RE: Jetbrains considers to deprecate Tapestry plugin in IntelliJ 2019.3

[Svein-Erik Løken]

I have built front-ends with Typescript,  JSX,  React, sometimes mixed with 
Tapestry Zones. I always tries use T5 components, but not too hard. The admin 
client don't need to be so fancy and is 95% Tapestry code. I found that the 
quality and code maintaining is much better when using Tapestry. For me 
Tapestry is almost perfect, but of course I hope the framework will evolve.

I am a huge fan of IntelliJ Ultimate. If the Tapestry plugin stops to work then 
don't know what to do! I think it is absolutely necessary for coding speed, 
navigating and quality check. 

I hope that having the IntelliJ Tapestry plugin open source then it can be even 
better. I have reported several issues to JetBrains, but they are still 
unresolved. The most important now is that the plugin will work in new versions 
of IntelliJ.

Again, a big thank to the guys that keeps Tapestry going.

React repeats the same sins as JSP by mixing code and presentation. A problem 
tapestry addressed. Its kind of strange seeing this JSP age issue afflict those 
“better frameworks”.

I’d also wager a SPA could be developed more quickly in tapestry than with any 
JS framework plus an API. Then there there’s also the fact that tapestry apps 
can be developed by any Java developer without a need for much additional JS 
expertise.

Can’t really compare apples and oranges.

RE: How to let the last ajaxResponseRenderer win?

[Svein-Erik Løken]

I have tried several methods without luck, but found a solution now. I don't 
want to rewrite the Tapestry javascript code if I don't have to, but found a 
way by stopping propagation of the events.zone.update. I have a filter on a 
grid. The grid is big and when Tapestry calls $.append(content) to insert zone 
data the browser gets very laggy. By including the input value in the zone, 
then I can check on match with the current user input when zone is ready to 
update. The mixin accept multiple zones.

I tried http://jumpstart.doublenegative.com.au/jumpstart/examples/ajax/onevent, 
but I does not sync data and will display wrong result (om large zone updates).

Debugging:

STOP: stopPropagation
UPDT: Let zone update be handled as default
Test on currentInputVal vs inputValInZone

STOP: tes !== t zone:destinationTableZone
STOP: tes !== t zone:destinationCountZone

The code:
mixins\ZoneSync.java: 
public class ZoneSync {
@Parameter(required = true, allowNull = false)
Object[] zones;

void afterRender() {
String zonesSelector = Arrays.stream(this.zones).map(zone -> "#" + 
((Zone) zone).getClientId()).collect(Collectors.joining(","));

javaScriptSupport.require("mixins/zone-sync").invoke("syncWithInput").with("#"

Hi,

A server-side solution will not solve the problem, as responses from the server 
can be re-ordered because of network transmission hick-ups. With Tapestry, you 
can the abort Ajax requests on client-side as well, it uses Jquery (or 
Prototype.js) under the hood.  I would monkey-patch dom.ajaxRequest function 
(see t5-core-dom-jquery.js or t5-core-dom-prototype.js depending if your are 
using Jquery or Prototype), to track currently running AJAX requests and abort 
it if a new one is issued using Jquery's or XMLHttpRequest's abort methods. A 
more advanced solution would allow multiple requests and only abort ones that 
are conflicting with each other.

How to let the last ajaxResponseRenderer win?

[Svein-Erik Løken]

When typing "test" pretty fast into textfield id=nameFilter the result is 
wrong. I am typical getting "DEBUG nameFilter: te" (sometimes just "t"). The 
grid data corresponds to the nameFilter output.

The output from  getNamefilterDebug() is always:
getNamefilterDebug: t
getNamefilterDebug: te
getNamefilterDebug: tes
getNamefilterDebug: test




Name:

${destinationBeans.size()}



DEBUG nameFilter: ${namefilterDebug}




void onSubmitFromNameFilterForm() {
applyFilter();
ajaxResponseRenderer.addRender(destinationTableZone);
}


public String getNamefilterDebug() {
System.err.format("getNamefilterDebug: %s%n",nameFilter);
return nameFilter;
}


When using JavaScript/React I just call XMLHttpRequest.abort() for all ongoing 
XHR's.


I cannot figure out how to do this in Tapestry 5.4.4. I was looking for 
AjaxResponseRenderer addRender(ClientBodyElement zone, abortPrevious);

RE: Browser History API

[Svein-Erik Løken]

On history back (back button I browser) an old page can be used (included 
outdated cookies).

I am using Tapestry templates if it fills my needs. The code gets more robust 
that way. On more complicated UX parts when state changes and fields need to be 
updated React is very nice. When Tapestry Zones gets to complicated I switch to 
React, or mix them.

