Re: dynamic forms concept & possible solutions

[Ville Virtanen]

I think Thiago means onSubmit()

(If there are errors, it will never reach on success, right?)

This also means that client side validation must be disabled, or then a 
bit of JS must be used to disable it for the hidden button. (Js 
interface also exists to submit the form iirc, but for these bits 
someone else knows better than me probably.)

VS: tapestry + maven + jboss tools + hot deploying ?

[Ville Virtanen]

Live class reloading works in JBoss too, at least the last time I used it.
(7.x.x) You have to make your IDE to compile directly to the web container
exploded directory structure. This is specific to your IDE / web container,
and not really Tapestry. 

First of all read this: https://tapestry.apache.org/class-reloading.html
especially "Troubleshooting Live Class Reloading" and "If Live Class
Reloading doesn't work". 

https://www.google.fi/search?q=eclipse+compile+on+save 
https://www.google.fi/search?q=eclipse+change+output+directory 

If you want full code-refresh-view cycle, you should look at
http://zeroturnaround.com/software/jrebel/ Tapestry only changes the classes
on the fly that it manages, but not the others. I've seen that Tapestry's
offering is enough for most setups, but I've always struggled a bit with
large multiproject setups, as only the main project is easy to get refreshed
on the fly. If someone knows a way to do it, please let me know.

I don't think the question was about HA, but here goes nothing: if you're
going to have high availability site, you should have multiple backend
servers that you can bounce one by one. Have your load balancer(s) to
automaticly ping back end servers and drop dead ones and add resurrecting
back, remember to replicate session or go stateless. The services behind the
web application servers must also be ofcourse clustered and accessed through
LB ip address for an example.

In that setup you can freely stop and start nodes, provided that the
remaining ones have enough power to serve incoming requests. Script you
deployment so that it automaticly stops a node, redeploys, starts it back
up, moves to next node after your monitoring tells the node is back online,
otherwise retries. The tools to make this happen may include nagios
(http://www.nagios.org/), new relic (http://newrelic.com/), chef
(http://www.getchef.com/chef/) / puppet (http://puppetlabs.com/)

I've never had to operate a high-availability site, so I've not needed to
deal with this. I've always had a maintenance window available.

Some years ago I used to develop in JBoss with an expanded EAR, and hot
deploy worked fine, with the usual caveat that eventually you'll get PermGen
errors.

I know of many cases of Tapestry 5.3.x web apps running on Java 1.7 and
Tomcat in production. No problems, as long as the version of Tomcat chosen
is Java 1.7-compatible.

VS: How to use grid with large data sets.

[Ville Virtanen]

The griddatasource is natural fit for sql databases, but
lucene/solr/elasticsearch etc. may not fit it 100% 

That said, you can access the current page of the grid that is selected
(grid. getCurrentPage()) and rowsPerPage (grid. getRowsPerPage())  and do
the math yourself to be able to pull in correct content in the first place.

Tapestry uses the total amount of rows available to only make sure, that the
selected page is not out of the range of possible pages, and that the end
index is never more than there actually are rows. (The last page may not be
full.)

Aihe: Re: How to use grid with large data sets.

I wouldn't say it's premature optimization when I'm essentially performing
two of the exact same free text queries, it's twice the work ;-) My company
is hosting our dev database remotely on awful hardware to help us to find
performance issues. They believe if we can make something fast on dev, it
will be lighting fast in production, so everything counts lol.

Now if I understand GridDataSource correctly, you need to return the count
in availableRows() before the prepare() method can be called, is this
correct? If that is the case, I'm not sure how to go about combining this
into a single query do to the fact I would first need to get the count
before prepare is called to pass in the start / end index.

hibernate-search, which is based on the lucene free text search engine will
return the total filtered result count while only returning the pagination
results. When using the Tap5 loop component, I typically just return an
object containing the total count and an array list of the results, but
seeing the prepare is called secondly, I'm not sure how to do this. I guess
worse case I can just do two queries.

Aihe: How to use grid with large data sets.

Hello, I'm wondering how to use the grid component with large data sets.
Currently the grid is grabbing the entire data set rather than a sub set.
How do I pass back the current page and row count as well as the sorts? Can
this be done with the grid component, or would I need to builds something
custom with a loop?

Aihe: Re: BaseURLSource with access to current request

Your ClassCastException is caused by using configuration.add(…, …) instead
of configuration.addInstance(…, …)

If you find that contribution to ServiceOverride fails causes circular
dependency you can decorate instead of override:

static BaseURLSource decorateBaseURLSource(BaseUrlSource default, @Autobuild
MyBaseURLSource override) {
   return override;
}

Another option is to @Inject RequestGlobals instead of Request and call
getRequest(). This might eliminate the circular dependency too.

VS: BaseURLSource with access to current request

[Ville Virtanen]

Hi,

this is unfortunate and I have a fix for it, but a hackish one. The injected
Request is a proxy, so you can do this:

create empty container service, and inject it to the baseurlresource (just
like the request earlier.) Add setter to your container service for the
request, and contribute startupservice with a code piece that injects the
request and your container service, and then just putthe request to your
container service's setter, and then it will be there when the first request
comes in. This works because the injected request is actually a proxy, and
not an actual request. Haven't tried that though, so no guarantees. Note
that the container service must NOT declare the request in the constructor.

Docs to add startup code: http://tapestry.apache.org/registry-startup.html

Ps. If anyone has better fix for this, please share as I'm interested too.

[Ville Virtanen]

If that is not enough, you can also inject the request and us it in the
contributed BaseUrlSource to sniff the host.

public static void contributeServiceOverride(final
MappedConfiguration configuration, final Request request) {
BaseURLSource source = new  BaseURLSource()
{

  public String getBaseURL(boolean secure)
{

   String protocol = secure ? "https" : "http";
   int  port = secure ? 8443 : 8080;
  request... instead the line below.
   return String.format("%s://localhost:%d" , protocol,
port);

}
};
configuration.add(BaseURLSource.class, source);
}

VS: Eclipse Tapestry5 Plugin update

[Ville Virtanen]

Hi,

 

confirmed here too, I get 

 

”Unable to read repository at
https://dl.bintray.com/anjlab/eclipse/content.xml. Caused by:
javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated”

 

Can’t wait to try this out though!

