RE: How to pass parameters between Page and component

[Firas Adiler]

Hi,

It should be more like:
  component id=articleComp type=ArticleComp
binding name=articleId value=ognl:articleId/  
/component

In your ArticleComp you access the 'articleId' parameter like this:
IBinding iBinding = getBinding(articleId);
String articleId = (String) iBinding.getObject(articleId);

Regards,

/Firas

Subject: How to pass parameters between Page and component


Hi, I have a (hopefully) easy question. I have My index.page where I use
some components. One of them needs a parameter articleId passed to it from
my index.java file where I have a getArticleId().
I thaugh that I declared a parameter in the .page file and then use the same
parameter in my binding tag in the component like this:

   parameter name=articleId required=yes/

component id=articleComp type=ArticleComp
binding name=value value=articleId/   
/component

but I get an error when I do this.

Unexpected element parameter within page-specification.

So my question is: How do I pass my articleId from my index.java to my
custom component?

Thanks
Jacob

RE: How to observe property binding events

[Epstein, Ezra]

OK, let's get to brass tacks.

I have some derived values that are somewhat expensive to compute so I compute 
them once per request/response cycle and then they're in local instance 
variables (non-persisted).

The particular component in question (with the semi-expensive derived values) 
is used inside a loop and so may appear multiple times on a page.  By default 
the first time I use the component I compute the value and then display from 
that computed value...  The 2nd, 3rd, etc instance of those component on the 
page is actually the exact same Java instance and so the computed/derived ivar 
is still set.  I've added a hack that records an original property value when 
the derived ivar is computed and if the original and current property values 
don't match I reset the derived ivar.  It works, but it a total hack.  

The common way I'd imagine doing it is to listen to when the property 
(parameter) is set by Tapestry.  But now that I've lain out the use case maybe 
some knows the right way to do this in Tapestry.


Thanks, 

Ezra Epstein

There's also the org.apache.tapestry.event.ChangeObserver interface, though 
this is currently only used by the services in tapestry.persist to observe page 
property changes when they are being managed via a particular persistence 
strategy. (like session/client/etc..)

~Maybe~ it's an oversight, and maybe not..I guess that depends on what/why you 
are trying to do. You'll find that there is very little in the framework that 
wasn't put there for an actual need, so adding in support for things that no 
one has needed yet doesn't seem to fall in line with sound design.
(imho of course..)

If you can outline why you need this, and exactly what properties/conditions 
you'd want to observe we might be able to work something out...A general 
anything is harder to understand / design around.

There is no such thing as a parameter property listener because parameters 
have no meaning in the context of something taking a parameter...There has to 
be a source for that parameter value (usually a page ) somewhere.

 Yes, but the usefulness of my answer largely depends on how 
 clever/efficient you are trying to be doing it.

 Now, there is IBinding. The one object to bind them all ;)

 If you work your way down the type hierarchy you'll find 
 AbstractBinding, which holds the method you care about most - 
 setObject. This will be called by tapestry when managing all of the page 
 properties automagically
 for you.

 Some of the magic happens in (for your exact case at least) 
 org.apache.tapestry.enhance.ParameterPropertyWorker.

 The other half of the work happens in each specific binding 
 implementation that will handle these set/get object calls..(Like ognl 
 bindings, etc..)

 I'm not sure where you are going with this but I guess you could use 
 the hivemind chain of command service sort of configuration (like I 
 did for org.apache.tapestry.services.ComponentRenderWorker ) to 
 generically call a single interface method for a hivemind 
 configuration point...Then you can contribute as many workers into the 
 chain you like if you decide that you have more than one use for it.

 Again...Not knowing what you are doing - and taking the exact 
 parameters given I'd probably extend and override the default 
 ParameterPropertyWorker (a hivemind service, so replacing it inline 
 with what Tapestry does already should be easy )  and just  override 
 whatever section of code I needed to in that implementation to inject + call 
 my service reference.