The communication with Tapestry is done using ajax or forms. A snippet using 
Tapestry form:

   let $hiddenAirTemp = $("[data-id='hiddenAirTemp']");
let $waxDataForm = $(waxDataFormSelector);
WaxEndUser.stopCallback = (y: number) => {
$hiddenAirTemp.val(WaxEndUser.airTemp);
$waxDataForm.submit();
};

I use Tapestry Ajax to get good error messages:

   writeCookies() {
let options: MapUserSettings = {
focusSkateTrail: this.focusSkateTrail
};
TapestryUtil.ajax("/index" + ":writeMapUserSettingsCookies", {data: 
options});
};

tapestryutil.ts:
...
/*
 * @public
 * @param {string} url
 * @param {Object=} options
 * @param {{}|String|Array} [options.data]
 * @param {String} [options.method=POST]
 * @param {TapestryUtil.ResponseFunction} [options.success]
 * @param {TapestryUtil.ResponseFunction} [options.failure]
 * @param {Function} [options.complete]
 * @returns TapestryUtil.RequestWrapper
 */
static ajax(url: string, options?: AjaxOptions): RequestWrapper {
let newOptions = {...options};
return Ajax(url, newOptions);
};


I think TypeScript is a "must" to get good client code. I use also JSX. I am 
looking for a way to use the same interface for Tapstery/Java services and 
Typescript for data access. Maybe Kotlin can be used.

RE: QuickStart

[Svein-Erik Løken]

I think Tapestry is super for small to medium projects. Tapestry has bundled 
JQuery, datatable, boostrap, underscore etc. It comes with a lot of nice usable 
Tapestry components. Tapestry takes care of making everything working together, 
but you can use your own version of e.g. JQuery if you want. Tapestry is very 
customable. Live class reloading makes the development superfast. For easy UX I 
am using plain Tapestry templates. For more advanced applications (single page) 
I am using some React/JSX. Some elements in the page are still Tapestry Zones 
because they easy to use. Tapestry works nice as a service layer for serving 
data to my JavaScript when needed.

I think Spring is for large projects.

RE: Javacsript module problem

[Svein-Erik Løken]

Take a look at the page source in the browser. Tapestry 5.4 loads modules at 
the end of the page.

A sample of the tapestry way (what I know) to load shim:
In AppModule.java
@Contribute(ModuleManager.class)
public static void setupMyBaseModules(MappedConfiguration 
configuration,
  
@Path("META-INF/assets/jacillacore/highcharts/highcharts.src.js") Resource 
highchartsSrc,
  
@Path("META-INF/assets/jacillacore/highcharts/highcharts-more.src.js") Resource 
highchartsMoreSrc) {
configuration.add("highcharts", new 
JavaScriptModuleConfiguration(highchartsSrc));
configuration.add("highchartsMore", new 
JavaScriptModuleConfiguration(highchartsMoreSrc).dependsOn("highcharts"));
}

I would recommend to use AMD modules instead of inline javascript.

RE: Contribute requirejs.config.paths to ModuleManager

[Svein-Erik Løken]

I tried to fight it too, but had to capitulate. 

After some debugging my @Contribute(JavaScriptStackSource.class) was not set:

public class ModuleManagerImpl implements ModuleManager
{
private Resource resolveModuleNameToResource(String moduleName)
{
Resource resource = shimModuleNameToResource.get(moduleName);

if (resource != null)
{
return resource;
}

// Tack on a fake extension; otherwise modules whose name includes a 
'.' get mangled
// by Resource.withExtension().
String baseName = String.format("/META-INF/modules/%s.EXT", moduleName);

Resource baseResource = classpathRoot.forFile(baseName);

for (String extension : extensions)
{
resource = baseResource.withExtension(extension);

if (resource.exists())
{
return resource;
}
}

// Return placeholder for null:
return classpathRoot;
}

My module is not listed in shimModuleNameToResource, and does not exist in 
/META-INF/modules/%s.EXT. The result is an empty classpathRoot.


I think I don't fully understand JavaScriptStack. I think a method is missing: 
Map getJavaScriptModules(). I would like 
to have a example of how to include a AMD/UMD module. What about support for 
CommonJS?




In the debugging process I found that @Contribute(ModuleManager.class) was the 
perfect choice for me.

