pojos), it certainly
isn't
the first thing to think of once you get used to having Tapestry
injecting a
bunch of things into your pages. From a conceptual point of view, when
you're *unit *testing a page, you really DON'T want to have the "real"
services injected, and you'd probably just want to have
mocks/stubs/fakes in
their place that return the data needed to unit test the page. Now, if
you
were doing more of an "integration" type of test (e.g. where you test
how
the page works with the *real* service), then it's a different ball
game,
you do need the real services injected (for which you can still use the
above approach and not depend on the IoC to do it for you).

I guess the alternative would be to have a "test context" for binding
test/mock instances of the dependent services and somehow ask T5 to
inject
them into the page being tested. But then, it wouldn't really be unit
testing as the tests would depend on a whole bunch of things other than
the
unit being tested.

Let's keep this discussion rolling, we certainly need a little more info
on
testing in T5.

Alex Kotchnev

Hi Kristian,

hi lubor,

IMHO,  there is a much simpler and more elegant solution:

in order to save my data in a conversation state object i wrote
a decorator for the PersistentFieldManager intercepting every 
@Persist annotation if a conversaion is active.  And you can 
define an own persistence strategy @Persist("conversation") 
as well :)

I'm no native speaker but ApplicationStateObject is quite fine for 
me... it means to me, that there is one object somewhere (instance) 
that is the same in the whole application.

Re: T5: ApplicationStateObject is misleading






Hi Geoff,

I absolutely agree with you that concept of ASO objects and persistent
properties is one of few downsides of current Tapestry implementation. I
came across this type of problems recently when I was experimenting with
Tapestry & Spring Web Flow integration.

One of the issues that I had to solve was to find simple solution how
from
tapestry pages access objects stored in different webflow scopes. To 
achieve
this goal I couldn't use neither persistent properties nor ASO.
Persisted
properties can't be shared between different pages in the same flow and 
ASO
objects require additional configuration if you want to use non default
persistence strategy (to complicated solution). Therefore I was forced
to
develop my own solution which is based on my custom ScopeWorker that 
allows
page properties to be annotated by my custom @Scope annotation:

public class MyPage {

   @Scope(SESSION)
   private User user;

   @Scope(FLOW)
   private Facility facility;

   ...

}

@Scope annotation can be used with different scope types (APPLICATION,
SESSION, CONVERSATION, FLOW, FLASH, PAGE, REQUEST, etc.) to access
objects
stored in these scopes (when object is not found in the scope it's
automatically created).

I think that it would be good idea to find (in some future Tapestry 
release)
simple generic solution for scoping page properties that would replace
currently used ASO and Persist strategies (these could be marked as 
obsolete
and kept for backward compatibility reasons).

Regards
Lubor

Also, not to diminish the importance of the index; however, at this

RE: T5: Service disambiguation

[Russell Brown]

Thanks. That isn't what I originally implemented but it will do the job
just as well.

My problem is/was that SecureCookiesImpl uses the Cookies service as a
delegate (the constructor expects Cookies as a parameter) but doesn't
extend CookiesImpl...although it could. That would be one solution. I
wanted a SecureCookies service and a Cookies service, but the IoC sees
that as two Cookies services.

Like I said, I just de-OO'd it (no interface inheritance, no
relationship, SecureCookies is a separate unrelated interface and
SecureCookiesImpl is unrelated to and no longer delegates to Cookies and
I just inject *both* services) I would still like to know if this sort
of thing is possible. I think the autobinding of PersitantLocaleImpl is
the problem. Is there any way for me to disambiguate which Cookies
service it requires in its constructor? 

However this is an academic issue now since both of the solutions above
(mine and Filip's) satisfy my requirements.

You have to alias the Cookies service.

 binder.bind(SecureCookies.class, 
SecureCookiesImpl.class).withId("SecureCookies");
   }

   public static void 
contributeAliasOverrides(Configuration configuration,

SecureCookies extends Cookies, SecureCookiesImpl extends CookiesImpl and

implements SecureCookies.

I just tried it out and it worked for me on Tapestry 5.0.13.

Hope this helps.

Hi Thanks for the response.

What do I alias though? The PersistentLocaleImpl? I've tried creating an
alias for Cookies and SecureCookies. The problem is when TapestryModule
tries to build PersistentLocaleImpl it finds two Cookies interfaces
(SecureCookies that extends Cookies and Cookies itself (arguable that
they are the same  interface at all (I think not))).

I set it up with an alias for each of the offending services and a
builder for PersistenLocaleImpl that uses an @Marker to inject my
Cookies alias but the original TapestryModule still has problems
creating its PersistenLocaleImpl. Why is it even creating one if I have
contributed an alias?