 It may look a little complicated in there at first, but the whole 
 org.apache.tapestry.enhance package is filled with lots of different 
 enhancement works - and most of them inject a service into the object 
 they work on...So finding an easier to follow

Also, that title should have been parameter binding events not (generic) 
property.  The situation I have occurs when the framework sets the parameter on 
a Component.

Re: How to observe property binding events

[andyhot]

Why store them in local variables?
Store it in the current request cycle...
First do a cycle.getAttribute(myexpensivevar) if that returns null, do
the computations and store
the result back cycle.setAttribute(myexpensivevar,obj);

See
http://tapestry.apache.org/tapestry4/tapestry/apidocs/org/apache/tapestry/IRequestCycle.html

Accessing HiveMind Registry

[Edoardo Campagnano]

Hi to all,

I've got a small prioblem with HiveMind. I wrote a small Service but I must
use from a class taht is outside a Tapestry component and can't be declared
abstract. I need something like in the HiveMind manual:

 

(from the HiveMind home page)
.
Registry registry = RegistryBuilder.constructDefaultRegistry();
MyService service = (MyService)
registry.getService(com.mypackage.MyService, MyService.class);

.

 

The key is access the Registry but in this way it throws an exception. I'
don't know how but I'm sure it is possible

Re: Accessing HiveMind Registry

[Ron Piterman]

One way would be to create a factory for instances of this class in
hivemind, and inject any services you need to it.

Another way would be to get the registry instance tapestry uses, which
is stored as a context attribute. see the ApplicationServlet code.

Validation questions: components and messages

[Dave Rathnow]

I have written a component that contains text fields that need to be validated
when a page is submitted but I can't figure out how component validation
hooks into Tapestry's validation framework.  I can access my validation delegate
in my page component but how can I get the validation delegate from my
component?

Also, is there an easy way to get the individual error messages from the
validation delegate?  I want to put individual validation errors messages
next to each field rather than have a single message at the top of the page
and then ** beside each of the errored field.

Thanks,

I've found the ServiceLink component indispensable in this regard. You
can
create a simple little arbitrary engine service without the hassle of
creating new link components to run it...So..In your case you could:

Define a new engine service that serves files to people in such a way that
it'll correctly invoke their browsers application content handling type -
or
download if none is found...(Ie setting response type , etc..)

Then use a simple ServiceLink to pass in what you want to give the
service,
which is presumably a local asset you have defined.

You use per Form one instance of validation delegate. It tracks the
validation errors which the components report. This happends from
itself, you just need to define the validators on the fields.

 
 Also, is there an easy way to get the individual error messages from the
 validation delegate?  I want to put individual validation errors messages
 next to each field rather than have a single message at the top of the page

In such a case you need to create your own class, extending the standard
validation delegate. There are methods which allow the delegate to hook
up into the rendering of fields and their labels, so you can do just
what you described.

We also wrote our own validation delegate with nice error-icons.

Problems with css tag in custom components

[jake123]

Hi, 
I have some problems with my custom components. Each of the components have
their own CSS so I need to insert a tag like this for the component:
link jwcid=cssLink href=/default/css/topbar.css rel=stylesheet
type=text/css /
this tag will not end up in the head tag but actually in the body of the
html. 

The results come out like this (disregard the white spaces in the biginning
and the end): 
 l t ; link href=/default/css/topbar.css type=text/css rel=stylesheet
/  g t ;

So, the problem is that tapestry converts the html symbols instead of
serving html tags. It also does the same for a image tags.

I have in my java code  this method:
public String getCssLink() {
/* Get the link for the right css */
String templateName = getSessionUserInfo().getTemplateName();
return link href=\/ + templateName + /css/topbar.css\
type=\text/css\ rel=\stylesheet\ /;
}

Is this the wrong approach? If so, how should I do this instead?

Thanks
Jacob

For tap 3.0.x and 4.0.x assuming you use the Insert component,

set the raw attribute to true.

 haven't found Tapestry to be the issue, but the rest of the app...

For simple expressions, try tapestry-prop, which compiles into java
bytecode instead of reflection that ognl relies on.