@Contribute(ModuleManager.class)
public static void setupMyBaseModules(MappedConfiguration 
configuration, @Symbol(SymbolConstants.PRODUCTION_MODE) boolean productionMode) 
{
String[] reactModules = {"react", "react-dom"};
String ext = productionMode ? ".min.js" : ".js";
for (String m : reactModules) {
configuration.add(m, new JavaScriptModuleConfiguration(new 
ClasspathResource(String.format("META-INF/assets/js/%s%s", m, ext;
}
}

I think I was fooled by:

The documentation for ModuleManager.class say:
"...This is primarily used to wrap non-AMD compliant libraries for use with 
RequireJS"

The internal variable Map shimModuleNameToResource in 
ModuleManagerImpl. The shim prefix...

Hi, 

It has been a while since I last fought the module system, but in some 
cases I've used a request filter to map between module and asset paths 
(triggering on known module paths and then returning permanent redirects to 
the actual asset urls in the filter) - This was necessary in order to get 
stuff like CK editor to load properly as a module and still allowing it to 
dynamically require its plugins IIRC.

I believe your error was having the getModules() method above return a list 
with 'react'. According to its JavaDoc, getModules() must return the 
modules on which this stack depends. It doesn't actually depend on the 
'react' module. Please try having that method return an empty List and tell 
us what happens. 

You may also need to move react.min.js to 
/META-INF/modules/react/react.min.js.

Subject: Re: Contribute requirejs.config.paths to ModuleManager

I'm wondering here whether the best approach is the one you've chosen here,
usually used when you're dealing with non-AMD-module-compliant JavaScript
libraries, while React is compliant. I believe you should create a
JavaScriptStack with the React .js files, contribute it to the
JavaScriptStackSource service, then add your module to the core one (i.e.
the one included in all pages). See
https://tapestry.apache.org/javascript-modules.html, section Aggregating
Modules:

Because Tapestry is open, it is possible to contribute modules even into
the *core* JavaScript stack.  This is done using your application's module:
@Contribute(JavaScriptStack.class)
@Core
public static void addAppModules(OrderedConfiguration
configuration) {
configuration.add("tree-viewer", StackExtension.module("tree-viewer"));
configuration.add("app-utils", StackExtension.module("app-utils"));
}
So yes, Tapestry already supports what you want. :)

RE: Contribute requirejs.config.paths to ModuleManager

[Svein-Erik Løken]

React can in theory be used in all pages (globally). It will be like a core 
library for me, like jquery, underscore, bootstrap, etc. In TypeScript I am 
using
"compilerOptions": {
"module": "amd".

I have written a service:
@Override
public void appendToModulePath(JSONObject cfg) {
javaScriptSupport.addModuleConfigurationCallback(configuration -> {
if (!configuration.has("paths")) {
configuration.put("paths", cfg);
} else {
configuration.getJSONObject("paths").putAll(cfg.toMap());
}
return configuration;
});
}

MappedConfiguration, as far as I can remember, doesn't accept null as the

I'm afraid this isn't the correct way of using
JavaScriptSupport.addModuleConfigurationCallback(). It should be used while
rendering a page or handling an event. The way you did it above, you're
trying to add JavaScript at application startup. You need to do this in
page or component classes.

Define "globally", please. All pages, including error ones? Most pages? The
better way of doing this is moving this code to a mixin and apply it to the
pages where you need React. If you want it in all pages, you can contribute
a ComponentClassTransformWorker2 to the service with the same name which
applies the mixin to all pages. See
MutableComponentModel.addMixinClassName().

Contribute requirejs.config.paths to ModuleManager

[Svein-Erik Løken]

Trying to use TypeScript and React with Tapestry:

In TypeScript I need to use:  import * as React from "react";

I would like to load react: react.min, so I have to set paths: {...}

The configuration should be set at startup, but I cannot figure how to do it. I 
can set requirejs.config.shim, but not paths.

I tried to load it with @Contribute(ModuleManager.class), but could not figure 
out how.

PSEUDO CODE
@Contribute(ModuleManager.class)
public static void setupMyBaseModules(MappedConfiguration 
configuration) {
JSONObject pathsConfig = new JSONObject(
"react", "react.min",
"react-dom", "react-dom.min"
);
AMDResourceConfiguration paths = new AMDResourceConfiguration("paths", 
pathsConfig);
configuration.add(null, new JavaScriptModuleConfiguration(paths));
}


Tried to load it this way:


@Startup
public void registerToClearPlasticProxyFactoryOnInvalidation(JavaScriptSupport 
javaScriptSupport) {
ModuleConfigurationCallback callback = new
ModuleConfigurationCallback() {
@Override
public JSONObject configure(JSONObject configuration) {
configuration.put("paths",
new JSONObject(
"react", "react.min",
"react-dom", "react-dom.min"
));
return configuration;
}
};
javaScriptSupport.addModuleConfigurationCallback(callback);
}

[ERROR] ioc.Registry org.apache.tapestry5.ioc.util.UnknownValueException: No 
object of type org.apache.tapestry5.services.javascript.JavaScriptSupport is 
available from the Environment.