Hey this looks great!
I'm having some problem though, when I tried to update the plugin I always
get a popup like following:

Please provide login details for dl.bintray.com:
username:
password:

I don't know if this is a problem on my end or not, because I have not had
this before (also not when I installed the first version of your plugin)
So yeah not sure what is going on here, but others don't have this problem?

Nathan

Just found few bugs when assets couldn't be resolved but they are present,
will fix this in next release also.
 
 

Fixed in version 1.1.2, available for update now.
 
 

As you understand this is a (always) beta release and is not well tested,
so install it, use it and post your feedback and bug reports to the project

Looks like the code that checks for case mismatch is broken when the path
separator is different.  It must be hard coded to look for "/", which is a
problem on Windows.

5.4-alpha-15 resource exceptions

[Ville Virtanen]

Dear list,

 

just tried to upgrade from 5.4-alpha-14 to 5.4-alpha-15, but the log is
littered with exceptions like this:

 

Caused by: java.lang.IllegalStateException: Resource
classpath:com/orient/web/customer/base/SecureBasePage.class does not match
the case of the actual file name,
'E:\projects\Orient\customer\target\classes\com\orient\web\customer\base\Sec
ureBasePage.class'.

 

java.lang.IllegalStateException: Resource
context:WEB-INF/customerclient.properties does not match the case of the
actual file name,
E:\projects\Orient\customer\src\main\webapp\WEB-INF\customerclient.propertie
s'.

 

I'm running a maven build with jetty:run. What should I change to get up &
running?

Re: Why would I choose JQuery?

[Ville Virtanen]

Portlet support and this Js fix are the most important new features.
Especially the no-portlet support part stopped T5 in recent evaluation to
build SAP front end and handling portal for multinational customer running
Oracle's weblogics.

Re: Why would I choose JQuery?

[Ville Virtanen]

Hi,

there are several reasons:

1. It's widely in use and actively developed. Even endorsed by Microsoft.
 ("Microsoft now fully supports jQuery and distributes it with the ASP.NET
Model-View Controller (MVC) framework. Furthermore, extensions have been
deve..." source: http://msdn.microsoft.com/en-us/magazine/dd453033.aspx)
2. It is released much more frequently than Prototype - the fear that we're
using dying js stack is enough to convert..
3. Easier to find help (Bigger community, more books etc.)
4. More advanced

The last part of course is debatable. Strong commitment from big players
make it safe bet.

Re: T5: How to have .tml/.properties files in the same directory as the .java files

[Ville Virtanen]

T5 application works ok as is if the files are in the same directory. 

If you use maven, then the maven default structure layout dictates that the
non-java files must be in resources or webapp folders. (The build process
copies the resources to the same directory structure from java and
resources.) 

Now you want to tell maven to also copy the tml and properties files from
the java side. One way to do this is to alter your pom.xml: add this inside
the build tag: (This is not tested, just something I typed on the fly. There
are better ways to do it.)



src/main/java
false

**/*.*


**/*.java
**/*.class




On the other hand, there is support for IDE:s. We are using Netbeans
support, which let's users change (and open if not already open) between
.tml, .java and .properties files.

Re: for IE

[Ville Virtanen]

On a side note:

you can use the onAction(possible_context) to catch any action made by any
link. Also, you can construct the context for the pagelink (or actionlink)
in the java file, just return new Object[]{value1, value2...} from the java
method. ()

Re: for IE

[Ville Virtanen]

I rolled a component that uses the IE specific tag to render normal button if
the used browser is less than IE 8. (IE 8+ handles it correctly)

That wasn't the greatest solution, but it worked. Also it only matters when
you have more than one button in the form, so single button forms can be
implemented as if it works ok in ie.

 - Ville


IE8 or greater or non-ie browser button

Re: Asset in css file?

[Ville Virtanen]

The most efficient way (cpu cycle wise) is to bypass Tapestry all together
and let httpd share the images. This approach however lacks the ability to
version assets using the T5 facilities.

The best way IMHO is to use relative paths in css (if there are "images" and
"css" folders, then the images are referenced like ../images/image.png),
this way the versioning is preserved and it just works. This method
obviously has some limitations also. (Works only when your image and css are
in the domain.)

The images are exposed to web via two urls: versioned and non versioned.
Hardcode one of those to the css is also an option. Use firebug or similar
to get the url. If you use versioned url, you may have to change the url in
css when upgrading the 3rd party lib.

You don't have to (atleast in 5.1) expose the image as an asset to reference
it in css or html.

Re: Dynamic Type

[Ville Virtanen]

The only thing that I can think of is delegate and blocks.

Is there a reason why the layout cannot be an empty component with a
delegate, and then the delegate gets the block to render from java property
that determines which (layout)block to use? In this model the block contains
the actual complete layout?

All (layout)blocks must of course have the same parameters etc. The page
content could be then made available to the layout block as a ... well
block, which could be then rendered using a ... delegate.. :)

also make sure that you are NOT logging too much in production, that can

 Have you checked if the bottleneck is elsewhere? In the database access
 or a
 server with other high CPU or I/O apps, for example? I never had this
 problem.

Re: Using PageResponseRenderer.render() in T5.2?

[Ville Virtanen]

Hi

I've always used symbol tapestry.version
(org.apache.tapestry5.SymbolConstants.TAPESTRY_VERSION) and parsed it from
that. Just get rid of the dots and then 5.1.0.5 becomes 5105, easy to
convert to integer and perform all kinds of less than, equals or is greater
than comparisons.

RE: t:grid, inPlace and rowIndex

[Ville Virtanen]

Hi,

you can calculate the exact index of the row by injecting the grid to the
page and calculating it by using methods (getRowsPerPage() x
getCurrentPage()) + index.
(http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry5/corelib/components/Grid.html)

The index of course changes when you reorder the list. Also, this index
should be updated when doing inPlace update as the index changes depending
in which place you insert the new row.

