Re: Open Discussion: remove Bootstrap from T5 core

[Thiago H. de Paula Figueiredo]

Hello, everyone!

I know this thread is a bit old already, but Tapestry 5.5.0 can be used
without Bootstrap at all: https://tapestry.apache.org/release-notes-550.html
, https://tapestry.apache.org/css.html, @ImportModule(NoBootstrapModule.class).
In addition, there's a number of configuration symbols controlling which
CSS classes are output by the components which use Bootstrap ones by
default but can be overriden. If there's some CSS class still hardcoded,
please let us know.

Re: Open Discussion: remove Bootstrap from T5 core

[Ben Weidig]

Hi David,

we've used @extend with SASS in our projects and ended up not using it a
lot due to its drawbacks, instead we use Bootstraps mixins more directly.

I haven't read the article in its entirety, but here are my thoughts:

For decoupling the components it might be possible to wrap the needed CSS
in placeholder selectors and aggregate them it in custom shared classes and
load only what needed. But if the components don't use the Bootstrap
classes directly we would need to change 2 classes if we like to change
behavior (e.g. .form-control and .t5-form-control).

And this doesn't deal with changed HTML-structure of Bootstrap components
between version. We needed to adapt our TML multiple times between
Bootstrap 4.0.0 beta and 4.1.2 and 4.2.1 (especially custom controls stuff).

Separated JARs or component swaps might be the better or at least more
maintainable option IMO.

Nevertheless the direct integration of SASS-support would be great. As
written before we added it ourselves with the help of
https://github.com/bit3/jsass so we can build Bootsrap from its SASS-source
instead of using the CSS-only version, and we can add some SASS beforehand
to set the
https://github.com/twbs/bootstrap/blob/master/scss/_variables.scss before
compiling Bootstrap to customize it (thanks to !default).

Works without any major issues in our projects.

Ben

Re: Open Discussion: remove Bootstrap from T5 core

[David Taylor]

Anyone have experience working with the @extend directive in CSS 
preprocessors?


I came across a post that advocates decoupling HTML markup from 
bootstrap classes by using @extend. I don't particularly agree with many 
of the points the author makes, but the technique is intriguing and 
might be something that can applied to Tapestry since we support Less. 
Here is the link to the article.


https://hackernoon.com/the-backendification-of-frontend-development-62f218a773d4

The interesting bit is titled "Dealing with CSS Frameworks" and contains 
the following example:


%our-warning-button {
   @extend .btn;
   @extend .btn-warning;
}
.empty-shopping-cart-button {
  @extend %our-warning-button;
}

Searching the web a bit I came across another article that gets into 
this in more detail. The article's title is a bit misleading since it 
actually advocates the @extend technique and offer somes advice on best 
practices.

It is a while back, but was the tapestry bootstrap integration not
initially handled "externally" by a markup renderer filter (I guess it
removed the tapestry default styling and added the bootstrap equivalent).
Maybe something similar could be used to apply styling (Tapestry-BS3,
Tapestry- BS4 or whatever) to the tapestry components, without having to

Hi

I think working on making the framework "core" more css agnostic seems like
a good direction, allowing things to move forward without having to try and
pick (and maintain) the correct bootstrap version (or other css framework
version/flavor). There is a pretty good chance that whatever is selected,
will not fit the requirements of everybody anyway.

It is a while back, but was the tapestry bootstrap integration not
initially handled "externally" by a markup renderer filter (I guess it
removed the tapestry default styling and added the bootstrap equivalent).
Maybe something similar could be used to apply styling (Tapestry-BS3,
Tapestry- BS4 or whatever) to the tapestry components, without having to
dream up new stuff. (Provided that the processing does not become a
significant performance bottle-neck).

Thiago,

Template overriding would only work for those Tapestry-supplied components
that use templates, right? But most currently don't, which could be changed
and is part of what I was suggesting here:

I know it's not the most future-proven way of doing this, but couldn't a
simple solution would be to have a separate JAR which subclasses the
components using Bootstrap, do nothing but change the template and then
contribute the components to ComponentOverride?

Re: Open Discussion: remove Bootstrap from T5 core

[Numa Schmeder]

Sounds good! We would need to document bootstrap usage locations, and classes 
therefor we could use any library. We could also add default class names to all 
locations where there was bootstrap classes with tap- prefix.

Re: Re: Open Discussion: remove Bootstrap from T5 core

[Jens Breitenstein]

Thanks for you positive feedback. I suggest the following now:

1) I will use git hub to create a new T5 Fork based on Thiagos 
5.5.0-beta-1 and remove all bootstrap dependencies. As soon this 
compiles we will have a T5.5 version looking like websites in the good 
old early 80ies.


2) I will try to get our own (unfortunately internal) website up and 
running again, including the latest BS3, means all BS code is located in 
my client (it is anyway, because we use a newer BS3).


3) Next I extract all BS3 related code to a new module, thus we have a 
plain T5.5 without BS, a T5-BS3-extension and a sample APP using the BS3 
css classes / col definitions in TML code -> everything is like before, 
existing code should still run without modifications.




4) I invite you to discuss the implementation details how we can best 
make use of bootstrap related features without tight coupling so we can 
basically change between BS3 and BS4. This means we need some way to 
handle BS related differences like new / missing BS classes (for example 
panel) and we have to support the different grid definitions aso. One 
way (for example) might be T5 components to wrap most of the BS classes 
and each extension lib will take care of the particular BS details. At 
the very end our TML code never sees BS css classes at all, well at 
least for the "most common" things. We can start this discussion right 
now, because this is the tough part to my opinion. I would like to hear 
/ read all your ideas.