What I have done is separated SecureCookies from Cookies. Just seems
simpler, though much less clean. So I lose some OO stuff, so what, eh?

RE: T5: Service disambiguation

[Russell Brown]

Hi Chris,
Do I? I'm not sure. Will that help the fact that PersistentLocalImpl has
a problem disambiguating between SecureCookies interface impl and
Cookies interface impl? I can add a marker to MY class that uses
SecureCookies but I can't add a marker to the TapestryModule auto binder
built PersistentLocaleImpl class (can I??)


Cheers

T5: Service disambiguation

[Russell Brown]

Hi,

I need to write secure session cookies and Tapestry Cookies interface
and CookiesImpl don't do that. So I extend the Cookies interface like
this

 

Public interface SecureCookies extends Cookies {

void writeSecureCookie(yada,yada);

}

 

And create an imple that injects the existing, TapestryModule created
CookiesImpl as a delegate and delegates all method calls to the existing
CookiesImpl and implements writeSecureCookie itself.

 

The problem is...the service PersistentLocale depends on Cookies and I
can't disambiguate that dependency.

 

The question why is SecureCookies the same interface as Cookies to
Tapestry IoC?

How do I go about creating a service that implements the same interface
as an existing tapestry service?

 

I'm a bit confused by all this. It seems that the safest way for me to
go is create a class that has no relationship to Cookies.

 

Russell

T5: Assets outside of the WebApp

[Russell Brown]

Hi,
I'm wondering if I can inject assets or better yet IncludeJavaScriptLibrary 
from outside the web app? For instance if I want to include the YUI libraries 
direct from Yahoo! rather than download and bundle them with my web app?

@IncludeJavaScriptLibrary( { 
"http://yui.yahooapis.com/2.5.2/build/yahoo/yahoo-min.js";,
"http://yui.yahooapis.com/2.5.2/build/event/event-min.js"; })

leads to:

Render queue error in SetupRender[AjaxIncluder]: Unknown prefix for asset path 
'http://yui.yahooapis.com/2.5.2/build/yahoo/yahoo-min.js'.

is there a prefix to say external: rather than context: of classpath: ?

Cheers

Russell

RE: Class not found exception

[Russell Brown]

I don't think run jetty run supports configuration by a jetty.xml. The
author says in his "Usage" instructions

"There aren't many options, just the web application directory, the
context and the port. I intentionally keep it basic so that it will be
easy to use and maintain; if you need anything more fancy, use one of
the other Eclipse app server plugins, or do what I often do: create a
start up class in your project."

Not sure where that leaves you. Sorry I can't be more help. The basic
problem is the same. You need to tell Jetty that you don't want it to
"hide" the slf4j server classes. One way of doing that is setting the
ServerClasses property as Ben did below. How you set that property with
run-jetty-run is beyond me. Sorry.

If you look at the wiki post linked to in my post you can just cut and
paste the code into a run class and you will be up and running very
quickly indeed. I agree with your "shoulds"...but maybe ditching
run-jetty-run would help.

Cheers

Russell

RE: [T5] Tapestry - Hibernate w/ multiple databases

Hmmm, create two tapestry apps that are modules/libraries rather than

the database?

Does that sound doable? Transaction demarcation could be interesting.

RE: T5: upgrade to T5.0.13 from T5.0.11 ClassNotFoundException for slf4j.Logger

That is it.

Russell,

I think this is a Jetty issue. Try running the application via mvn
jetty:run
- if this works then the problem is Jetty is hiding SLF4J from the
beanEditForm class loader.

What is happening is Jetty hides 'server' classes from the web
application
unless they are also in WEB-INF/lib. When you run in the IDE you don't
have
a WEB-INF/lib so it can't find the slf4j classes as they are loaded by
Jetty
as server classes.

You are starting Tapestry inside your IDE using a Run class - you need
to
add a line into your startup class saying

 // Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{"-org.mortbay.jetty.plus.jaas.", "org.mortbay.jetty."});



see http://wiki.apache.org/tapestry/Tapestry5RunViaMain for more
details.

Thanks

Ben

T5: upgrade to T5.0.13 from T5.0.11 ClassNotFoundException for slf4j.Logger

[Russell Brown]

Hi,

I have just upgraded my projects dependencies under maven from T5.0.11
to T5.0.13. Everything compiled OK (after I changed all the *.tapestry.*
imports to *.tapestry5.* imports and used the new refactored constants
classes). However when I request a page that includes a BeanEditForm I
get a large stack trace that seems to be caused by the following : -

 