Now I am loading the configuration in @SetupRender, but it should be loaded 
globally.


@Inject
JavaScriptSupport javaScriptSupport;

private static final ModuleConfigurationCallback CALLBACK = new
ModuleConfigurationCallback() {
@Override
public JSONObject configure(JSONObject configuration) {
configuration.put("paths",
new JSONObject(
"react", "react.min",
"react-dom", "react-dom.min"
));
return configuration;
}
};

@SetupRender
public void configureRequireJS() {
javaScriptSupport.addModuleConfigurationCallback(CALLBACK);
}

Can this be configuration be contribute to the ModuleManager.class? I think 
this should be supported in Tapestry.

Hi! 

This is due to HTTP, not Tapestry itself: you cannot have two different 
responses to the same request. So, you either rerender the page to clear 
the errors (which calling form.clearErrors() is actually doing, even if you 
cannot see the results) or returns a binary download (StreamResponse), but 
not both. 

You'll need to write some JavaScript for that, so either the form 
submission or the file download request is done through JavaScript. Maybe 
the easiest solution, even if not pretty, is to return null in onSuccess(), 
rendering a

Hi Joshua,

It depends only on the container you are using to deploy the Tapestry

You only have to run this once, so I would recommend command line. The Tapestry 
project will not use the maven-archetype-plugin.

Hi! Nice! :)

You don't pass it to the event, but to the t5/core/ajax() function. Check
the data property of the options parameter in
https://tapestry.apache.org/current/coffeescript/ajax.html. Basically, you
pass an object with the key/value pairs you want passed as parameters:

ajax('answer', {
element: $('#result'),
/* Here it goes */
data: {
queryParameter1: valueParameter1,
queryParameter2: valueParameter2
}
/* Here it ends */
success: function(response) {
$('#result').text(response.json.origin);
}
});

The @PublishEvent was a big improvement 😊



I am using it already. I have created a working demo. I really like that it is 
so easy to stop hardcoding of event url.

Tapestry Quickstart problems

[Svein-Erik Løken]

The Quickstart project demonstrates how fast it is to start developing a 
Tapestry project.

I have been using it for a new project, but could not debug JavaScript. (I am 
using IntelliJ). I could not understand why, but after several hour a found out 
that configuration.add(SymbolConstants.MINIFICATION_ENABLED, true); was set in 
AppModule.java. I don't understand why this is set. I should not be set!!! If 
SymbolConstants.PRODUCTION_MODE= true then SymbolConstants.MINIFICATION_ENABLED 
is set to true.

Using maven3  I got error:

RE: Swipe and touch

[Svein-Erik Løken]

E.g. having a sidebar-flip on the edge of the screen, people will swipe on 
touch devices. On PC people will click.

Swipe down if on top of to refresh/reload, swipe right to go back, swipe left 
to go forward/next etc…

Subject: Re: Swipe and touch

I think that embedding a “touch” solution in T5.4 is a bad idea. This has been 
a fast-moving area, with lots of device-, and OS-version-, compatibility 
issues. Witness all of iOS’s touch-scroll issues over various releases.

I think the best we could do is have a plugin if someone’s willing to support 
it, but who’s willing to keep lots of old and new devices of various brands 
around? The next best thing is to provide sample solutions in the wiki.

Having said that, I think most of my iOS issues (in Safari and Cordova-based 
apps) disappeared with iOS 8.0. Touch usually works without any coding. Is that 
true for Android and other? What is an example of a “touch” issue you have?

These days the only effort I have to put in for “touch” (i.e. explicitly 
converting taps to clicks) is sortable ( http://jqueryui.com/demos/sortable ) 
and Cordova calendar.

BTW, swipe may be different. Currently I don’t use it.

RE: Swipe and touch

[Svein-Erik Løken]

I have no problem adding javascript libs using RequireJS. On my web site 60% of 
the end-users are using touch devices. To support then I have to handle some 
touch and swipe events. I think Tapestry also need to do that in upcoming 
versions.

I think the way to go is not to expose them / use them directly in onClick.
Instead you bind them in a module (either using t5/core/dom or jquery).
That way you are also keeping your global (script) scope much cleaner.

Lots of the tapestry framework client side code use this pattern.