Should the list that contains the entities be a map instead? (Map) You may have to implement your own GridDataSource that uses the
map, as there is no automatic wrapping for that datatype. (See:
http://svn.apache.org/viewvc/tapestry/tapestry5/trunk/tapestry-core/src/main/java/org/apache/tapestry5/internal/grid/CollectionGridDataSource.java?revision=964086&view=markup
for reference implementation for collections.)

The cost to iterate the list when doing deletes shouldn't be that much
performance wise - and if you have so many entities that the cost is too
much you should consider implementing special GridDataSource anyway.

RE: Asset protection and upgrade notes

[Ville Virtanen]

Exactly, 

the message was only to point out that changes like these make library
writer's life hard in the long run. So I was only questioning the rationale
behind the change in no-slashes-in-virtual-folders and how it auto
contributes the associated contribution to ClasspathAssetAliasManager.

In my opinion that auto contribution should be removed.

The missing RegexAuthorizer is quite a wall to climb for me. Perhaps I need
to contribute my own implementation of AssetPathAuthorizer? Anyone?

Re: Asset protection and upgrade notes

[Ville Virtanen]

Also this choice forces us library writers to either

a) support two separate deployment jars for different T5 versions
b) fork the code depending on the T5 version

So my approach is probably this:
 public static void
contributeClasspathAssetAliasManager(MappedConfiguration
configuration, 
@Inject @Symbol(FckEditorConstants.EDITOR_CONTEXT) String
location,
@Inject @Symbol(SymbolConstants.TAPESTRY_VERSION) String
t5Version)
{
if(!location.equalsIgnoreCase("easyfck") ||
getTapestryVersion(t5Version) < 5106) {
configuration.add(location, "com/orientimport/easyfck/js");
}
}

private static int getTapestryVersion(String version) {
return Integer.parseInt(version.replaceAll("\\.", ""));
}  

Not elegant, not good code (assumes something about the future version
numbers..), not maintainable in long run, if these dicisions will keep
popping up.

Also the automatic classpath asset addition works for this library only if
the user who uses the library hasn't decided to use custom url for his/hers
fck editor. It should not be depended on the TAG prefix?

My 2c,

 - Ville

Asset protection and upgrade notes

[Ville Virtanen]

Hi,

I've been tracking the documentation to understand the change in asset
protection, but haven't found anything useful.

I've checked the upgrade guide from svn (last update 4 days ago):
http://svn.apache.org/viewvc/tapestry/tapestry5/trunk/src/site/apt/upgrade.apt?revision=948226&view=markup

But really it only mentions the no-slashes-in-virtual-folders restriction.
Where is the asset protection part or am I looking from wrong sources?

Also, what is the rationale behind removing library specific versions? Even
if the 3rd party library doesn't change any resources browsers are forced to
download all assets again when updating the main program. Technical
challenges I presume?

Anyhow, the info on asset protection is very important for me, or at least
just plain cold "We're working on it and have no eta.". (Then I know to stop
reading through sources.)

Re: EasyFCKEditor FileUpload with Tomcat?

[Ville Virtanen]

Hi,

yeah, the configuration differs how to set up this with different app
servers. (Or apache as we always use httpd to serve static files anyway.)

 - Ville

Ps. Wish that I had time to finish CKEditor integration, I already have
working version which needs polishing and documentation. The file uploader
part was a lot of work because CK has no open source file uploader.

Re: easyfckeditor and file upload

[Ville Virtanen]

Hi,

I think I solved this one. The findings show that FCK editor java
integration library could do little bit more descriptive errors... 

The SimleFckEditorConnector you supplied is a bit invalid. The method public
List> getFiles(ResourceType rt, String currentFolder)
throws InvalidCurrentFolderException, ReadException 

returns list of map. where the String is
net.fckeditor.connector.Connector.KEY_NAME or
net.fckeditor.connector.Connector.KEY_SIZE and the Object is either the file
name or file size.

It should be like this:
Map map = new HashMap();
map.put(Connector.KEY_NAME, "hct.log");
map.put(Connector.KEY_SIZE, new Integer(64));
List list = new ArrayList>();
list.add(map);
return list;

I hope that this gets you going :) You can test the default implementation
by NOT binging your connector, then easyfck will fall back to the default.
Then allow all in SimpleFckEditorUserRightServiceImpl and you can upload and
view images etc.

 - Ville

Ps. Take a look at FCK editor default implementation for details if you
whish to implement your own connector:

Hi,

can you attach the stack trace for further analysis? Also what servlet
container are you using to run software?

Re: Pretty Printing JSON

[Ville Virtanen]

Hi,

this definitely sounds something T5 should do as it is known to be developer
friendly and aid in debugging whenever possible. 

It sounds good to enable this in non-production mode and disable in
production.

Re: How to get rid of some T5 stack traces ...

[Ville Virtanen]

Hi, 

hrx -> xhr :D

It is true that T5 catches many of these
"I-did-not-even-know-something-makes-these" -requests, and it is good to
know of this happening.

Obviously I should also take a look at the URL re-write functionality.

Ps. It's minus 20 Celsius here... (-4 Fahrenheit) I'm freezing! :)

Re: How to get rid of some T5 stack traces ...

[Ville Virtanen]

Hi,

One way to prevent this is to contribute a T5 httprequest filter that just
redirects to error page if it detects a post url submitted using GET. (And
isn't hrx?) This is one of the T5 weaker sides I think. It produces many
like these in the production for us for a site that slightly altered url
layout, although these errors are rarely made by human.

Haven't seen that one on our production servers, however our servers are
getting hammered by someone trying to get /index.html which produces "there
is no such component in page... blah .. the valid components are...".

This can be fixed by implementing a component named html that does
absolutely nothing and placing it to the page.

Re: [T5.1.0.4] Distinguishing Between Internal and Scripts when Combining

[Ville Virtanen]

Hi,

GA works ok for us by just adding it to the tml as is instructed in GA site
- No need to use T5 facilities to include the script. (Done in layout.tml in
our case.)

This doesn't solve the external script problems, and may not work for you
but just thought to let you know.