Re: Validation questions: components and messages

[Ron Piterman]

Yes - you can do much with the delegate :)
BTW - consider using CSS for this instead of adding elements , it might
be more elegant and easier to maintain...

 In such a case you need to create your own class, extending the standard
 validation delegate. There are methods which allow the delegate to hook
 up into the rendering of fields and their labels, so you can do just
 what you described.
 
 We also wrote our own validation delegate with nice error-icons.
 Somehow like this:
 
 public class MyValidationDelegate extends ValidationDelegate {
 
public void writeAttributes(IMarkupWriter writer, IRequestCycle
 cycle, IFormComponent component, IValidator validator) {
if (isInError())
writer.attribute(class, validationerror);
}
 
public void writeSuffix(IMarkupWriter writer, IRequestCycle cycle,
 IFormComponent component, IValidator validator) {
if (isInError()) {
writer.print( );
writer.beginEmpty(img);
writer.attribute(src, warning_small.gif);
}
}
 
public void writeLabelPrefix(IFormComponent component,
 IMarkupWriter writer, IRequestCycle cycle) {
if (isInError(component)) {
writer.begin(span);
writer.attribute(class, label-error);
}
}
 
public void writeLabelSuffix(IFormComponent component,
 IMarkupWriter writer, IRequestCycle cycle) {
if (isInError(component))
writer.end(); // span
}
 }

 before getting page from the pool. Any ideas where and how should
 stateless applications locale be set?

 P.S. language as GET parameter is in requirements, so there's no

Setting locale based on querystring

[Malin Ljungh]

I've seen this issue before on this list but not seen any satisfying
solution.

This is my problem:
Based on the querystring to one of my tap pages (it is a link from outside)
I derive the locale that I wan't to use to display the requested page.
In other part of my app I use a DirectLink and a listener to switch locale:

getPage().getEngine().setLocale(new Locale(language));
getPage().getRequestCycle().cleanup();
throw new PageRedirectException(this.getPage());

and that works fine! Though, if I put the same code in my page mentioned
earlier, in the pageBeginRender listener method, I will get an exception
page telling that a PageRedirectException has occurred.
So, it doesn't work (why?)

How should it be done?

Any help highly appreciated.

RE: How to observe property binding events

[Epstein, Ezra]

That's the opposite of the functionality I want.  These are not PER request.  
They are per instance of a component.  Thus true instance variables are the way 
to go. Tapestry recycles Components and it seems that within a request the same 
component is re-used but not cleared (ivars reset) even though it is 
re-parametrized.  So, I don't think request vars would work.

Why store them in local variables?
Store it in the current request cycle...
First do a cycle.getAttribute(myexpensivevar) if that returns null, do the 
computations and store the result back cycle.setAttribute(myexpensivevar,obj);

See
http://tapestry.apache.org/tapestry4/tapestry/apidocs/org/apache/tapestry/IRequestCycle.html


Epstein, Ezra wrote:
 OK, let's get to brass tacks.

 I have some derived values that are somewhat expensive to compute so I 
 compute them once per request/response cycle and then they're in local 
 instance variables (non-persisted).

 The particular component in question (with the semi-expensive derived values) 
 is used inside a loop and so may appear multiple times on a page.  By default 
 the first time I use the component I compute the value and then display from 
 that computed value...  The 2nd, 3rd, etc instance of those component on the 
 page is actually the exact same Java instance and so the computed/derived 
 ivar is still set.  I've added a hack that records an original property value 
 when the derived ivar is computed and if the original and current property 
 values don't match I reset the derived ivar.  It works, but it a total hack.  

 The common way I'd imagine doing it is to listen to when the property 
 (parameter) is set by Tapestry.  But now that I've lain out the use case 
 maybe some knows the right way to do this in Tapestry.

 There's also the org.apache.tapestry.event.ChangeObserver interface, 
 though this is currently only used by the services in tapestry.persist 
 to observe page property changes when they are being managed via a 
 particular persistence strategy. (like session/client/etc..)