5) We / I create a mini App using the new T5-BSx extensions do 
demonstrate the use of the new BSx handling, we need it for testing / 
discussing anyway (see 4)



We move over our disussion to github to avoid polluting the mailing list.

Ok?

Hi Jens,

I like the idea of decoupling the core and Bootstrap to make it easier to
use other versions.

Maybe the components should be updated to BS4 for T5.5, with a legacy
fallback or a component swap (can't remember the service doing it, we have
our own implementation, it's doing an advice on
ComponentClassResolver#resolveComponentTypeToClassName or
ComponentInstantiatorSource#getInstantiator).

For 5.4 we've developed an internal solution for using different BS
versions, here are some specifics.

We have multi-tenant-apps with different BS versions (so far up to 3), so
we needed a flexible solution that supports the internal BS and other
versions dynamically.

To make it even more flexible we've added SASS-support and compile
Bootstrap from the source files, with the possibility to add files
beforehand to the compilation step with custom variables etc.

The layout component has an annotation that triggers
a ComponentClassTransformWorker2 attaching a JavaScriptStack containing the
BS version decided by a contributable strategy pipeline.

JavaScript modules were the biggest problems, we started with replacing the
internal modules, but ended up adding additional modules instead. This
worked fine after getting all the dependencies right, but every BS version
might break it again, so we're now using the bundled version of BS JS.

We think this could all be cleaned up nicely if the internal BS wouldn't be
as integrated as it is right now.

Eventually we will release it as open-source, but having an integration
into Tapestry (as a new tapestry-*) would be even nicer :-)

Best regards
Ben

Re: Open Discussion: remove Bootstrap from T5 core

[David Taylor]

I completely agree. We would like to move to bootstrap 4 and improve our 
integration with Kendo UI in the process.


We also need to upgrade bootstrap 3 to the latest version since there 
have been issues that cause it to show up as a XSS risk on application 
vulnerability scans. Just yesterday bootstrap 3.4.1 was released to 
address CVE-2019-8331.


We would be happy to participate in the development and testing of this 
feature. We are actively developing hybrid applications on Tapestry and 
would be able to test and provide feedback.

Hi Jens,

I am interested by your project. 
Maybe we can discuss further but right now I am super busy. What’s your 
strategy to injection css classes inside components ?

Re: Open Discussion: remove Bootstrap from T5 core

[Ben Weidig]

Hi Jens,

I like the idea of decoupling the core and Bootstrap to make it easier to
use other versions.

Maybe the components should be updated to BS4 for T5.5, with a legacy
fallback or a component swap (can't remember the service doing it, we have
our own implementation, it's doing an advice on
ComponentClassResolver#resolveComponentTypeToClassName or
ComponentInstantiatorSource#getInstantiator).

For 5.4 we've developed an internal solution for using different BS
versions, here are some specifics.

We have multi-tenant-apps with different BS versions (so far up to 3), so
we needed a flexible solution that supports the internal BS and other
versions dynamically.

To make it even more flexible we've added SASS-support and compile
Bootstrap from the source files, with the possibility to add files
beforehand to the compilation step with custom variables etc.

The layout component has an annotation that triggers
a ComponentClassTransformWorker2 attaching a JavaScriptStack containing the
BS version decided by a contributable strategy pipeline.

JavaScript modules were the biggest problems, we started with replacing the
internal modules, but ended up adding additional modules instead. This
worked fine after getting all the dependencies right, but every BS version
might break it again, so we're now using the bundled version of BS JS.

We think this could all be cleaned up nicely if the internal BS wouldn't be
as integrated as it is right now.

Eventually we will release it as open-source, but having an integration
into Tapestry (as a new tapestry-*) would be even nicer :-)

Best regards

Open Discussion: remove Bootstrap from T5 core

[Jens Breitenstein]

Hi Tapestry guys!

I want to hear/read your opinion about getting rid of the Bootstrap 
Library from T5 core.
I would like to move all BS related code (css/js) to a seperate module 
like "tapestry-bootstrap3" and decouple the hardcoded BS from T5.
Furthermore I would like to see a second module "tapestry-bootstrap4" 
which uses BS4.


From the sources I see direct dependencies are less than expected. Some 
tml's use it (I just ignore the internal T5 pages for now):


    AjaxFormLoop.tml
        class="btn btn-default btn-sm"
        

    BeanEditForm.tml
        class="btn-toolbar"
        class="btn-group"
        class="btn btn-primary"

    DevTool.tml
        
        class="dropdown-menu"
        class="dropdown-header"

    ExceptionDisplay.tml
        class="well"
        class="pull-right"
        class="checkbox"    // ?

T5 + Tynamo RESTEasy + UriInfo

[Michael Gentry]

This is an FYI in case it helps others.

Converting a non-T5 REST-based application into a T5 + Tynamo RESTEasy
version.  The original application used:

  @Context
  private UriInfo uriinfo;

to inject UriInfo to construct URLs to other REST services. but this
didin't work with Tynamo's RESTEasy.  You *can* add "@Context UriInfo
uriInfo" to your method's parameters, but that ended up kind of ugly
passing it around all over the place.  Since you couldn't @Inject the
UriInfo without some work, I came up with this to make it possible (add to
AppModule):

@Scope(ScopeConstants.PERTHREAD)
public static UriInfo build(HttpServletRequest request,
@Symbol(ResteasySymbols.MAPPING_PREFIX)
String restEasyPackage)
throws URISyntaxException
{
// Glue the container's context path to the T5 RESTEasy path so the
// URLs are constructed correctly.
String webServicePath = request.getContextPath() + restEasyPackage;

// Create the injectable and session-scoped UriInfo for this
request.
return new ResteasyUriInfo(request.getRequestURL().toString(),
request.getQueryString(), webServicePath);
}

With that added, you can put this in your web services implementation:

@Inject
private UriInfo uriInfo;

It works just like the @Context version, but is injected by T5.  Hopefully
that will save someone some effort in the future if they need this feature.