RE: Advice on Tapestry5 best practise for user session data

[Ville Virtanen]

Hi,

as Thiago said you can access the application state using
ApplicationStateManager in services, but beware that this approach doesn't
work if there is no request. 

So, you cannot use the service anymore if the calling code is, let's say
some sort of batch job that has actually nothing to do with a web request.

IMHO web related stuff should never be accessed in low level services / dal
to avoid this. If you can live with that restriction it is ok to use
ApplicationStateManager.

Re: Installing easyfckeditor

[Ville Virtanen]

Hi,

Please include more of the stack trace so I can take a look at it. You
should be able to follow this guide:
http://t5-easy-fckeditor.kenai.com/Simple.html

I've also rolled out new version, 1.0.3 which fixes some problems with
application initialization that caused recursive problems. I will also
shortly release 1.0.4 which uses the newer java integration package 2.6
(http://java.fckeditor.net/) to provide the file upload capabilities.

Re: Advice on Tapestry5 best practise for user session data

[Ville Virtanen]

I would follow this guide:
http://tapestry.apache.org/tapestry5/guide/appstate.html
and make my own app state object, UserSession, which would contain the
needed per user data. (The keys anyway.) There can be services that provide
data based on these keys, and those services should also take care of
caching or more preferably use cache service(s) to do the caching. Cache
service can be implemented using ehcache (http://ehcache.org/) for an
example.

Make interface that the user session implements, then use this interface in
your service and dal methods as a parameter.

This way your system is also cluster ready, as long as the caching mechanism
is cluster friendly too, you could make it using mem-cached
(http://memcached.org/) and one of it's java clients or one of the java
caches.

If you require absolute scaling then throw out the session all together and
live with cookies or encoded urls, this way you can achieve truly stateless
server side and you can add more servers without any sort of sticky sessions
or session replication problems etc.

 - Ville

Ps. for 99% of cases using as light user session as possible + pure java
cache is the right way to go afaik, so consider sessionless + memcahced only
if you plan on running the software with loads or servers.

Re: Installing easyfckeditor

[Ville Virtanen]

Hi,

if you don't use maven you have to provide yourself also all the required
dependencies. (See http://t5-easy-fckeditor.kenai.com/dependencies.html to
view the list of dependencies.)

The jar must be in the project libraries so that the jar is accessible to T5
during runtime, so adding it to only build path may not be enough.

You really should use maven, follow this guide to setup your env:
http://www.troymaxventures.com/2008/05/tapestry5-netbeans-quickstart.html
but use the latest 6.8 instead of the 6.1 mentioned in the guide.

This way maven takes care of all those dependencies etc.

 - Ville

Ps. The project has moved to Kenai, so the 1.0.2 jar can be obtained from
mvn repository, just go with your favorite browser to
http://kenai.com/svn/t5-easy-fckeditor~maven-release-repository/com/orientimport/t5-easy-fckeditor

Re: Number Formatting in TextField (T5)

[Ville Virtanen]

Hi,

we actually made it the hard way and currently we have our own
BigDecimalFieldTranslatorImpl, which takes care of the actual validation, as
seen here:

public class BigDecimalFieldTranslatorImpl extends
FieldTranslatorImpl {

private final Locale locale;
private final int numberOfDecimals;
private final Field field;
private final MessageFormatter messageFormatter;
private final Messages messages;
private final boolean useGrouping;

public BigDecimalFieldTranslatorImpl(int numberOfDecimals, boolean
useGrouping, Locale locale, Field field, Translator translator,
MessageFormatter formatter, FormSupport formSupport, Messages messages) {
super(field, translator, formatter, formSupport);
this.locale = locale;
this.numberOfDecimals = numberOfDecimals;
this.field = field;
this.messageFormatter = formatter;
this.messages = messages;
this.useGrouping = useGrouping;
}

@Override
public String toClient(BigDecimal value)
{
if(useGrouping){
return NumberFormatUtility.formatWithGrouping(value,
numberOfDecimals, locale);
}
return NumberFormatUtility.format(value, numberOfDecimals, locale);
}

@Override
public BigDecimal parse(String input) throws ValidationException {

if(input != null) {
input = input.replaceAll("\\s", "");
}

BigDecimal result = super.parse(input);

if(NumberFormatUtility.hasTooManyDecimals(input, numberOfDecimals,
locale)) {
throw new ValidationException(formatMessage());
}

return result;
}

private String formatMessage()
{
if(numberOfDecimals == 0) {
return messages.format("integer-format-exception",
field.getLabel());
} else {
return
messages.format("fi.cerion.common.too-many-decimal-places",
field.getLabel(), numberOfDecimals);
}
}

}

However, to supply per field validation data to the validator we opted to
make our own service that is used to get the field translator:
public class CerionFieldTranslatorSourceImpl implements
CerionFieldTranslatorSource {

private final PersistentLocale persistentLocale;
private final TranslatorSource translatorSource;
private final FieldTranslatorSource fieldTranslatorSource;
private final ValidationMessagesSource validationMessagesSource;
private final FormSupport formSupport;

public CerionFieldTranslatorSourceImpl(PersistentLocale
persistentLocale, TranslatorSource translatorSource, FieldTranslatorSource
fieldTranslatorSource, ValidationMessagesSource validationMessagesSource,
FormSupport formSupport) {
this.persistentLocale = persistentLocale;
this.translatorSource = translatorSource;
this.fieldTranslatorSource = fieldTranslatorSource;
this.validationMessagesSource = validationMessagesSource;
this.formSupport = formSupport;
}

@Override
public FieldTranslator createBigDecimalTranslator(Field
field, int numberOfDecimals)
{
ComponentResources resources =
((ComponentResourcesAware)field).getComponentResources();
Translator translator =
translatorSource.getByType(BigDecimal.class);

return createTranslator(field, resources.getId(),
resources.getContainerMessages(), resources.getLocale(), translator,
numberOfDecimals, false);
}

@Override
public FieldTranslator createBigDecimalTranslator(Field
field, int numberOfDecimals, boolean useGrouping)
{
ComponentResources resources =
((ComponentResourcesAware)field).getComponentResources();
Translator translator =
translatorSource.getByType(BigDecimal.class);

return createTranslator(field, resources.getId(),
resources.getContainerMessages(), resources.getLocale(), translator,
numberOfDecimals, useGrouping);
}

private FieldTranslator createTranslator(Field field, String overrideId,
Messages overrideMessages, Locale locale, Translator translator, int
numberOfDecimals, boolean useGrouping)
{
MessageFormatter formatter = findFormatter(overrideId,
overrideMessages, locale, translator);
return new BigDecimalFieldTranslatorImpl(numberOfDecimals,
useGrouping, locale, field, translator, formatter, formSupport,
overrideMessages);
}

private MessageFormatter findFormatter(String overrideId, Messages
overrideMessages, Locale locale,
   Translator translator)
{
// TAP5-228: Try to distinguish message overrides by form id and
overrideId (i.e., property name) first.