 ~Maybe~ it's an oversight, and maybe not..I guess that depends on what/why 
 you are trying to do. You'll find that there is very little in the framework 
 that wasn't put there for an actual need, so adding in support for things 
 that no one has needed yet doesn't seem to fall in line with sound design.
 (imho of course..)

 If you can outline why you need this, and exactly what properties/conditions 
 you'd want to observe we might be able to work something out...A general 
 anything is harder to understand / design around.

 There is no such thing as a parameter property listener because parameters 
 have no meaning in the context of something taking a parameter...There has to 
 be a source for that parameter value (usually a page ) somewhere.

 Hi Jesse,

 Thanks for that reply.

 If I read it correctly, it sounds, simply, like the framework is 
 missing this feature.  It's a pretty common thing to ask for listener 
 call-backs on framework events.  (Listener here in the generic 
 sense rather than the way tapestry uses the term for direct-link 
 targets.) In short, this sounds like a design over-sight.  It's 
 common when beans are bound to be able to receive a call-back -- 
 Hibernate, for example, offers this.  So much of Tapestry seems 
 automagic I'm surprised that there's no way to register to be informed of 
 the events as they occur.

 If Howard's reading this perhaps he has a better perspective that he 
 may offer.

 Yes, but the usefulness of my answer largely depends on how 
 clever/efficient you are trying to be doing it.

 Now, there is IBinding. The one object to bind them all ;)

 If you work your way down the type hierarchy you'll find 
 AbstractBinding, which holds the method you care about most - 
 setObject. This will be called by tapestry when managing all of the page 
 properties automagically
 for you.

 Some of the magic happens in (for your exact case at least) 
 org.apache.tapestry.enhance.ParameterPropertyWorker.

 The other half of the work happens in each specific binding 
 implementation that will handle these set/get object calls..(Like 
 ognl bindings, etc..)

 I'm not sure where you are

Thanks for the input Matthew. I especially like enhancements that make

Or, if you had a suggestion for a DatePicker that you think works

DirectLink in Abstract Component

[jake123]

Hi,
I have a menu component that extends AbstractComponent. It seems that my
DirectLinks in the menu component does not work. I have 4 different Listener
methods and I have injected the pages that they should go to. If I add
sysout:s to se if I end upp in the listener methods nothing happens. I have
done this:

in MenuComp.java:

public abstract class MenuSystem extends AbstractComponent {

/*  */
@InjectState(sessionuserinfo)
public abstract SessionUserInfo getSessionUserInfo();

@InjectPage(HomeAction)
public abstract HomeAction getHomePage();

@InjectPage(ContactUsPage)
public abstract ContactUsPage getContactUsPage();

@InjectPage(ArticlePage)
public abstract ArticlePage getArticlePage();

@InjectPage(ArticleListPage)
public abstract ArticleListPage getArticleListPage();

@Override
protected void renderComponent(IMarkupWriter writer, IRequestCycle 
cycle) {
.
writer.begin(a);
writer.attribute(jwcid, @DirectLink);
writer.attribute(listener, listener:onClickDirectLinkHomePage );
writer.attribute(onmouseover, hideAllButThis('none', 'none'););
writer.attribute(href, #);
writer.begin(span);
writer.print(menu.getName());
writer.end(); // end span
writer.end(); // end a

   }

   public HomeAction onClickDirectLinkHomePage() {
return getHomePage();
}

public ContactUsPage onClickDirectLinkContactUsPage() {
return getContactUsPage();
}

public ArticleListPage onClickDirectLinkArticleListPage(Long menuId) {
getArticleListPage().setMenuId(menuId);
return getArticleListPage();
}

public ArticlePage onClickDirectLinkArticlePage(Long articleId) {
getArticlePage().setArticleId(articleId);
return getArticlePage();
}

}



The menu component is rendering correctly, but nothing happens when I try to
click on my DirectLinks. Hopefully I just missed something small, but I cant
see it...