Swipe and touch

I cannot find any swipe and touch JavaScript library in Tapestry. Are there any 
plans to include one in Tapestry in the future? If it is - I will use that 
library now. The Tapestry dev team use to find the best library :) It seems 
that Hammer JS and Touch Swipe are popular(?). Any recommendation?

Is there any example to use this service ?

You can always create a Jira ticket asking for a new configuration symbol
to be created to turn off logical page name shortening. Or, as Dmitry
already suggested, you can use URL rewriting to shape the URLs to your
needs. :)

RE: TLS termination proxy and Tapestry

[Svein-Erik Løken]

My feeling is that it's for SSL/HTTPS set up in Jetty/Tomcat etc  (no proxy in 
front needed) use:

public void contributeMetaDataLocator(MappedConfiguration 
configuration) {
configuration.add(MetaDataConstants.SECURE_PAGE, "true");
}

-- or secure pages with annotation:

@Secure

-- or folders with:

public void contributeMetaDataLocator(MappedConfiguration 
configuration)
{
configuration.add("admin:" + MetaDataConstants.SECURE_PAGE, "true");
}


If behind a TLS termination proxy use:
tapestry.security-enabled= false

The latter seems most intuitive also, because pages are unsecured in the 
tapestry application/servlet. The TLS termination proxy takes care of the 
security.

RE: TLS termination proxy and Tapestry

[Svein-Erik Løken]

With my configuration with -Dtapestry.secure-enabled=true the private String 
org.apache.tapestry5.internal.services. LinkImpl::buildURI(LinkSecurity 
security) return the absolute URI.

Using: 

public void contributeMetaDataLocator(MappedConfiguration configuration) { 
configuration.add(MetaDataConstants.SECURE_PAGE, "true"); 
}
With -Dtapestry.secure-enabled=true also works.

Still need to set X-Forwarded-Proto="https" to have request.isSecure() return 
true.

Which one is the preferred method?

When you say you are avoiding absolute URLs, where have you noticed this? I

Now, I’m no expert on this kind of configuration, and its a while since I set 
this all up, so forgive me if I have my wires crossed. Also, our site’s load is

In production we run pure HTTPS. We force all HTTP traffic to HTTPS by setting 
this in AppModule: 

        public void contributeMetaDataLocator(MappedConfiguration configuration) { 
                configuration.add(MetaDataConstants.SECURE_PAGE, "true"); 
        } 

We’re using mod_proxy and mod_ssl in Apache, no HAProxy. So Apache is 
terminating the SSL/TLS. 

We use: 

        -Dtapestry.secure-enabled=true 

We tell mod_proxy this: 

        ProxyPreserveHost On 

and we use the following to convert the request to AJP, because app preserves 
the HTTPS headers. 

        ProxyPass /myapp ajp://app:8009/myapp retry=5 
        ProxyPassReverse /myapp ajp:app:8009/myapp retry=5 

This all works great for us. So what’s the URL issue again?

RE: TLS termination proxy and Tapestry

[Svein-Erik Løken]

Tanks for confirmation on this!

What about make note on this in the documentation 
https://tapestry.apache.org/security.html?

It's not obvious that X-Forwarded-Proto="https" should be set in the TLS 
termination proxy. Other X-Forwarded- is often set default in the proxy, like 
X-Forwarded-For.

And the tapestry.secure-enabled = false.

TLS termination proxy and Tapestry

[Svein-Erik Løken]

Using HAProxy or Apache HTTP Server as a TLS termination proxy I found that 
setting X-Forwarded-Proto="https" in the header on the proxy 
org.apache.tapestry5.services.Request::isSecure returns true . That's good!
In tapestry.production-mode=true I am getting absolute URLs. E.g. 
http://example.com/index.mycompo.form.
By setting -Dtapestry.secure-enabled=false seems to solve this. Now I am 
getting a relative URL. (/index.mycompo.form).
I can see that with X-Forwarded-Proto="https" set, 
org.apache.tapestry5.internal.services. 
RequestSecurityManager::checkPageSecurity returns LinkSecurity.SECURE. That's 
good!

For me it seems that this is the correct solution, but I find it nice if some 
tapestry experts can confirm this!

BTW: I have been using T54 since the first beta and think it is a huge

lot of javascript interacting with T54 and uses ajax, zones, bootstrap without 
problems.

BTW2: Is there any books covering Tapestry 5.4 in English? I have this

RE: Make Tapestry add an id to the tag of the grid

[Svein-Erik Løken]

I think data-id is cleaner than setting some class attributes. I use class 
attributes for style/css.

What if tapesty used data-tapestry-id internally t:id=""? Users could then use 
the id="" attribute directly from javascript for elements in zones.