String translatorName = translator.getName();

String overrideKey = formSupport.getFormValidationId() + "-" +
overrideId + "-" + translatorName + "-message";

if (overrideMessages.contains(overrideKey))
return overrideMessages.getFormatter(overrideKey);

// Ok, look for a simpler name that om

Re: Passing object as paramters to component

Hi,

define private YourObjectType param; variable to your component class and
use it. Annotate it with @Parameter annotation.

Then use your component like this:

Re: Tapestry 5 and Selenium

[Ville Virtanen]

Yep, that's what I was afraid of.

I don't have anything to base my opinion to, but I have a feeling that the
tests will be really easily broken if and when someone decides to change the
page layout etc.

This of course is not related to T5 at any level, but rather common problem.
And that's the only thing afaik that is holding us back from making more
business minded consultants to make n' bake their own tests. Well, that was
the dream anyway.. ;) (I suppose that given the nature of the best tools
today you have to be somewhat technology-aware to actually make meaning full
tests.)

Tapestry 5 and Selenium

[Ville Virtanen]

Hi,

I've googled around but couldn't find solution for this one. The problem is
that we have to test a form that is loaded using progressive display which
makes all the ids to be generated for each request.

Now, how can I use selenium.type to locate the correct input, when the input
name changes like this:

request one: mpo-1258bc89493_0
request two: mpo-1258bcae418_0
request three: mpo-1258dfea345_0

Has anyone solved this?

Re: collection of components within a page (Tapestry 5.1)

[Ville Virtanen]

Hi,

Don't loop your components, loop your data. If it is the name of the
component that is your data, then loop over the names and give those as
parameter to your boxes. Normally it would be orders or products or users or
what not that are looped through.

You don't have to give unique identifiers to your components if you don't
want to, so you can just have components without any parameters. (Obviously
:))

Take a look at http://tapestry.apache.org/tapestry5/tutorial1/hilo.html it
shows how you can make a loop that loops 10 times and creates new actionlink
every time. (Creating guessable links part) Source is the list that you
loop, and value is the variable that contains one list item at every
iteration of the loop. (So your component can be given one object at a time
as parameter from the list.) Tapestry takes care of your component
instantiation and instrumentation if you just follow the normal project
layout. (So that T5 knows which classes are components / pages. You can of
course use non-standard packages and instruct T5 to treat any class as
component.)

Hopefully this clarifies it a bit.

Re: Switching between Stage & Production DB with Tapestry5 & Hibernate3

[Ville Virtanen]

Hi,

we use our custom configuration file that reads everything from single file.
The application reads a system property that defines the location of the
conf file. This way, the jar and build process is the same for every
environment and the deploy procedure is just to copy the war to the server
(prod, pilot, internal test, demo etc..)

Also, this enables us to run our software in the mode we choose in every
environment: if we need to run in debug or development mode in production
that we indeed can. Also the log4j conf is read from outside the
war/exploded war, so that conf is also out of the build cycle.

The only downside is that we have to define the single configuration key to
catalina_opts or similar, but this setup has proven to be useful for us:
even the new guy can deploy to any environment, as the procedure is always
similar and there is no checklist ;)

Quick solution is to determine the wished configuration from the production
mode flag.

Re: Netbeans 6.7 tapestry 5 plugin support

[Ville Virtanen]

We use it, but we have inhouse modified version of it due to problems in tml
/ java class change functionality. (The original version does not know how
to resolve all possible template locations.)

I contacted the author if he would like to get / review the changes, but I
never got any reply back.

Anyhow, it really is usefull, atleast the tml / java class switch
functionality.

Re: tapestry 5.1.0.5 with php

[Ville Virtanen]

Technically possible, feasibility?

If you have httpd in front of tomcat or some other j2ee container that
drives T5, then the session state is held in httpd and can be accessed from
php also.

Only scenario that comes to my mind is app that has to transition to some
legacy system in some of the views... (In which case the state should be
transferred via the url and/or for an example shibboleth imho.)

Re: t5: redirect to a page in javascript?

[Ville Virtanen]

Hi,

this is not the best place to ask js questions, but my guess is 

1. The window.location accepts only full urls? (Or atleast the context start
/, window.location="/items")
2. Your method never gets called or the execution is halted in saveupdates()
(Which should have ; at the end of the line, like after "items"; also..)

Hi,

Do you ask is it possible to know which module has done the service bind or

You could guess something from the class name, but imho it sounds that there
is something wrong with the logic whatever you might be trying to solve.

Re: Slightly OT: Ad hoc connection pools

[Ville Virtanen]

Hi,

I would probably create service that handles the connection pooling by using
multiple pools that are backed up by some third party lib.

Service would take care of closing pools when the registry shuts down or the
pool has remained unused for certain period. Don't know how heavy it is to
initialize pools / how much memory will those pools use? Also it could be
done so that the user can have only one pool at a time to limit resource
usage.

The service could use ApplicationStateManager to check the user and
connection data from session transparently. Pseudo service code for one pool
/ user:

public Connection getConnection() {
 1. get user object from session
 2. get connection data from session
 3. get pool from hashtable by user id 
 4. check if the pool matches the connection data
 - if it does, update last access time ->  return connection from pool
 - if it does NOT or is null -> closePool(); + create and test pool, add
to hashtable, update last access time ->  return
}

public void closePool() { 
 1. get user data from session
 2. get pool from hashtable by user id
 3. if exists -> close, remove from hashtable
}

Of course the pool must be enclosed in class that contains last access
milliseconds, creation milliseconds, the actual pool, and the connection
data.