Re: some old criticisms of T5

[Cezary Biernacki]

In my experience Tapestry generates better HTML than many (most?) of other
frameworks. Lets take for example the whitespace issue. In most cases
whitespace in templates are artefacts of indentation used to improve
readability of templates during development. As the result when blindly
preserved, whitespace in generated HTML is just ton of unnecessary garbage.
E.g. it is not uncommon to see several empty lines at the start of
generated HTML from JSP-powered frameworks. Tapestry approach is much more
efficient.

Regarding, using a complain about problems with using Tapestry-generated
page as responses to AJAX calls, I believe that Tapestry offers better
solution with custom document builder dedicated for AJAX and returning a
custom structure. While just returning HTML snippets  for AJAX can work for
simple applications, it becomes maintainability nightmare for more complex
once: how to ensure that necessary CSS-es, JavaScripts are included but not
duplicated (and when pages are generated from multiple reusable components
that do not know about each other), how to insert the response into
multiple parts of the page, how to avoid DOM id conflicts, how to handle
errors in a friendly way. All of this is provided by Tapestry from the
start.

Another complain was problems with XHTML, thankfully it almost died.

Best regards,
Cezary

No, HLS replies were spot on. The only irritation I have found with T5 is
some of the default styling that gets added to handle form errors and these
can be overriden with your own css - can be mucky, but works.

Re: some old criticisms of T5

That's a very old article (2009 -- I don't think many users care about
IE6 redering quirks anymore), but Howard's comments there seem to do a
pretty good job of explaining where the author is either mistaken or
misunderstands the constraints and trade-offs involved. A lot of the
other commenters do likewise. I don't know if there is much more to

Tapestry 5 jobs, the value of learning to use T5 and transferable skills.

[Stephen Nutbrown]

Hi,

I feel this discussion belongs in the users group, although it is not all
directly related to Tapestry - it's related in some way or another and I
felt this community would be best positioned to talk about it. I have no
specific questions, this is intended more as a discussion/experience thread
(if that's allowed).

About 3 years ago, I began my first web project as part of my own work -
not for any company, just for some sites I needed to set up to support some
of my research. Perhaps naively, as a new user of Java EE (but experienced
with Java SE), I googled the net for "Simple to use java web frameworks"
and similar searches until I came across Tapestry. Some good reviews around
the internet and some good posts from Howard on SO lead me to running the
getting started tutorial and was amazed how easy it was - I was able to put
my Java SE knowledge straight into practise without knowing anything about
various xml files, or even the difference between a servlet, container and
application server, what CDI is or any of that. Everything was (and is)
running nicely on a jetty server. Whenever I became stuck, i'd go to the T5
documentation and read about how to use @Persist or @Sessionstate, or
perhaps how to work with services and injecting them or how to set up
Tapestry-hibernate - these kind of things (Or i'd ask here, and.. many
thank you's to the people of this mailing list for so much help).

Move on 3 years and I am fairly comfortable with Tapestry and have several
small projects (again, just for me, not a company or work). I then begin to
wonder if I've perhaps fallen into a trap of Tapestry5 being my golden
hammer - I see a web project, I think oh that would be easy using T5, my
favourite, and get started right away (Unless it requires CMS systems etc
in which case.. Joomla/Wordpress/Drupal). This is perhaps not efficient,
but fine until you begin a job search and use a big job site (monster.com)
and search the word "Tapestry5".

*"Sorry, no "tapestry5" jobs were found that match your criteria"*

Oh, I see. Well, that's not too bad - I see there are lots of companies
looking for java EE developers and in particular, (oddly to me), running
Wildfly stacks (formerly JBoss) and using RESTEasy etc.

These look entirely new to me, but then when you look a bit further you see
actually that @Inject is common (part of CDI and specified in JSR), session
beans (which I consider like session state) is a fairly normal concept, the
annotations for hibernate are of course all the same and actually..
Tapestry users are using a huge amount of the same set of tools, interfaces
and annotations as users of other stacks or frameworks. I see
@ApplicationScope and realise that it's a singleton, similar to if I added
it from a module and that I can then inject into pages. All very nice. At
this point I learn that actually whilst learning to use Tapestry5, mainly
through T5s documentation I have learnt an awful lot more - how to use
hibernate (and I learnt some elsewhere too), how to use maven, how to set
up jetty... how to inject things, what session state is and how things are
persisted.

I suppose my overall comment and question is.. how many of you work in jobs
where you use Tapestry5, and how many of you have tried to transition to T5
from a stack like wildfly, or from T5 to something like wildfly, and how
did you find it. How did you work on that transition? Why are there so very
few T5 jobs out there (In my limited opinion, hence the golden hammer, T5
is the best thing since sliced bread). I think perhaps one of my
missunderstandings is that I attribute many things which are actually part
of Java EE or other libraries/frameworks that T5 uses to T5 itself, without
realising that what I am actually working with is very common.

I wonder if anyone else has had similar experiences, or if anyone has any
advice for a Tapestry5 person who learnt effectively everything from the
documentation and mailing list to moving to other technologies.