Tapestry does generate some “data" attributes, eg. data-validate, 
data-update-zone, data-async-trigger, and data-dismiss-url; but data-id is not 
one of them. Svein added data-id himself, but he could have called it anything 
so long as its name doesn’t clash with a Tapestry-generated one.

For anyone unfamiliar with “data” attributes, here’s some good info:

Hi everybody,

resulting HTML does not have an id attribute in the corresponding  tag, 
so I cannot select the table through jQuery or retrieve it through JavaScript; 
I cannot assume that the page has only one grid so I need the  tag to 
have an id.

I am using Tapestry 5.3.7. In the above mentioned thread the guy asked how to

RE: Inspection of Tapestry applications in IntelliJ

[Svein-Erik Løken]

Property need to be private to be resolved in the .tml

I use to add @SuppressWarnings("unused") when needed. I like to have no 
analysis error or warnings.  I wish that for my TML files too, but 
xmlns:p="tapestry:parameter" is not understood.  after  also 
gives me analysis error. I hope JetBrains will improve the Tapestry plugin when 
5.4 is released.

@SuppressWarnings("unused")
@Property
private String myProp;


My prop: ${myProp}

BTW: IntelliJ IU-142.4083 seems to be the best v15 EAP.

There have been some improvements in the recent v15 EAPs.

Also you can adjust the unused inspection to not trigger on certain
annotations. (I think it is some sub-menu found under the "light bulb" when
having an unused field marked)

No change event when datePicker updates t:datefield

[Svein-Erik Løken]

When fields in my side panel are updated, I call submit on the change event. If 
datePicker is used no change event are fired.

I could find a workaround without modification of datefield.js. Any suggestion?

One line added by me: _this.field.$.change();

Controller.prototype.onSelect = function() {
  var date;
  date = this.datePicker.getDate();
  if (date === null) {
this.hidePopup();
this.clearFieldError();
this.field.value("");
return;
  }
  this.field.addClass("ajax-wait");
  return ajax(this.container.attr("data-format-url"), {
data: {
  input: date.getTime()
},
failure: (function(_this) {
  return function(response, message) {
_this.field.removeClass("ajax-wait");
return _this.fieldError(message);
  };
})(this),
success: (function(_this) {
  return function(response) {
_this.field.removeClass("ajax-wait");
_this.clearFieldError();
_this.field.value(response.json.result);

//trigger change event on field
_this.field.$.change();

return _this.hidePopup();
  };

Is this correct? Isn't only

No! But I find this method much easier (This was a tip from Kalle Korhonen in 
this thread)

It should run for both methods.

BTW: In my real project I am not using contributeHibernateEntityPackageManager 
but  in hibernate.cfg.xml because IntelliJ use it to 
resolve table information.

The way this is done in tapestry makes sense for me. My main module is addicted 
to the common module. I don't want a loose coupling. I want to make code in the 
common module (code-)shared between different front-end modules (end-user, 
admin, web-service).

Oh yea! T5.4 is a success!

Tanks Kalle! A good replacement for  


I am moving a lot of code to my common module. I think the biggest challenge is 
how to access assets from JavaScript.

I moved the box_1.png, box_2.png, ... images to my common modules 
META-INF.assets.jacillacore.img.destinationStatus

public static void 
contributeComponentClassResolver(Configuration configuration) {
configuration.add(new LibraryMapping("jacillacore", 
"com.jacilla.core"));
}

My original code:
var iconUrl = "/img/destinationStatus/box_" + prepStatus + ".png";

Tried: 
var iconUrl = "${asset:jacillacore/img/destinationStatus/box_" + prepStatus + 
".png}";
and:
var iconUrl = "/jacillacore/assets/jacillacore/img/destinationStatus/box_" + 
prepStatus + ".png";


It did not work! Is it possible to access then directly for javascript?

To make it work I had to send the asset url's to the javascript module:
final JSONObject statusImages = new JSONObject();
for (int i = 1; i <= maxStatus; i++) {
final String format = 
String.format("/META-INF/assets/jacillacore/img/destinationStatus/box_%d.png", 
i);
Asset asset = assetSource.getExpandedAsset(format);
statusImages.put(String.valueOf(i), asset.toClientURL());
}
return new JSONObject(
"statusImages", statusImages,
"symbols", symbols);

Is this the correct way of doing this in T5.4, or could it be simpler?

Do you have Tapestry-Module-Classes set up in the common module? 
https://tapestry.apache.org/autoloading-modules.html

The hibernate.cfg.xml and maven dependency to hibernate should be set up in the 
main module.
E.g.

    org.hibernate
    hibernate-c3p0

The hibernate.cfg.xml and maven dependency to hibernate should be set up in the 
main module.