Also make a method that loops through all pools and closes and discards all
pools that have been unused for 30 mins or something to close connections

method every 5 minutes or something. (http://www.opensymphony.com/quartz/)

The last thing is to implement the registry shutdown method which closes all
pools.

Re: [t5] upgrade to java 6 and javassist

[Ville Virtanen]

Hi,

Also make 100% sure that there aren't multiple javassists (different
versions in classpath) AND that the included javassist version is the right
one. Check this from the produced war, do NOT trust what the ide is saying
;)

Sometimes we have had problems like this, but those were because maven
dependencies affected to the included javassist version.

We use java 6, and our compile targets are 1.6 in about ten projects, we
have multiple developers compiling with different versions of java and
haven't had any problems besides those javaassist version related.

The version of javassist that gets included for us is 3.9.0.GA

Ps. Below is the mvn configuration we're using w/ netbeans

Re: Announcment: T5 FCK editor integration library

[Ville Virtanen]

Hi,

We have been using FCK happily for ages now. This editor is tested at least
with the progressive display, but nothing more exotic. Perhaps I have to do
some test cases with zone.

Also, the total rewrite of FCK, now known as CKEditor looks much more
promising, that we are using also. I think I can publish a library as soon
as the CKEditor hits 3.0 final, now it is RC 1. Take a look :
http://ckeditor.com/ckeditor/3.0rc/_samples/index.html.

 - Ville

Ps. The yui library seems definitely worth looking...

Re: Announcment: T5 FCK editor integration library

[Ville Virtanen]

Mainly because we had it already as standalone jar, and the time that I would
have had to use before having commit rights to ChenilleKit would have taken
too long. Busy schedule as you might guess.

Also I see this as more of an standalone thing, not necessarily as part of
the application framework thing you have going on. Of course, you're free to
use the provided code anyway you see fit ;)

Also I'll be updating that jar as part of my job, which unfortunately
dictates what I can do and what not when I'm using the office hours for open
source. The dream lives that I could work full time for the benefit of open
source software :) In the mean time though...

Hi again,

I rolled new version that has 

1.5
1.5

tags set in build configuration. This should do the trick, right? (Have no
machine where I could verify with 1.5 java, and I'm too lazy to install one

Announcment: T5 FCK editor integration library

[Ville Virtanen]

Hello everyone

we have used FCK editor for quite some time now with file uploading
capabilities, and we needed the same functionality in several clients that
would have had to be kept separate due to licensing issues. Thus we agreed
to make it publicly available and so we have to keep only one copy up to
date.

Currently the project lives in http://code.google.com/p/easyfckeditor/, but
I hope that we get Tapestry 360 site soon. Also, are there any maven
repositories that would accept packages without much fuss? The using would
be _much_ easier if the library was in a maven repository.

Anyway, here is short description of the project (I hope that you enjoy, and
remember to give feedback.):

Easy Fck Editor is open source extension to Tapestry 5 that uses (as the
name implies) FCK Editor under it's hood to deliver easy richtext editor
component with file upload capabilities.
The main focus is to do everything Tapestry 5 way: you can work entirely
with the provided (and excellent I might add) IoC as developers are used to.
Also the idea is to really provide such documentation that it is easy to
follow and understand. Easy Fck Editor aims to be simple to use and yet
provide good interface to aid in extending and securing Tapestry 5 based
rich editor needs.
Why? Doesn't ChenilleKit already have one?

Easy Fck Editor project started because the editor in ChenilleKit couldn't
handle file uploads. Also I found that (at that time atleast) the
documentation was not on very good level. I also didn't need but a fraction
of what ChennilleKit provided. For me, I would be more merrier if there was
tiny bits that I can put together in the project pom, so that I could
"harvest" the libraries I need. This is also why I intent to package all
forthcoming Tapestry 5 extensions as separate jars where possible. (CKEditor
should follow shortly.)

Re: [T5.1] Obtaining Messages in Service

[Ville Virtanen]

Hi,

there are few possible solutions:

1. Pass the messages as parameter from the calling page or component to the
service

2. Return only codes or something that you translate to human readable form
in the page / component

3. If messages are errors, return your own exception that contains message
key or code that gets translated in the UI

4. Take a look at TapestryTestCase
(http://svn.apache.org/viewvc/tapestry/tapestry5/trunk/tapestry-core/src/main/java/org/apache/tapestry5/test/TapestryTestCase.java?revision=753426)
method messagesFor. Basicly you can load what ever to the MapMessages
implementation
(http://tapestry.apache.org/tapestry5.1/apidocs/org/apache/tapestry5/internal/services/MapMessages.html)
and use that OR you can load standard java ResourceBundle and wrap it with
MessagesImpl
(http://tapestry.apache.org/tapestry5.1/apidocs/org/apache/tapestry5/ioc/internal/util/MessagesImpl.html)

Remember that case 4 involves using classes that are marked as internal and
may change anytime.

Re: [Tapestry Central] Why chose Tapestry?

[Ville Virtanen]

Hi,

First we used eclipse too, but ran in far too many problems with maven.
Today we use NetBeans, which seems to do most of the things that we expect
it to. At first there was _really_ much resistance to start using NetBeans
which was seen as toy and not as an IDE for professional developer, but in
my opinion if you want an environment that _just_ works, use NetBeans.
(Especially if your developers aren't that familiar with Eclipse.)

Maven also caused a lot of trouble for us at the beginning. Some devs didn't
have any problems, some had more. The more resistance the dev had, the more
problems he/she also had...

Anyway, today when new developer starts (s)he installs maven, svn tortoise,
netbeans and downloads the project and then starts the app with mvn
jetty:run -> dev is ready to start coding. This process usually takes about
45 minutes, depending how long the machine downloads stuff and installs
java/netbeans. 