Thanks
Jacob

A dynamic css emitter like the @Script component

[Josh Long]

http://www.madskristensen.dk/blog/CommentView,guid,9b4acb83-3ab4-45a0-be95-b4279f4da7d1.aspx

The preceeding link is a an implementation (not my own, obviously) of
a ASP.NET engine-service which renders your css based on scripted
inputs.

I know there's a lot to be said for x-platform CSS, but the truth is
we don't really have that, and even where it's 99% there, I can think
of a few cases where being able to determine a value on the server and
have it consistantly used (say the width of an image and the width of
its container, or an advert, or even storing preferences for
font-sizes, etc.) would be invaluable.

If, in a month, I were to try and cobble something like that together
which allowed scripting of css files (of course, I'd do my best to
adhere to the .script template mechanism and ognl instead of using
Java (or C# heh) inline), would anybody be receptive to it?

Any feedback that you might offer? Anything I might need to know? If I
setup the same duo of CSS component and service as Script currently
enjoys, would that work?

In a related note, are there are engines in java which read CSS? Does
the @Script component at point read/validate the JavaScript it's
emitting using Rhino?  The beauty of such a service for the .css woudl
of course be the chance to cache/and compress the css while we're in
there, in essence yeilding css files which are parameterized and
compressed. I know white space can be an issue in CSS, though, so I
was wondering how such transformatiosn might be accomplished?

Thanks in advance for any feedback,
Josh

Tapestry page (and other) event listeners

[Epstein, Ezra]

The common idiom for listener registration (Swing, Java Beans, etc.) is that 
the remove() method returns the listener and the add() method only adds a 
listener if it's not already listening.  Tapestry's impl follows neither of 
these approaches.  Is there a reason for the naïve implementation of the 
methods like 

void addPageBeginRenderListener(PageBeginRenderListener listener)

?  A LinkedHashSet() would give the ordering of the current ArrayList 
implementation plus the uniquing properties of a set...

I'm not sure what the requirements are wrt properties and specific users.

I've done similar things on a per request basis via doing something like:

public abstract int getProp();
public abstract void setProp(int value);

public int getComplicatedValue()
{
  if(getProp() == -1) {
 // do something complicated
setProp(newVal);
  }

 return getProp();
}

The idea being that the heavy operation will only happen once for that 
request/response cycle.

This all changes if you want it to be done for all users ? You can do that as 
well I suppose but I think I probably need more clarification on who the 
properties are supposed to be exposed to/etc..

  I've done similar things on a per request basis via doing 
  something
  like:
 
  public abstract int getProp();
  public abstract void setProp(int value);
 
  public int getComplicatedValue()
  {
if(getProp() == -1) {
   // do something complicated
  setProp(newVal);
}
 
  return getProp();
  }
 
  The idea being that the heavy operation will only happen once for 
  that request/response cycle.
 
  This all changes if you want it to be done for all users ? You 
  can do that as well I suppose but I think I probably need more 
  clarification on who the properties are supposed to be exposed
 to/etc..

   That's the opposite of the functionality I want.  These are not 
   PER request.  They are per instance of a component.  Thus true 
   instance variables are the way to go. Tapestry recycles 
   Components and it seems that within a request the same component 
   is re-used but not cleared (ivars reset) even though it is 
   re-parametrized.  So, I don't think request vars would work.

   Why store them in local variables?
   Store it in the current request cycle...
   First do a cycle.getAttribute(myexpensivevar) if that returns 
   null, do the computations and store the result back 
   cycle.setAttribute (myexpensivevar,obj);

OK, let's get to brass tacks.
   
I have some derived values that are somewhat expensive to

   compute them once per request/response cycle and then they're in

The particular component in question (with the semi-expensive

Instructions for building 4.1

[Ryan Cuprak]

Hello,
 Just curious if there are instructions for building Tapestry 4.1  
from source/version control?
 I did find http://tapestry.apache.org/tapestry4.1/download.html but  
I am not quiet sure what I need setup. I have begun looking into  
maven but it is a bit tangential to tapestry 4.1.


Thanks,

I believe all you need to do is this after installing maven:

mvn

in the main tapestry directory.  ;)