E.g.


org.hibernate
hibernate-c3p0




The only issue I am having is that my code for hibernate doesn't seem to
work quite as expexted. Ideally, this should be picked up from the happylib

public static void
contributeHibernateEntityPackageManager(Configuration
configuration) {
configuration.add("com.my.package.myentities");
}

However I am finding it only seems to work for me if it's in the main
projects AppModule.java, perhaps I have configured something wrong, or
perhaps this has to be in app module rather than in my shared jar?

I've put the hibernate entities that are shared between the projects in
there and so ideally the code should be in the shared library rather than
duplicated in both webapps (although it works as it is... any ideas what
may cause that?)

RE: Multiple domains, one webapp

WOW! Multi-module in Tapestry with Live Class Reloading is fantastic! Thanks 
for pointing me in the right direction Thiago!

To get live class reloading work for the common module in IntelliJ: Open 
Project Structure, Project Settings > Modules. Select the common module > Paths 
> Compiler output. Set Output path to the same path as the main project output 
path.

I have created a multi-module maven demo project for test and documentation. A 
page in the main project includes a component-class from the common module. I 
have demo of using assets (img and js-modules) and IoC service. Everything 
works with Live Class Reloading.

I am using a top-level pom (dependencyManagement, pluginManagement, 
properties), a modules pom (maven-root), the main project (war), and the common 
module (jar).

The main project and common module is both created from mvn 
-DarchetypeArtifactId=quickstart ..., with necessary modification.

I have documented all steps to make everything working in IntelliJ (plugin 
configuration etc).

Really! I am using IntelliJ IDEA Ultimate and NEED this functionality. Today I 
need to recompile all maven projects and restart jetty for every change to 
components and JavaScript modules (all resources) in the common JAR.

The common JAR project is included in the Project view. Has anyone solved this 
in IntelliJ IDEA?

I think 4) is the biggest downside in a multi-module project. Do you think 
Tapestry can do a Live Class Reloading of the common JAR included with 
contributeCoreLibComponentClasses?

RE: Detect jqXHR.abort()

I am now running Jetty 9.2.10.v20150310, but getting the same problem with a
similar warning in the log:

2015-05-11 09:25:55.695:WARN:oejs.Request:qtp1283939356-46:
org.eclipse.jetty.io.EofException: Early EOF

After some Googling it seems that this can happen on a server time out, or
if the client aborts the call.

I think Tapestry should stop this incomplete request from running any event
method. A request parameter = null could be coded to delete something.

RE: Detect jqXHR.abort()

[Svein Erik Løken]

Fiddler2 reports that the request is aborted most of the time. But some
request gets this warning from Fiddler2:



369 Content-Length mismatch: Request Header indicated 95 876 bytes,
but client sent 65 536 bytes.

369 Failed to obtain request body. System.IO.InvalidDataException
The request body did not contain the specified number of bytes. Got 65536,
expected 95876



This is the situation where _state = -13 and RequestParameter is null.
The request should be thrown and never call any methods which can lead

Maybe this is a jetty bug?

Ah, sorry... It looks like the browser actually closes the connection on
abort which is resulting in a partial request being sent to the server. I
have no idea how to detect this (possibly different per container too).

Since you've found a solution which doesn't abort I'd use that.

Cheers,
Lance.

RE: Detect jqXHR.abort()

[Svein Erik Løken]

Is it a bug in the JQuery xhr.abort() then? Debugging RequestFilter.service
I found that request.request.request._connection._parser._state = -13 (
org.mortbay.jetty.HttpParser.STATE_START) when things goes wrong (Should be
org.mortbay.jetty.HttpParser.STATE_CONTENT). I did not figure out how I can
test on this value, so I change my JavaScript code:





owner.simplifyPolylineLastCallCnt = 0;

owner.simplifyPolyline = function (tolerance) {

owner.simplifyPolylineLastCallCnt++;

var callId = owner.simplifyPolylineLastCallCnt;

$.post("/map/client/trackdraw:DouglasPeuckerSimplifier", {

}).done(function (data) {

if (callId != owner.simplifyPolylineLastCallCnt) return;

// DO THE WORK



Now I can set onDouglasPeuckerSimplifier back to allowBlank = false and
skip the == null test :-)



Forgot to tell that I am running Tapestry 5.4-beta-26.

The server will know about an aborted request as it's too late, the request
has already been sent. Abort is a clientside concept AFAIK which stops the
client from waiting for the response / processing it.

Detect jqXHR.abort()

[Svein Erik Løken]

In the web client the user can use a  slider to
reduce number of points on a polyline.