The start of new project does not take any longer than T4 project, but I
must admit that there is some learning curve when you come from T4 or some
other environments, after all, this is new and different system. However, it
is not black magic, and if you have experience with systems it shouldn't be
that hard.

The documentation is lacking, and is the next thing to be fixed (As Howard
has mentioned.). Also T5 should be as new-user-friendly as possible, which
clearly could be improved?

RE: Two Menu Components

[Ville Virtanen]

Hi, 

this is wild guess, but take a look at the environment? You can push, pop
and peek objects that are in the environment, shared by all enclosed
components.

Re: [Tapestry Central] Why chose Tapestry?

[Ville Virtanen]

Don't know if I double posted but..

Indeed, if you aim to code shit, please don't use T5 :)

The best case scenario would be that the compiler would detect all errors. 
The next best case would be that the app would point out what is wrong when
it starts.
The worst case is to have to click through the thousands of pages to even
detect that you can access it.

Re: T5: Huge t-formdata

[Ville Virtanen]

Hi,

Few suggestions: try 5.1, there are many optimizations in this release,
don't know if any of those are related to this though.

Also, does the size grow linearly with more objects in the row? How much by
per row? (Test with 100, 200, 300, 400, 500 etc.)

Include the tml and java, without those we're pretty much guessing what
might or might not go wrong.

Also t-formdata contains (i think) data about the state of the related form
components, so the complexity of the form might play role here also. So, if
possible simplify the contents of the loop by removing all unneccessary t5
components from inside it. Again, it would be easier to guess with some
source.

Next 5.1 bug fix release? (ProgressiveDisplay and chrome / ie8 woes)

[Ville Virtanen]

Hi,

sometimes chrome and ie8 don't make the request when using progressive
display. Symptoms: the ajax-loader.gif is displayed for the user
indefinitely and the server never sees the request. This can be fixed by
pressing refresh with shift. (Empty-cache-reload). So it is probably
prototype issue with these new browsers, right?

Are there any plans to publish new 5.1 series bug fix release once the next
version of prototype becomes stable? It has stayed as beta for quite long
time now, so release should be nearing...

The earlier proposed fix is to contribute your own exception handler, see

and 
http://wiki.apache.org/tapestry/Tapestry5RedirectException
for clues. 

Don't know how up-to-date those are.

Re: Component won't render its body

[Ville Virtanen]

Hi,

check that the associated .tml is really named correctly and is part of the
correct package. The case matters, it must be same in .java as it is in
.tml. The tml file is not mandatory, if it is omitted then the component
outputs only what the java class writes directly to the writer.

Re: Using "futures" to parallelize rendering of components

[Ville Virtanen]

Hi,

Don't really understand the question, but if you're having perfomance
problems then caching would be the way to go?

You can use blocks to separate what ever you wish to wrap as T5 components
and place them to one central page, from which those blocks can be used.

T5 caches all pages and components in it's own pools, and you can mark
content that can be cached with @Retain annotation.

I hope this gives some ideas,

 - Ville

Re: t5: InjectPage and context

[Ville Virtanen]

Hi,

Two solutions:

1. Use PageLink in tml. (And supply the context to it from the java class)

2. Use PageRenderLinkSource (return
PageRenderLinkSource.createPageRenderLinkWithContext(WriteMsg.class,
Object... context);)

Neither requires injected page.

Re: once-only onActivate method

[Ville Virtanen]

This probably is NOT the solution, as this method gets executed only once
when the page is loaded and added to the pool.

Multiple users and hundreds of requests can be served with only one call to
PageLoaded, if I understand it correctly.

The pageAttached and pageDetached events occur when the page is fetched from
the pool (attach) and returned back (detach). This occurs once per request.

The best solution that I can come up is to use additional context parameter
to simulate the activateExternalPage(), so when you use page link or similar
you can "notify" the page correctly.

I mean

onActivate(Long key, boolean fromAnotherPage) {
  //Do activateExternalPage() stuff
}

onActivate(Long key){
  if(noInitializationYetDone){
//do normal initialization
  }
}

onPassivate(){
  return key;
}

This way the normal page flow does the normal initialization on form
postbacks etc, and the special initialization can be done if the link that
directs to the page contains the magic boolean in the context.

However, this should be avoided by design, so that page can initialize
itself correctly without stale checks imho, so no data in session etc. (I
don't know how Cayenne works so this might not apply, but I've noticed that
this is best practise for our apps w/ hibernate.)

Re: T5.0.18: how to have variable data structures in a bean?

[Ville Virtanen]

Hi,

the given tml is missing encoder for the inner loop. Without this T5 uses
the default approach which is the highly inefficient
serialize-whole-thing-to-form-data. 

This encoder can be constructed in the bean itself (resident) but imho
should not be there, so the best approach (afaik) is to construct it in the
page based on the data that resident contains (So that one encoder is
created per resident for the profiles loop.).

 Add the encoder and if this doesn't work attach the associated java code
snippet also

Re: [REQUEST] Live T5 web sites, quotes, marketting

[Ville Virtanen]

Hi, 

nice to see what others are making. We use T5 to build different kinds of
systems for public and private sectors, but mainly budgeting and enterprise
resource planning and monitoring software. Currently we have 4 T5 systems in
production all in different client's environments, and two more projects are
nearing release almost immediately. 

Our software typically integrates to multiple other systems, like personnel
registries, data warehouses, salary systems, reporting systems etc. to
combine all the wonderful data already present in most companies and to
present it in usable and efficient way. The number of systems, old and new
that are in use in a typical firm is overwhelming.. 

We'll anyway T5 has proven to be stable, doesn't require much resources to
do it's tasks and is easy and reliable to integrate to almost anything. The
most important thing to us is that T5 allows us, you could even say directs
us, to architect our systems easily and well, it supports us to write
easy-to-understand code by removing all that clutter and exposes only the
real things we wish to do, which directly means less code, which directly
means quality and reduced costs (the drop of unsuccesfull code inspections
etc.) lowered bug fix times etc. And we can also sell cheaper in the first
place and win more cases, as development times have dropped. 