Thanks, almost any discussion is welcome :).

Yes, that's certainly an option and that's how I've approached the
prototype, but this strategy doesn't work quite as well if you are
releasing to a customer as opposed to developing company's own site where
you typically already have an http server to deploy the Ember bits to. And
if you have to figure out packaging into a .war anyway, then might make
sense to use a similar setup for development as well. In any case, thanks
for the advice. I bet the framework has changed quite a bit in your two
years. I wonder if your experience has been a positive one and if there are
any "I wish I had known this before we started" tidbits you could share.

@Ivano - if popularity was a measure, we'd all be still using Struts
instead of Tapestry, wouldn't we? Convention over configuration is one
thing, but the article you linked to is a fairly well balanced in my
opinion. For me, the biggest things to like in Ember is it's router, clean
urls, cleaner/simpler concepts and performance.

Re: T5 and Ember

[Andreas Andreou]

Kalle,
After having worked for more almost 2 years on (mostly) ember,
my advice would be to completely decouple (if possible) the projects.

Move ember on its own, make use of the improving cli plugins for developing,
building and deploying. I'm still on a yeoman created grunt setup, so that
could
also work for you.

Just throw in some cors headers on the tapestry side and you'll be able to
live
code against production data

T5 and Ember

[Kalle Korhonen]

As an experiment, I'm trying to migrate an existing Angular app to Ember
(with T5 back-end and serving multiple other "thin" pages). There's a lot
to like in Ember vs Angular but I'm wondering if there are anybody else
using Ember with T5 and if so, what's your setup? I'm mainly interested in
knowing if you've managed to integrate wro4j's EmberJsProcessor or perhaps
you have just overlaid an ember-cli setup over T5 folder structure? Also,
I'd especially like to know how you handle third-party components if you
are using any. Installing snippets using npm and ember-cli seems like a
great idea but I find a lot of outdated and broken stuff. I'm using the
very latest, the ember-cli 0.2.1 released today (I was battling issues with
the previous 0.2.0 release over the weekend) and ember 1.10.0. Perhaps I'm
pushing too far on the bleeding edge... if you've gone done this path, I'd
appreciate some war stories for things to watch out for.

Re: Access a T5 app through both http (Tomcat) and https (Apache httpd + AJP + Tomcat)

[Martin Nagl]

Setting tapestry.secure-enabled to "false" and removing @Secure annotations
solved my problem.
Internal users can acces Tomcat directly via HTTP.
External users can access Apache httpd via HTTPS, which handles SSL and
forwards the request to Tomcat (via AJP).

Works nicely now when Tapestry does not redirect between http and https .

Thans for your advice.

Martin,

Have you tried setting the tapestry.secure-enabled symbol to "false" in
your AppModule.java? That prevents Tapestry from redirecting to https (and
you won't have to have @Secure annotations on your pages).

Re: Access a T5 app through both http (Tomcat) and https (Apache httpd + AJP + Tomcat)

[Norman Franke]

While not addressing your problem exactly, I have found issues with cookies 
doing things like this. You try to login via HTTPS. Your session is created as 
a secure cookie, and when you go back to regular HTTP after login, you have no 
session cookie. I created a new, non-secure cookie, but that’s definitely a 
hack and has some issues. I don’t use @Secure since I could never get anything 
working correctly, and so redirect myself.

You could try using something like nginx to do SSL to plan old tomcat running 
in HTTP mode. Using the @Secure annotation will still cause problems, since it 
will want to use HTTPS to / from tomcat. This would likely work, but local 
users won’t benefit from HTTPS for login. However, you could potentially us 
nginx to handle that as well, forcing HTTPS for a specific URL. 

You may be able to use your own MetaDataLocator service to determine that 
client IP address and decide there. Obviously if you are doing a reverse proxy, 
the Http Request IP address won’t necessarily be the client’s IP address, but 
most proxies add a header you could use.

Re: Access a T5 app through both http (Tomcat) and https (Apache httpd + AJP + Tomcat)

[Martin Nagl]

Aha, sorry for the "hardcoded" part, I can see that the number 80 is only
used to determine whether to include port in URL or not :) Will try to
provide HOSTPORT instead.

Re: Access a T5 app through both http (Tomcat) and https (Apache httpd + AJP + Tomcat)

[Martin Nagl]

I am using Tapestry 5.3.6.

I have not overridden BaseURLSource or anything simmilar.
I have not provided HOSTPORT or HOSTPORT_SECURE.

Looking at the code in BaseURLSourceImpl, maybe my problem is that http
communication goes on port 8080, not 80 as expected (hardcoded in
BaseURLSourceImpl). I will try to experiment more with the settings above
and figure out how to test it on my local machine.

Re: Access a T5 app through both http (Tomcat) and https (Apache httpd + AJP + Tomcat)

[Jonathan Barker]

I've faced similar issues in the past (see TAP5-167), but these days I
just access everything through https.

It does sound like you were using @Secure on your login page, but
nowhere else.  I seem to recall that if you use @Secure on one page,
then it will try to use http on pages NOT marked with @Secure.  To get
around that, you end up skipping the @Secure and sending passwords
plaintext over your internal network - not a great practice.

I am curious if anyone ever came up with a good way of doing what you
are trying to do.

A few questions that come to mind are:
Which version of T5?
Have you overridden anything like BaseURLSource?
Have you provided any parameters like HOSTPORT or HOSTPORT_SECURE?