To be sure to only pick last XHR request I call xhr.abort() on the
previous call.

The problem is that the onDouglasPeuckerSimplifier(...) fail. I found a
bad(!?) workaround by adding @RequestParameter(allowBlank = true) to
both/all parameters and return if some of them are null.

I was looking for values indicating that the request was aborted in
org.apache.tapestry5.services.Request.

In my log I am getting: WARN:  org.mortbay.jetty.EofException

How can I detect if the XHR request is aborted?

JavaScript:
owner.simplifyPolyline = function (tolerance) {
if (owner._xhr != null) {
owner._xhr.abort();
owner._xhr = null;
}
owner._xhr =
   $.post("/map/client/trackdraw:DouglasPeuckerSimplifier", {...
   }).done(function (data) {...
   }).always(function () {
 owner._xhr = null;
   });
…

Java:
private JSONObject onDouglasPeuckerSimplifier(
@RequestParameter(value = "latLngs", allowBlank = true) JSONArray
latLngs,
@RequestParameter(value = "distanceTolerance", allowBlank = true)
Double distanceTolerance) {
if (latLngs == null || distanceTolerance == null) {
return null;
}
...

Live Class Reloading of Autoloading Modules

[Svein Erik Løken]

How can I get an auto loaded module live reloaded?

Confiuration:

maven-jar-plugin




com.company.core.services.Tjac3CommonModule






@Contribute(ComponentClassResolver.class)
public static void
contributeCoreLibComponentClasses(Configuration
configuration) {
configuration.add(new LibraryMapping("companycore",
"com.company.core"));
}



I added a symbolic directory link in the tapestry.app-package:

src\main\java\com\company>mklink /d core
..\..\..\..\..\..\..\tjac-common\tjac-core\src\main\java\com\company\core

Now it works, but in IntelliJ all classes in the core module duplicated.

I have been searching for a way to contribute the core library to be live
class reloaded.

Is it possible?

How to clear the autocomplete cache?

[Svein Erik Løken]

Search box on a map:



I need to call Bloodhound.clearRemoteCache() in typeahead.js

Did not find out how to access the engine variable in autocomplete.js.



Temporary hack/workaround:

I added $field.data("engine", engine); to autocomplete.js

engine.initialize();
dataset = {
name: spec.id,
displayKey: _.identity,
source: engine.ttAdapter()
  };
*  $field.data("engine", engine);*
  return $field.typeahead({
minLength: spec.minChars
  }, dataset);
};
return exports = init;
  });



Now I can clear cache with:

var ttInput = $(this._searchField).find("input.tt-input");
ttInput.data('engine').clearRemoteCache();



I don't want to modify t5/core/autocomplete.js



Hope someone can help me with a better solution!

IntelliJ IDEA 13.0.2 x64 Tapestry plugin not working correctly or lacks functionality for TML files

[Svein Erik Løken]

For ordinary HTML code, like , navigation/usage is
not working for included CSS files.

Code completion does not work for: ${asset: |}, ${message: |}, .

Because Tapestry gives excellent exceptions for wrong ${asset: |},
${message: |} etc, I think lack of navigation for CSS is the biggest
issue.

I tried to reassign *.tml to other File Types (Settings > Editor > File
Types). I found "Jinja 2 template files" usable. This template accepts the
':' inside ${ }. It is now possible to navigate to declaration (Ctrl+B)
and find usages (Alt+F7). Switching file type back and forth if not a good
solution.

My Tapestry plugin info:
   Name: Tapestry support (Bundled)
   Description: Provides Tapestry 5.1 integration.


Is my IntelliJ configuration wrong or does the Tapestry plugin lack this
functionality?

S-E

RE: IntelliJ IDEA Tapestry plugin existence

[Svein Erik Løken]

Great to hear! I am using the Ultimate Edition of IDEA and the Tapestry
plugin. After reading your mail I found this project
https://github.com/Widen/tapestry5-idea and feel relieved that the plugin
is under active development.

IntelliJ IDEA comes with a great Tapestry Plugin which is under active
development:

http://www.jetbrains.com/idea/webhelp/tapestry.html

However, it is only included in the Ultimate Edition of IDEA:

IntelliJ IDEA Tapestry plugin existence

[Svein Erik Løken]

After a lot of research Tapestry seems to be the right choice for my next
project. I found Tapestry through the New Project Wizard in IntelliJ. The
plugin project TapIDEA/Loomy does not exist anymore, so I am worry about
updates to this Tapestry plugin. Do you think this plugin will be removed
in some future IntelliJ release?
