RE: T4.1.6 Troubles with accessing bindings from async listener method
I solved it with passing the index of an item in collection as a direct link
parameter which then updates component's parameter. Then the client of this
component (usually page) access the object from collection with updated
index. Thanks!

When the direct link is triggered, your listener is called.
I don't think the source parameter will be bound since there's no page
rendering (or rewinding) happening - just the listener method getting
called.
Anyway, you have a few options here:
- Persist the list into the session.
- or, just add the item to the direct link (it needs to be
serializable or you need
to write a custom DataSqueezer for it) using:
binding name=parameters value=ognl:value /

Subject: T4.1.6 Troubles with accessing bindings from async listener
method
Hi, all!
I have problems with understanding how bindings work in Tapestry when they
are accessed from async listener.
I'm trying to build a List component which takes parameters source, value
and selectedValue. It renders source and updates value as For component.
I would like that users can select one row in List component and that some
components on page are updated and that they use this updated selected
object value.
Component specification is:
component-specification class=org.tapestry.example.ListComponent
parameter name=source /
parameter name=value /
parameter name=selectedValue /
parameter name=updateComponents /
component id=iterator type=For
inherited-binding parameter-name=source name=source /
inherited-binding parameter-name=value name=value /
/component
component id=selectLink type=DirectLink
binding name=listener value=listener:changeSelecedObject
/
binding name=parameters
value=ognl:components.get('iterator').index /
/component
/component-specification
Java class:
package org.tapestry.example;
public abstract class ListComponent extends BaseComponents{
public void changeSelectedObject(IRequestCycle cycle) {
int indexOfRow =
(Integer)cycle.getListenerParameters[0];
Object value = this.getSource().get(indexOfRow);
- THIS LINE THROWS IndexOutOfBoundsException since
this.getSource() returns empty list.
this.setSelectedValue(value);
for (String compId : this.getUpdateComponents) {
cycle.getResponseBuilder().updateComponent(compId);
}
}
public abstract void getSource(); // Biding accessor for Source parameter
public abstract void getUpdateComponents(); //Biding accessor for Update
Components parameter
public abstract void setSelectedValue(Object objValue);
}
I wonder why I'm getting empty list in listener method. Parameter source
was
bound with list with 2 items in it and I got there empty list.
Any help is appreciated.
Regards,
Marko

T5: how to eval 'canned' expansions (stored in db)?
I have a page showing different blocks (ala myYahoo , netvibes, etc) .
Each block is a different component.
One of these components gets it's content from a database and writes it in
the BeginRender() - phase. The content to store in the database is some
html possibly with tapestry expansions. E.g: today is: #foo
${dateAsString} or something. (The database route is the way to go for me
in this scenario, as content is not known at design-time)
Is there a way to evaluate the expansions in the the html in the
component.beginRender phase and render the result?
This would be pretty powerful stuff.
Thanks,
Geert-Jan

This limitation has been a blocker for me too. All form components need to
be enclosed by a form in the same template.
I guess you need to use some other strategy, for example by subclassing the
select component? I would like to se some nice suggestions on this, as this

You can inject the PropertyConduitSource service (it is public). You
can obtain PropertyConduits, which are the compiled versions of
property expressions (as used by parameter bindings).
The PCS caches the result, so it's reasonable to pass an a class and
an expression, get back a PC, and discard it.

ComponentResources includes a method, discardPersistentFieldChanges(), for this purpose ... the trick is to know when to invoke it. In Tapestry 5.2, there's a new lifecycle method, pageReset(), that your pages/components can implement. It is invoked during page render requests, when the active page changes.

Re: How to return a t:select component without a form (T5.1.05)
It's not quite true, but close enough. All form components have to have a FormSupport environmental object available when they render. So you can have form fields that are in blocks on non-rendering pages and pull those blocks into the rendering page and everything works fine. The problem occurs when you do an ajax request where you want to update some small portion of the page, itself contained within a form, with some form-based content. In that case, the naive solution will fail. Eg: t:form ... t:zone ...!-- some zone to be updated via ajax, within the form; we want it to render form fields. --/t:zone ... /t:form When you update the zone with some form-field-containing content, you'll get a failure because the form fields won't have a FormSupport object available to them in the environment. This is what, eg, the FormInjector component tries to solve. Unfortunately, it seems geared toward use with, eg, AjaxFormLoop. In any event, it's a bit unwieldy to use on its own.