Access a T5 app through both http (Tomcat) and https (Apache httpd + AJP + Tomcat)

[Martin Nagl]

Hi all,

we have a Tapesty5 application deployed on Tomcat + Apache httpd. In
production environment at our customer, the application should be deployed
/ accessed like this:
  - Tomcat is running on a server in internal network on port 8080.
  - There is an Apache HTTP server with reverse proxy to Tomcat (AJP)
accessible from the internet on port 80.
  - Internal users should access the application on Tomcat directly without
https on http://servername.intranet.customer.sk:8080/appname/login
  - External users should access the application through Apache httpd, with
https, on https://apps.customer.sk/appname/login

1. Initiallly, I had no @Secure annotations on my pages. The application
worked correctly from internal network, but not from internet. From
internet, I could access the login page through https, but after submit, I
get somehow redirected to http which ends with server error: Your browser
sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

2. I have annotated all my pages with @Secure. The aplication now works
correctly from internet, but not from internal network. From internal
network, I can access
http://servername.intranet.customer.sk:8080/appname/login but I get
redirected to https at
https://servername.intranet.customer.sk:8080/appname/login. - This is not
desired, I would like the application to continue in http mode.

Is this setup possible with a Tapestry5 application (a single deployed
instance)?
Is there some way to tell Tapestry "If you're accessed through https, then
serve all pages through https, else if you're accessed through http, then
serve all pages through http"?

Thanks
Regards
Martin

Re: requireJS modules in T5 library

[Geoff Callender]

Your module is not returning anything and init is invisible outside the 
module's function. After the init function add this...

return {
init : init
};

The rest looks fine, assuming that you've checked that threedots is AMD 
compliant. if it isn't then you'll have to shim it (search the mailing list for 
contributeModuleManager).

Cheers,
Geoff

requireJS modules in T5 library

[Jan Fryblik]

Hello guys,

I'm fighting a bit with RequireJS modules. So...

I have Tapestry library 'cms' with 'LastArticle' component. So I have  
simple RequireJS module in

resources/META-INF/modules/cms folder with following code

define(["jquery", "t5/core/dom", "jquery/jquery.threedots.min"], function  
($, dom)

{
init = function (rowsCount)
{
$('.preview').ThreeDots({ max_rows: rowsCount });
}
});

and in LastArticle.java I call:

scriptSupport.require("LastArticle").invoke("init").with(previewLinesCount);

in SetupRender method.

In javascript console then I can see error "TypeError: moduleLib is  
undefined". So either I still don't fully understand this concept or I've  
missed something. Could you please help me? Thanks a lot in advance!


Best,
Jan

If you had mentioned before you were trying to show it in a Zone update, we 
would have understood the problem earlier. You can use blocks in non-AJAX 
scenarios too.

In your case, using your own code, not the one from tapestry5-jquery, the check 
for whether the Google Maps is already loaded should be part of your own code. 
Not a good solution.

Ultimately the solution is to use Require.js or a similar solution and let it 
handle the client-side dependencies and ensure the loading order of JavaScript 
files. Tapestry 5.4 supports it out-of-the-box.

Hi Thiago

Yeap, to simplify the problem, the tapestry5-jquery's GMap component has the 
same problem, with the next code the component renders correctly the google map.

Test.tml

Test.java
public class Test  {
public JSONObject getOptions(){
JSONObject json = new JSONObject();
return json;
}
}

With the next code the GMap component does not render correctly the map after 
you click the refresh link (to show the block).

Test2.tml:
refresh





Test2.java:
public class Test2 {

@Inject
private Block blockResults;

Object onActionFromRefresh() {
return blockResults;
}

public JSONObject getOptions(){
JSONObject json = new JSONObject();
return json;
}
}

When you press refresh link the browser (Chrome) javascript console error is: 
"Failed to execute 'write' on 'Document': It isn't possible to write into a 
document from an asynchronously-loaded external script unless it is explicitly 
opened."


Reference:

This way (which I suggested, I'm sorry), with the external library included in 
setupRender() and your code that uses it included via @Import, the two JS files 
are included in the wrong order, because @Import is processed before 
setupRender(). Please try this:

@Inject
@Path("classpath:mx/kka/msurvey/web/view/components/maps/googlemaps.js")
private Asset myCode;

public void setupRender() {

javaScriptSupport.importJavaScriptLibrary("https://maps.googleapis.com/maps/api/js?v=3.exp";);
javaScriptSupport.importJavaScriptLibrary(myCode);
)

This will guarantee your code will be included after the Google Maps API.

The component being inside a block (you mean ?) shouldn't make a

Hi Thiago, thank you for your answer :)
I'm using Tapestry 5.3.7

> Where's your JavaScript?
For google maps, you have to access the javascript library from a URL, so my 
javascript is inside the url: "https://maps.googleapis.com/maps/api/js?v=3.exp";

> How are you including it?

public class GMapShow {
@Inject
private JavaScriptSupport javaScriptSupport;

public void setupRender() {

javaScriptSupport.importJavaScriptLibrary("https://maps.googleapis.com/maps/api/js?v=3.exp";);
}
}

> If you put your JavaScript code inside a .js file and included using @Import

Testing it, I have created a file (googlemaps.js) with the content of the url: 
"https://maps.googleapis.com/maps/api/js?v=3.exp"; and included it inside 
component:
@Import(library = 
"classpath:mx/kka/msurvey/web/view/components/maps/googlemaps.js")
public class GMapShow {
}

But the result is the same, the map is rendered correctly if the component is 
outside a block but if the component is inside a block, the map is not renderer.