Caused by: java.lang.ClassNotFoundException: org.slf4j.Logger

I had a look at the documentation of tapestry logging. I followed the
instructions here
http://tapestry.apache.org/tapestry5/tapestry-ioc/logging.html and added
the exclusions for log4j and added a dependency for logback (which we
use instead of log4j) (actually they were already in place, since this
worked fine in T5.0.11). And yet I get the problem above. I know this is
not specifically a Tapestry 5 issue but it is a new issue with T5.0.13
that was not present in T5.0.11 which worked fine with this
configuration. Any ideas anyone? Looking at the maven dependency tree
everything that needs to be there seems to be (logback, slf4j-apiare
there and log4j and slf4j-log4j12 are not)

 

Hope you can help,

 

Russell

library. I followed the Tapestry 5 book and the how to here

ary on the wiki. It is working ok for me so far except that one of my

*.*.*.pages package) it renedered correctly and the regexp for the

Can anyone let me know what I need to do to make this work? The
component is called register and the properties file is in the

 Well PageTester is definitely  in  Tapestry  Core - but  I had to  
include  tapestry  test module to get TapestryTestConstants - that was 
being used by PageTester - like your stacktrace so just add the tapestry 
test module.

These lines in PageTestContext seem to be the culprit

 public PageTesterContext(String contextRoot)
{
_contextRoot = new File(TapestryTestConstants.MODULE_BASE_DIR, 
contextRoot);
}

I looked in the jar and the svn repo and this class (TapestryTestConstants) is 
absent.

Any ideas?

RE: Service Configuration, ApplicationDefaults and String parameter in constructor

[Russell Brown]

Ok,
Sorry all. Scratch that. I RTFM. Here
http://tapestry.apache.org/tapestry5/tapestry-ioc/service.html#Injecting
%20Dependencies at the bottom of the page it says

" Every once and a while, you'll have a conflict between a resource type
and an object injection. For example, the following does not work as
expected:

It doesn't work because type String always gets the service id, as a
resource (as with the serviceId parameter). In order to get this to
work, we need to turn off the resource injection for the alertEmail
parameter. That's what the Inject annotation does:"

Sorry all

Subject: Service Configuration, ApplicationDefaults and String parameter
in constructor

Hi Again,

Now I have a Service that I want to configure with a string parameter
and an int parameter. I add a couple of values to the
ApplicationDefaults like this:

 

configuration.add("my.long.key.string-value",
"aStringINeedInMyService");

configuration.add("my.long.key.int-value", "180");

 

 

And in my service I have a constructor like this:

 

private final int intINeedInMyService;

private final String stringINeedInMyService;

 

 

public MyNewServiceImpl (@Value("${my.long.key.int-value
}")

final int cookieAgeInDays,
@Value("${my.long.key.string-value }")

final String cookieName) {

this. intINeedInMyService =
intINeedInMyService;

this. stringINeedInMyService =
stringINeedInMyService;

}

 

}

 

This seems to work except that the value of "stringINeedInMyService" is
always the Service's Service Id. I verified this by changing the Id of
the service in the AppModule by calling binder.bind(MyNewService.class,
MyNewServiceImpl.class).withId("MyDifferentId") and behold the value
injected into the String constructor parameter for the MyNewServiceImpl
was the new service Id. Is this expected behavior (IE have I miss
understood how to configure my service)? Or is there something else
going on? Has anyone configured a service this way before?

 

Many thanks

 

Russell

was the new service Id. Is this expected behavior (IE have I miss
understood how to configure my service)? Or is there something else
going on? Has anyone configured a service this way before?

 

Many thanks

 

Russell

Hi Russell,

I do this in the SetupRender phase.

@Inject
private org.apache.tapestry.services.Response _response;

void setupRender () throws Exception
{
if (/* condition satisfied */)
_response.sendRedirect( "http://example.com"; );
}

Cheers,
Bill

Redirects

[Russell Brown]

Hi All,

New to Tapestry 5. I have read the Building Web Apps Tapestry 5 book by
Alexander Kolesnikov and am working through the documentation and Wiki
too and I have a functional little web app at the moment that took me
all of a few hours to build and test so I am very pleased with the
productivity.

 

I haven't found how to redirect to an external url though. I think my
mind is stuck in Strruts MVC groove after all these years. So I have a
Page class and what I want the page to do is check for the presence of
an @ApplicationState property and redirect to an external url. In struts
I'd have the logic in the execute method of an Action. In Tapestry 5 do
I put this code in the onBeforeRender method? And how exactly do I do a
redirect to an external url please?

 

I know I am thinking in the action-forward-to-view way and that the
relationship between a page class and a page template is not exactly
analogous...I think this is conceptually where I am stuck. Not all web
apps are about pages so what metaphor is there for requests that aren't
page based? My practical problem above stems from current failure to
grok the pattern Tapestry 5 implements. 

 

Many thanks in advance if you can help (with either my practical or
conceptual problem).

 

Russell