Re: How to clear an @Persist-ed value in a component?
2010/1/21 Stephan Windmüller stephan.windmuel...@cs.tu-dortmund.de: Am 21.01.2010 09:04, Hilco Wijbenga wrote: So how would you suggest I store data that I only need in a component? That depends on what you want to do with the data and where you need it. The component would consist of a dynamic set of radiogroups and checkboxes. While the user just sets up his choices I wanted to let the component take care of remembering those choices (as this is all temporary and the page doesn't need to know about it). Once completely done a separate submit would yield an object (for the page) based on those choices and the component would be done. I'm already using the activation context (not for this component) but the component has a fair number of fields and this is only the first component. I'm afraid I would be overloading the activation context. (It's not a lot of data, just a lot of fields.) Perhaps you could describe what sort of component this is, what the users does with it and what you do with the data. See above. I'm not using a database so all data needs to be in either the session, the URL, or in (the server's) memory (other than the session). So you want to store all the data which the user generates in his session? :-) I guess there's not really another option. I may be making things too complicated. What would be the most economical and scalable way to store up to a few hundred small fields (tiny integers and single characters only)? I could probably work out a way to compress it all into a single string which I could store in the activation context. On one page I use an approach like this. I want the user to be able to undo the settings until he leaves the page, so I store all previous steps in a Java List, convert it to compressed XML and store it in a hidden field. This is rather ugly but the only way I could think of. Yes, exactly.

Re: How to clear an @Persist-ed value in a component?
2010/1/21 Howard Lewis Ship hls...@gmail.com: In Tapestry 5.2, there's a new lifecycle method, pageReset(), that your pages/components can implement. It is invoked during page render requests, when the active page changes. See the nightly documentation for details. That sounds very useful. I'll have a look at that once 5.2 is out. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Dynamicly Created Checkboxes
Hi all,
I am trying to get the submit results of a dynamic set of checkboxes
and I'm stumped.
html xmlns:t=http://tapestry.apache.org/schema/tapestry_5_1_0.xsd;
body
t:form
t:loop source=list value=item
t:checkbox t:id=checkbox t:value=checkbox
t:context=item/${item}br/
/t:loop
t:submit/
/t:form
/body
/html
public class Test {
private final String[] list = new String[] { Abc, Defg, Hijkl, Mno };
@Property private String item;
@Property private boolean checkbox;
public String[] getList() {
return list;
}
}
If I simply add onSuccess() I only get the result for Mno. Adding
one or more parameters (for item and checkbox) doesn't seem to work. I
tried various other methods and combinations but nothing seems to do
the trick.
How do I do this?
Cheers,

Re: T5: some automagical way to export versioned assets to CDN?
You can override AssetPathConverter service. example: http://code.google.com/p/corner/source/browse/corner3/trunk/src/main/java/corner/asset/services/impl/CDNAssetPathConverterImpl.java 2010/1/22 britske gbr...@gmail.com Versioning in Tapestry is really easy. Just increment the version-nr in appModule and you're set. However, I'd like my assets to live on a CDN. (Amazon S3 + cloudfront) . For this to work (along with versioning) I would have to do 2 conceptual things: 1. export assets to a specific s3 bucket linked to cloudfront. 2. point html-code to correct path. To do this manually I'd have to: - up the version in appmodule by hand. - create a new s3 bucket by hand (with the version-nr encoded in it) - ? copy/ move the versioned assets-directory created by Tapestry to the newly created S3- bucket ( I assume it is created on-the-fly on run-time and are saved to disk? - point html-code to the new correct path. I assume I can code this once, bc. I must be able to access the versionnr, and along with the static s3-path be able to create the path to the newly created s3-bucket. All this is possible, but I would like it to be automated. Is this already possible (with some minor tweaking) If not, where would I start looking to automate this? any pointers highly appreciated.

Re: Dynamicly Created Checkboxes
I think you should write own component to support that.

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