I suppose the javascript inside 
"https://maps.googleapis.com/maps/api/js?v=3.exp"; is loading another javascript 
files and maybe the component is rendered before all all javascript libraries 
are loaded. 
The javascript has snipets that looks like:

getScript("https://maps.gstatic.com/maps-api-v3/api/js/18/5/intl/es_ALL/main.js";);
apiLoad([0.00999776482582,[[["https://mts0.googleapis.com/vt?lyrs=m@27500\u0026src=api\u0026hl=es-ES\u0026","https://mts1.googleapis.com

Re: [T5] How can I validate if a script is present ?

Hi Thiago
Ok, I will more specific:


Hi!

Thanks for being more specific. :) We want to help, but it's quite hard

 I'm developing a Tapestry component (GMapShow) that renders a google  
map. If I include the google maps javascript library directly in this  
component, the map is not render if the component is inside a block, so  
I need to include the library BEFORE the block (with the GMapShow  
component) is rendered.


So, I have created a component to only include the Google Maps library:
public class ImportGMapLib {

@Inject
private JavaScriptSupport javaScriptSupport;

public void beginRender() {

javaScriptSupport.importJavaScriptLibrary("https://maps.googleapis.com/maps/api/js?v=3.exp";);
}
}


By the way, from T5.4 on, you can use https://, http:// and //: in @Import.

Where's your JavaScript? How are you including it? That's probably the  
source of your problem.
If you put your JavaScript code inside a .js file and included using  
@Import or JavaScriptSupport.importJavaScriptLibrary(), your code would be  
automatically included after the library you're using.


That's why we ask people more information and snippets of code when asking  
help: the original question in the subject of the message (how can I  
validate if a script is present), which, by the way, is  
JavaScript-specific, not Tapestry-specific, wouldn't need to be asked.

You cannot. Component instances need to be declared inside a template.  
Tapestry templates are strictly static in structure, even having completely 
dynamic behavior, and what you're asking needs dynamic structure. Static 
structure allows Tapestry to be very fast and use less memory at the same time.

In a higher level, what you're trying to do? Without the answer, I can suggest 
you creating the template and using the If component:

In your Java class:

[T5.4] Does exanpe-t5-lib work with Tapestry 5.4 ?

[D Tim Cummings]

I am using exanpe-t5-lib to include some google maps on a page in Tapestry 5.3 
and want to upgrade my app to 5.4.  

exanpe-t5-lib version 1.3.0-SNAPSHOT from the master branch caused problems 
starting my app so I have checked out branch br_5.4 from github 
exanpe/exanpe-t5-lib (version 2.0.0-SNAPSHOT). Now when my app renders the page 
containing the google map it doesn't include all the javascript files. I have 
added yahoo-dom-event.js because it was missing some YAHOO features. Now I get 
a javascript error


RequireJS error: require: google.maps.InfoWindow is not a constructor

Re: Peformance loading huge data with T5 grid.

[Howard Lewis Ship]

The key to performance with Grid is to look to the GridDataModel and
provide a smarter caching version that limits the amount of data taken from
the database.

That being said, Grid is an scaffolding component ... much like
BeanEditForm. It is meant to be useful but if a grid view of some form is
essential in your application, you will benefit by building something
simpler and custom to your application.

Re: Peformance loading huge data with T5 grid.

[A.T. van Kalleveen]

Hello Duy,

Have a look at the weaves Tapestry 5.x library, it contains a Pagedgrid 
component with a custom gridsource which will never query the total number 
of rows in a dataset and uses paging to increase performance, especially for 
large datasets. We use it to scroll through recordssets of over 1 million 
records.


The code is here: https://github.com/intercommit/Weaves

A demo is here: http://intercommitweavesdemo.intercommit.cloudbees.net/

Re: T5 Tynamo RestEasy, discovering all rest resources and paths

Hi Daniel

Take a look at RESTEasy's JSAPIWriter [1] and how it was integrated
with tapestry-resteasy [2]
I think you will find everything you need in there.

If you need even more discoverability than that I'd recommend to use
something like Swagger [3]

T5 Tynamo RestEasy, discovering all rest resources and paths

[Daniel Jue]

Hi,  I have a bunch of rest services, across a couple modules.  One of the
rest services is a meta type of service, where the methods (via
parameter-less @Get requests) return things like canonical values/enums
used as query values elsewhere in the system.


Anyway, some member(s) of our team like to change the rest paths around and
this breaks the JS front end of course.

Is there a way to collect:

1) The rest services paths for each service (i.e. the @Path value on the
class)
2) The individual resources' paths (i.e. the @Path on the methods)

Oh and I guess knowing the root rest path as defined in your module would
be nice too.


If I had the complete or relative paths to the individual methods, that
would solve my problem 100%.

The plan is to then expose the available paths through a method under the
meta rest service.

It's not really HATEOAS, I just want to keep the JS guys and back end guys
from stabbing each other (myself included)

Re: T5 IOC Integration Questions

[Martin Kersten]

Norman, I implemented something I called Invoker lately. It was quite easy
to do field injection and calling methods where you inject all parameters.
The mixed part was quite difficult though (provide some parameters and
inject the others). Also be aware of that the ordering of methods is not
guaranteed in any way using JDK 7 192 and above (getDeclaredMethods and
getMethods along with getConstructors now return methods in random order).
I fixed the issue by using ASM and visit each method in the order they are
stored within the class file (which is the exact order you define it in the
java file).

So beside this if you are doing invocation and injection on fields and
methods go ahead. This wont take more then an hour at most. If you need
additional help, just ask. You can even invoke and create private classes /
constructors and methods which comes quite handy in case of writing test
cases.