Also it can be seen that the developers who work with T5 are more motivated
and happy with their work than those that are still stuck maintaining old
Struts and servlet stuff. This cannot be calculated and is hard to prove,
but there is definitely that trend: whether developer maintains or creates
new functionality with Struts (or asp.net) they usually start with "why me,
couldn't xxx do it", where as with T5 software it usually is "ok, let's go
through the specs..." 

Before we have used Struts, plain servlets, T4 and we still use asp.net / C#
for clients that require it, and so far there just is no match for T5 when
software must be developed with minimum cost, but still to the standard and
professionally. (Which, in my opinion, excludes all scripting languages.) 

There definitely is learning curve (as with any new technology), but in my
opinion it definitely is worth it. 

Our end products aren't that attractive or flashy, and most of the sites are
intranet-only software anyway so I don't have any sites to provide. I also
don't have any hard numbers to back my statements that I can publish, but I
do know that the projects we sold two years ago would be sold for about
10-20% cheaper today. (And I mean technical development time, not the
overall price to which I have no access.) If we would change back to using
old technologies we would have to add 10-20% to our work estimates. Also the
customer benefits: the bought software is less error prone, easier to
maintain and develop further. 

Tapestry 5 is no silver bullet, you still have to think before you code, but
it does clearly add value. We are 100% committed to Tapestry 5 and will be
using and recommending it for upcoming projects. 

 - Ville 

Ps. What I stated above is my experience in the firm I work for. On top of
that I have developed wholesale trade software system on my own for
orientimport.fi, which makes 7th system that uses T5 that I've build.
(Currently only static website, in about month there should be the real
system online.)

if you rely on onActivate, you surely have the corresponding onPassivate

Ordering of meta tags

[Ville Virtanen]

Hi,

Per Microsoft documentation
(http://msdn.microsoft.com/en-us/library/cc817574.aspx) 
"The X-UA-compatible header is not case sensitive; however, it must appear
in the Web page's header (the HEAD section) before all other elements,
except for the TITLE element and other META elements."

T5 puts some link tags before meta tags, so the META tags wont work..

How can I achieve this?

Re: T5 How to onLoad focus() to textfield in Layout component

[Ville Virtanen]

You can achieve this the T5 way by doing this in the page that contains the
textbox, no need to mess with layout etc. this can even be in a
component...:

  @Environmental
  private RenderSupport renderSupport;

  void setupRender()
  {
renderSupport.addScript("document.getElementById('%s').focus();",
"text1");
  }

Of course, you can do this in afterRender also.

It is all explained in http://tapestry.apache.org/tapestry5/guide/ajax.html

Also, you can inject the textbox using @Component annotation to avoid typing
that id in plain text.

@Component
private TextField text1;
.
.
.
renderSupport.addScript("document.getElementById('%s').focus();",
text1.getClientId());

Re: [T5.1.0.2] / [T5.1.0.3] Combining JavaScript Libraries in IE 6

[Ville Virtanen]

I've experienced this too, and some others in the list.

The underlying issue is that the combining / gzipping dies in the server
side -> the page is loaded but the javascript asset is never delivered to
the browser. However, tapestry includes initialization in the page which
dependes to the asset, which gives error Tapestry does not exist.

Hunt down the stack trace from production and attach it here. Do you also
have tomcat, and develop in windows + deploy to linux?

 - Ville

Ps. We're experiencing this randomly, and for us this is not browser
dependent.

We aren't using any client side validation as all those balloons drove our

Re: More migration issues, 5.0.18 -> 5.1.0.2

[Ville Virtanen]

Hi,

exatly the same problems we were having. I opened Jira issue because of
this:

https://issues.apache.org/jira/browse/TAP5-623

For us the main reason was because we had 



and then


   ${value}
   
  
   


Now with T5.0.18 this worked fine, but now dies in 5.1.0.2 if it is
readmode: (label gets null for parameter) - givin only some T5 internal
stacktrace or the unsupported form of compression..

 Hope this helps,

Re: t5: forwarding in index

[Ville Virtanen]

Two possibilities that I can see:

http://tapestry.apache.org/tapestry5/guide/conf.html and
tapestry.suppress-redirect-from-action-requests. Otherwise T5 will send
redirect to browser and the url in the browser changes.

Other is some url re-write magic.

Re: Binding of Boolean parameter

[Ville Virtanen]

Also the line

writer.write(""+value);

could be to blame?

try something like 

if(value == null) {
  writer.write("null");
} else if (value.booleanValue() == true) {
  writer.write("true");
} else {
  writer.write("false");
}

If it still does not work I suggest that you create JIRA issue and attach
.tml and .java files that replicate this with explanation.

Re: Binding of Boolean parameter

[Ville Virtanen]

Hi,

double check that the boolean is not primitive _anywhere_, as then assigning
null to it would coerse the value to false witch is the default in Java if
it is unknown.

The other option is that the type coersion system in T5 handles null values
incorrectly?

Re: [T5] 5.1.0.1 RC, rendering of some views produces stacktrace

[Ville Virtanen]

Ok, now I had time to look it little closer:

In the particular view I'm generating lazy initialization exp and observe
T5:

The String content is null and thus of course generates npe at that point.
the last encoded string (or one of those) is t-omitted-frame, so it actually
crashes somewhere when rendering the own T5 error page?

Anyway, I don't have the required insight to trace the T5 rendering
mechanisms quickly, and unfortunately just now I don't even have the time to
make a view that reproduces it. (This does not happen under all
circumstances.)

I'll be back when I have time (if it is not solved yet) but atm my work is
too crazy...

 - Ville

Code that crashes: (AbstractMarkupModel, 94)
 public void encodeQuoted(String content, StringBuilder builder)
{
int length = content.length();  <---

Re: 5.0.18 - 5.1.0.1 upgrade problems

[Ville Virtanen]

For the exact same reason we use:

String pageName = someObject.getPageName();
Class pageClass = someObject.getPageClass();
if (pageClass != null) {
pageName = resolver.resolvePageClassNameToPageName(pageClass.getName());
}
pageLink = linkSource.createPageRenderLink(pageName, true, new Object[]{});

where resolver is ComponentClassResolver and linkSource is LinkSource.

Still, you have to use internal services atm :(
