Re: How to automatically add mixins to all

[Yohan Yudanara]

Currently my project already have use standard Submit components in all of
its pages.
And there are so many pages.. :)

So I'm looking for an 'automatic' way to add mixins to existing "standard"
submit components on my project.

Thanks..

[Robert Zeigler]

Why don't you create a custom submit component that uses the mixin? Then just 
use your custom component anywhere the standard submit would otherwise be used?

How to automatically add mixins to all

[Yohan Yudanara]

Hi,

I'm planning to use Lenny Primak - Flowlogix's "DisableAfterSubmit" mixins
to all of my submit component. It works great to prevent double submit.

Please give me a clue how to accomplish this, instead of having to copy
paste "mixins="DisableAfterSubmit" to all of submit components on so many
pages?

Thank you..

The PageRenderRequestParameters returned by the first will be passed to  
the next. I haven't looked at the code, but that's what I expect it to do.  
That's what the old URL rewriter code did: the Request returned by one

Re: How to use custom onSubmit handler in form tag?

[Thiago H. de Paula Figueiredo]

Why don't you just add a listener to the 'submit' function of the form  
using Prototype's Element.observe() or the similar function in jQuery?  
Anyway, adding onXXX attributes to attach listeners to HTML elements isn't  
recommended at all.

Don't forget that you can have more than one LinkTransformer. They're  
chained, so you need to ensure they're contributed in the right order.

Be aware of the fact that many classes you will use through T5 will be

You can file a JIRA for Tapestry-IoC supporting annotations in classes.

Activation context sounds fine.  However, I will want to have flexibility to 
add other Activation Contexts values for some of the pages (and not for 
others).  Currently the code in LinkTransformer does something like this (based 
on :

public PageRenderRequestParameters decodePageRenderRequest(Request request)
{

String path = request.getPath();
// do some path munging here
String newPath = someMagic(path);
String pageName = componentClassResolver.canonicalizePageName(newPath);

PageRenderRequestParameters ret = new PageRenderRequestParameters(
pageName, new EmptyEventContext(), false
);
return ret;
}

Let's say there's a page /SomeAccount/profile/SomeOtherVar, where 
"SomeOtherVar" is supposed to go into the activation context as well ... how 
would I handle that?  Do I have the shot of augmenting the activation context 
somewhere on a per-page basis, or do I need to handle all possible Activate 
Context variations in the LinkTransformer?  In other words, is there some chain 
where more processing of the URL is done?

Thanks so much!
Jochen

Hello all,

I am trying to better understand how T5 components work and I would like  
to know what the difference is between @Environmental and @Inject and

They're very, very, very different.

@Inject is one way to get services from the Tapestry-IoC registry.  
@Environmental uses the Environment service, which is used for components  
or pages to pass some information for components inside them.



For instance having a look under the hood of t:checklist, I noticed that
the validation tracker is injected by the @Environmental annotation as
follows:

*@Environmental*
*private ValidationTracker tracker;*


ValidationTracker is not a service.


whereas the javascript support variable is injected by the @Inject
annotation as follows:

*@Inject*
*private JavaScriptSupport javaScriptSupport;*


JavaScriptSupport is a service.

Re: Exception handling in Tomcat 6.0.33

Good thing, that's one way to set things up and I've used it myself
but it only goes half way. The even better idea (if I say so myself)
is to use Tynamo's (and in the future core Tapestry)
tapestry-exceptionpage module for mapping exceptions directly to error
pages (see http://tynamo.org/tapestry-exceptionpage+guide).

HTML doesn't allow nested forms, so you'll probably need to refactor your

the fields (just a suggestion).

Hi Kalle,

yes I managed finally track down the answer after searching through
pages of search results, unfortunately my original search query
included the terms "tomcat", "tapestry" and "error" which produces
reams of result (most of them irrelevant)!

Like you mentioned in your reply I needed to add an error dispatcher
(like example here: http://tapestry.apache.org/error-page-recipe.html)


app
/*
FORWARD
REQUEST
ERROR


I then mapped error codes to tapestry URLs


500
/ExceptionReport


404
/ExceptionReport


Tomcat then started to redirect these error types to my Exception
Report page like Jetty already does. Hopefully this answer will be
found by the next person looking into this issue.

Thanks for the link explaining why the tapestry exception report
filter works in Jetty but not in Tomcat . . .

Question regarding the t:delegate tag in the context of t:checklist component

[Julien Martin]

Hello,

I noticed that a t:delegate is used in order to render the individual
checkboxes of the t:checklist component.

See below:
http://tapestry.apache.org/schema/tapestry_5_3.xsd";>

  * *



Can anyone please briefly explain the logic behind this? How can a simple
t:delegate tag render a full-fledged checkbox?