Cheers,

Martin (Kersten)

Unless there's some setter we could call through injection, I don't think

Most IoC features can only be implemented because the IoC container is

T5 IOC Integration Questions

[Norman Franke]

I'm trying to better integrate Atmosphere and Tapestry 5. It would make life 
easier if there was a way for T5's IOC layer to inject into an existing object, 
instead of having it need to create objects itself. I can't find one, if it 
exists.

I have made a few modifications to Atmosphere that let me use the Tapestry IOC 
layer to create most objects, which allows me to use @Inject to gain access to 
my services from classes Atmosphere instantiates to process requests. I'd like 
to have a more complete solution where the Tapestry IOC layer can know about 
the AtmosphereFrameowrk and AtmosphereConfig and inject them as well.

Any thoughts?

Re: [5.4.22] Application 'randomly' starts choking out 404s for t5/core/dom and underscore

[Peter Hvass]

Yes have managed to get 404s by interrupting a page load.. guess it makes 
sense. But it doesn't reoccur 
for subsequent attempts whereas in the issue we're experiencing it does. Plus 
the 404s generated by interrupting 
page load are occurring regardless of GZIP being on or off (which again stands 
to reason I guess - just for verbosity). 


Will try running with GZIP off in any case and see if our issue reoccurs.

Thanks for the reply Howard; we'll run with GZIP disabled for a while and see 
if it reoccurs. 


So reloading page while modules are still loading up might reproduce perhaps? 
Will give it a go!

You can also test your theory by disabling GZIP compression.

Re: [5.4.22] Application 'randomly' starts choking out 404s for t5/core/dom and underscore

[Peter Hvass]

Thanks for the reply Howard; we'll run with GZIP disabled for a while and see 
if it reoccurs. 


So reloading page while modules are still loading up might reproduce perhaps? 
Will give it a go! 


We're noticing that when this starts happening it starts happening for every 
single session. :P 


Will try to find out more!

[Howard Lewis Ship]

Does this only occur during testing?  I've found that we sometimes see this
during testing when Selenium starts loading a new page while there are
outstanding AMD module requests; the requests fail as if 404 just before
the new page content loads.

[5.4.22] Application 'randomly' starts choking out 404s for t5/core/dom and underscore

[Peter Hvass]

Hello, 


Having a hard time reliably reproducing this one, wondering if anyone else has 
run into similar; 


We start getting the following in our browser consoles; 

GET http://sadaharu:8087/village/asset.gz/module/t5/core/dom.js 404 
(/asset.gz/module/t5/core/dom.js) require-2.1.8.js:1880 
GET http://sadaharu:8087/village/asset.gz/module/underscore.js 404 
(/asset.gz/module/underscore.js) require-2.1.8.js:1880 
Uncaught Error: Script error for: t5/core/dom 
http://requirejs.org/docs/errors.html#scripterror require-2.1.8.js:163 
Uncaught Error: Script error for: underscore 
http://requirejs.org/docs/errors.html#scripterror require-2.1.8.js:163 


A restart or reload (via new exception pages) fixes it. Have compared network 
info, mark-up and such locally between a working run and a broken run and all 
is identical. 


Am wondering if Tapestry is choking on what it provides in assets.gz from time 
to time. 


Will reply if I learn anything that will allow me to be more specific but in 
the meantime would be good to hear if anyone 
else has run into this issue. 


Thanks,

What you actually want is to execute JavaScript when an AJAX call is  
finished. If it's a zone update, here's the solution:

T5: bind onlick handler after LinkSubmit

[Dmitriy Vsekhvalnov]

Hi all,

i'm looking for a way to bind event handler (js) to  element which also
is LinkSubmit, but i'd like my event handler to be executed after
LinkSubmit handler.

E.g. consider example, form inside modal dialog - make ajax call to server
first, then close modal.

Ideas?

You probably want to wait for Java 8 and its first class functions aka  
functional interfaces and lambdas. :) A nice description of that and other  
Java 8 improvements are here:  
http://www.techempower.com/blog/2013/03/26/everything-about-java-8/. I  
can't wait for them.


By the way, even if your future project is independent from T-IoC, T-IoC  
could integrate it, just like it does with Plastic. :)

Re: [OT] T5-IoC in Fantom

[Howard Lewis Ship]

I have some ideas for a next-generation IoC that I hope to put together
someday (outside of Tapestry).  I want to create something with a different
level of granularity, were you are injecting functions, not services. There
would be a whole lot of generics gymnastics to figure out how to map from a
generic function interface to a static or instance method of a class that
is exposed for injection, with lots of annotations to be used to
disambiguate. Unfortunately, this is pretty far down my list of things to
work on!

Of course there is! Any module from any pod (jar) can contribute to
services defined in any other module from any other pod. That is
distributed configuration, right? That was built in from the get go!

> Well, I hope you had a chance to address some of the things that are not
perfect in T5 IoC!

I addressed a few (of what I felt were) shortcomings, tidied up the API a
little, and tried to keep the API to 'core' functionality. A couple of
subtle differences include:

 - configuration overrides may themselves be overridden
 - ctor params may be passed into Registry.autobuild()
 - emphasis on annotations (facets) and not naming conventions

I learnt a lot from the project and now certainly appreciate the recursive
complexity involved in maintaining an IoC registry!

Cheers,

Steve.

[OT] T5-IoC in Fantom

[Steve Eynon]

Hello,

If imitation is the sincerest form of flattery then T5-IoC has been paid a
huge compliment...

...there's an IoC in the language Fantom that bears a striking resemblance
to T5-IoC!

afIoc - http://repo.status302.com/doc/afIoc/#overview

I've been an avid fan of Tapestry since v3, and with the advent of T5 I've
learnt to adore T5-IoC - the foundation of all my apps (both desktop and
web). So much so, as I'm now (slowly) moving away from Java, I couldn't
bear to leave it behind.

As my new language of choice, Fantom http://fantom.org/ , didn't have an
IoC, I took it upon myself to implement one in the image of T5-IoC,
bringing with it all the goodness T5-IoC provides!

I realise this post is slightly off topic, but I wanted to give
acknowledgement and thanks to all those inspiring T5-IoC developers, your
ideas are awesome! So, err, thanks!

Um, I'll get my coat...

Steve.

Oh, for those who don't know Fantom, a reasonable quick overview is given

Yes. I'm already using freemarker. Just want to use less dependencies

I started to extract the logic to a separate project here
https://github.com/uklance/tapestry-offline but never got around to testing
it.

The main functionality is in this class
https://github.com/uklance/tapestry-offline/blob/master/src/main/java/org/lazan/t5/offline/services/internal/OfflineComponentRendererImpl.java

Let me know if it's useful, pull requests welcome :)

Re: [t5] Is it possible to return a component's generated HTML ?

[Muhammad Gelbana]

I strongly believe that Dmitry's suggestion is the simplest and most
efficient so far, thanks a lot for that :)

This would send an ajax request acceptable by tapestry:
ajax = new XMLHttpRequest();
ajax.open("POST", "http://localhost:8080/index:myevent/0/0/0";, true);
ajax.setRequestHeader("X-Requested-With", "XMLHttpRequest"); //This is
necessary
ajax.send(null);

Thank you all :)

Re: [t5] Is it possible to return a component's generated HTML ?

[Dmitry Gusev]

If you only need to get HTML on the client and not on the server-side,
then you may just use Tapestry's built-in logic for handling AJAX requests.

On the server side create eventLink:

Link link = resources.createEventLink(eventType, contextValues);
return link.toAbsoluteURI();

Pass this link to client side during rendering and when needed do the AJAX
calls using, say, jQuery.ajax.

You may handle ajax request on the server side the same way I wrote in my
example above --
return block from event handler or use ajaxResponseRenderer.addRender().
On the client-side response will be the same JSON and you may extract
content from it.

Note that in both cases it is possible to render multiple blocks by one
request -- this is if you call
ajaxResponseRenderer.addRender() multiple times.

Actually Lance's second approach is what I need to do. And yes it should be

Re: [t5] Is it possible to return a component's generated HTML ?

[Dmitry Gusev]

The entry point is:

String rawAddress = renderer.render(new RenderEvent(
"internal/companyblocks", "companyAddress", company));


You tell here that onCompanyAddress method (or method with
@Event("companyAddress")) should be invoked on the internal/companyblocks page
class and if that method returns a Block - it will be rendered to a string.
company - is a parameter to that method that you may use to initialize
rendering context for the block.
You can also not return Block from the method by just addRenderer:

ajaxResponseRenderer.addRender(addressBlockZone);

And the addressBlockZone will be rendered to as string in this case.

Resulting string will be serialized json object, so you can inspect its
structure and take the content you want like:

String htmlAddress = new JSONObject(rawAddress).getString("content");

Re: [t5] Is it possible to return a component's generated HTML ?

[Lance Java]

I think I need to understand how it's going to work before I go any further.



Here's one approach

1. The browser makes a request to the "other" webapp

2. The other webapp makes request(s) to the tapestry app

3. The other webapp merges it's own html with the tapestry html to create a
page

4. The page is returned to the user



Here's another approach

1. The browser makes a request to the "other" webapp

2. The other webapp returns a page with some empty divs

3. Some javascript runs on page load

4. The browser makes requests to the tapestry app

5. The tapestry app returns responses to the browser

6. Some javascript in the browser updates the innerHTML of some div's



In both approaches, you are going to be fighting an uphill battle if you
want to handle javascript and eventlink / actionlinks in your tapestry
components. If you simply want to render html fragments, without links or
javascript we might be able to help.

Re: [t5] Is it possible to return a component's generated HTML ?

[Muhammad Gelbana]

Honestly, I can't figure out anything from these 2 resources ! It all looks
so complicated to me.

@Dmitry
What is the entry point of your code ? When an ajaxrequest is sent to my
application, doesn't it reach your "CompanyBlocks" page ? Then when does
all the other services begin working ?!

@Lanve
And I thought Dimitry's code was complicated :D
Your code was even harder to look at, I also can't understand the entry
point and the flow of data starting when I receive an ajax request till I
respond with a string representation of a component's template file.

Thank you all for your help :)

[Lance Java]

I'm not 100% sure what your implementation will be but I've done some work
in this area.

Take a look at PDFLink.getFoAsString() where I convert a RenderCommand to a
String of markup (XML in the example)

You can put your component to a block and render this block.

[t5] Is it possible to return a component's generated HTML ?

[Muhammad Gelbana]

Hopefully I'll explain this clearly.

I'm willing to integrate my tapestry web application with another web
application. That other web application will request ajax urls from my
application.

In my application should reply in HTML. So it would be much easier to be
able to use the regular tapestry component\page tml to construct the HTML
response. So that I can easily bind the tml to my component\page and let
tapestry do it's magic on generating the HTML.

Is this possible in tapestry ?