Regards,

Julien.

Question regarding the internals of t:checklist component..

[Julien Martin]

Hello all,

I am trying to better understand how T5 components work and I would like to
know what the difference is between @Environmental and @Inject and when to
use which in the context of component developpement of course.

For instance having a look under the hood of t:checklist, I noticed that
the validation tracker is injected by the @Environmental annotation as
follows:

*@Environmental*
*private ValidationTracker tracker;*

whereas the javascript support variable is injected by the @Inject
annotation as follows:

*@Inject*
*private JavaScriptSupport javaScriptSupport;*
*
*
Any reason why that is?

Regards,

Julien.

Re: Exception handling in Tomcat 6.0.33

[Kalle Korhonen]

Are you setting an error code to your response? You haven't configured
the filter to handle error dispatches:

app
/*
REQUEST
ERROR


Error handling in Jetty and Tomcat differ, see
http://www.cacoethes.co.uk/blog/software/a-tomcat-gotcha for more
info.

Re: form within a form scenario

[hese]

The reason I want the entire thing enclosed within a form is that I have
other fields along with t:ContactCrud for each row, which have to be
submitted as a whole.

form within a form scenario

[hese]

Hi,

I want to create an ajax grid and do CRUD operations on single rows without
having to post the entire form.  So something like this -



 



ContactCrud is my custom component which in turn deals each row in Edit,
Delete, Create modes.  Each row will have a Edit, Delete icons at the end,
which when clicked will bring up text fields for editing.  When save is
clicked the contents of that row be posted (this is what I cannot do with
AjaxFormLoop, I have to submit the entire form) and that row alone will be
zone updated.

In order to do single row posting, I have a form inside ContactCrud, but I
get an error 'form component cannot embedded with other form components'.

So how should I code this?  Are there any examples like this?

Thanks!

Re: exclude a column from a grid component, by a condition

[Dusko Jovanovski]

Try this:

.tml:



.java:

public String getExcludeColumn(){
if(excludeCondition)
return "somecolumn";
else return null;
}

I didn't test this code, but it should work.

exclude a column from a grid component, by a condition

[Vladimir Bauer]

Good day everybody!

I need to exclude a column from a grid component, by a condition.
t:exclude parameter of a grid component provides ability to exclude any column, 
but with no condition.

So far I have following code, but I think it is a bit ugly, because it is 
repeating same line with grid.

  
  


 


  

Any idea how to do it more properly?

Exception handling in Tomcat 6.0.33

[Brian Long]

Hi all,

I'm sure I'm not the first person to experience this issue but can't
seem to find any answers in the mail archive or on the web. I have an
ExceptionReport page implementing ExceptionReporter so any nasty
surprises like NPE's result in a nice and friendly "We experiencing
technical difficulties" page being presented to the user, this works
fine in jetty but when I deploy my war file to tomcat 6, the
exceptions are not caught by the ExceptionReporter and the stacktrace
is shown to the user?

If anyone know what setting in tomcat needs to change so I can get
this to work as it does in jetty I appreciate it.

Regards, Brian.

Re: URL Rewriting

Hi!


Hi!


I am looking for a clean way to generically rewrite URLs as follows:

Publicly we want to have an account name to be the first part of the  
path in URLs like so:  /SomeAccount/settings/page1.  Since (I believe)  
that in Tapestry I can't bind the first part of the path to a variable,   
I would like to rewrite it to something like this:  
/settings/page1?account=SomeAccount


Why not as the first page activation context value?

How do I pass newly created variable (account) into the  
PageRenderRequestParameters (I guess if knew the Java class from step 1,  
I could check if it implements an interface and if so, typecast it and  
ask the receiving page to generate a link ... but that wouldn't help  
much either.


What do you mean by variable?

It's pretty clear to me how I'd have done it in TS 5.1  
(http://tapestry.apache.org/url-rewriting.html), but URLRewriterRule is  
not supported any more.
Alternatively I could roll my own RequestFilter (like the TimingFilter),  
but it seems there'd have to be a better way?


If you don't want to user LinkTransformer, I'd just copy the URL rewriting  
support from Tapestry 5.1 sources. It's basically a RequestFilter and some  
helper classes. Not much code and it uses nothing that would cause  
problems in 5.3.

Hi all,


Hi!



I have a component with:

 @Parameter(defaultPrefix = BindingConstants.LITERAL, value = "30")
 private int maxResults;

and I also have a subclass component for which I would like to change  
the default the value for 'maxResults' to 10.


When either component (super or sub) is used, i would like the parameter  
to be optional.


Have you tried to provide the default value with a defaultMaxResults()  
method instead of the value attribute of @Parameter? This way, you can  
change the default value using ordinary method override.
