Do you mean you are planning on using
https://docs.google.com/viewer

This is googles embedable PDF viewer. It should be relatively simple to
write a tapestry control that uses it.

Re: Google Map Module and JavaScript-only PDF viewer component | GSOC2010

[Alex Kotchnev]

Charith,
   it seems to me that with the Javascript PDF viewer you might be biting
more than you can chew. PDF is not a very pleasant format to deal with, and
in order to view it only in Javascript/HTML you'll need to convert the PDF
to images. I few years ago I was doing something similar, and it was neither
pretty nor pleasant. Alternatively, there seem to be a few ways to convert a
PDF file to flash, but then your component is not going to be "javascript
only".

   Anyway, maybe you could shed some light on how you plan to deal with
this. It also seems like you're kinda new to Tapestry and there's a few
things to learn there as well. Considering that you only have a few short
months for this, it might be wise to pick something more realistic that
doesn't require major inventions in just a couple of months.

Re: Need anchor/link to the fields in Tapestry5 ValidationTracker

[Josh Canfield]

> I need to provide links to the individual fields in errors at the top.

It seems like a case for ValidationDecorator. You can add the  tags for fields with errors. Take a look at the
source for AutofocusValidationDecorator and this old email

http://old.nabble.com/Example-of-overriding-the-default-ValidationDecorator-td26906669s302.html#a26906669


I don't see a way to grab all the Fields in the form, or even just the
fields in error, so you may have to gather that info manually.

Re: simple case for checkboxes & T5

[Josh Canfield]

Hi.

Here is a solution using a patch of the standard checkbox component
that accepts any Object that can be ValueEncoder encoded. I created
stand-in objects and make the assumption that documentFieldDN is
unique and can be used in a set of all documentFieldDN.

You could persist the set as query parameters, or in the browser
cookie or whatever but I'm just sticking the set into the session.

Enjoy!

Josh

Re: Need anchor/link to the fields in Tapestry5 ValidationTracker

Thanks Thiago for quick response.

I will add to JIRA.

You mentioned to use ValidationTracker.get(Field) method to match the error.
That's looks like alternative I can use for now. But the followup question
is, how do I get list of *all* the fields in that form, so I can loop
through them ?

Thanks

What about using String getError(Field field) in ValidationTracker? It's  
not elegant, but at least you can try to match fields to their error  
messages.


I need to follow company's web standards which mandates to provide  
 links to errornous fields.


This seems to be a nice feature to be added to Tapestry itself. Please  
file a JIRA about it.

Subject: Re: Tweaking an AjaxFormLoop


Robert, following your recomendation finally implemented a component  
that

does basically nothing but register itself as a trigger and has an id
assigned by tap as well.

On the client side, I have a global map and a
function triggerRowInjector(triggerId) so that I can inject rows
selectively.

As for the effect thing, you can see that they're hardcoded in the  
function

Tapestry.Initializer.formLoopRemoveLink so I overrode it making them
consistent.

I'm using tapestry 5.1.0.5, so I expect this "solution" to be broken  
by...

5.2, maybe? :P




Robert Zeigler wrote:


That just sounds like you're asking for trouble down the road,
though. ;)
You're effectively relying on implementation details of the  
component.

It'll break if:
  * AjaxFormLoop changes the id of the contained RowInjector  
component

  * You want more than one AjaxFormLoop on the page

I'll grant you that it works... for now. :) And it's the sort of
solution I might put in projects that I write for myself, but not a
solution I would put into a project I write for clients.

It's probably worth submitting a jira for a feature addition to make
this sort of functionality easier/more robust.

There are other ways to do it, although I'm not sure I would call
them
"prettier". :)
AjaxFormLoop places an "AjaxFormLoopContext" object into the
environment when it renders.
You can access this object and add a call to "addAddRowTrigger".
That
part is pretty. The main issue (for you) is that tapestry then
assumes
that the trigger is going to be invoked on the "click" action,  
which

isn't what you want in this case.
There's a way around it, and that's where things get uglier. You  
can

monkey patch tapestry.js to override
Tapestry.Initializer.ajaxFormLoop, and make it behave how you want.
This is typically how I've implemented custom "add row"
functionality.

It might be a nifty change to enable a second form of the
"addAddRowTrigger" that takes, say, a js callback name as a 2nd
argument.  Or perhaps some flag triggering whether the first  
argument

is an id or a callback.  In any event, the initializer could then
check for the appropriate condition, and if the condition is met,  
the
initializer would delegate the setup to the callback, passing in  
the

row injector, rather than assuming a click.  If there's enough
interest in something like this, I would be willing to do the  
work to

add it to the framework (the exact api would need to be worked out,
though).


The same question could apply to any client-side ajax behavior,  
like

refreshing zones. Is there any way to do it programmatically via
javascript?



The best answer here is to take a look for yourself through  
(mainly)

the tapestry.js file.
But, yes, you can refresh zones in non-default ways; the trick (as
with AjaxFormLoop above) is getting a handle to the runtime js
objects.

Another thing: the javascript effect displayed when a row is  
added/

removed
behaves in a somewhat weird fashi

simple case for checkboxes & T5

[jaques robert]

Hello,


I've got some problemes with checkbox & T5 for a while. I'd just like to 
display a page which could contains some checkbox, then submit this page in 
order to treat the various item corresponding to the ticked checkbox then 
redirect to the same page with the same checkbox ticked. It is simple with JSP 
however seems complicated to me to realize with T5




    

        

                                    

                                            

                                        

                                  

        ...



Howard Lewis Ship advise to use the http request without using t5 component in 
this cas. That was I've done. However for the display when returning to this 
page after submission documentField.checked is always to false

Perhaps I'm missing something moreover I think I'm making a "usine à gaz".


On the onActivate() I've got :

        _exportNameForModifcation = exportNameForModification;

        System.out.println("_exportNameForModifcation : " +
_exportNameForModifcation);

        documentFieldAlreadyTicked =
getExportService().getDocumentFields(exportNameForModification);

        

        HttpServletRequest req = requestGlobals.getHTTPServletRequest();

        List selectedDocumentFields = new
LinkedList();

  

on the onSuccess() :

        HttpServletRequest req = requestGlobals.getHTTPServletRequest();

        String[] exportToCreate =
req.getParameterValues("selectedDocumentFields");

                

        System.out.println("exportToCreate : " + exportToCreate);   
    

        _formFieldsToCreate = Arrays.asList(exportToCreate);

        

        getExportService().modifyExportProfil(_profilName, _language,
_formFieldsToCreate);

        

        //return this;

        return null;


on the getDocumentField()



public ExportDocumentField getDocumentField() {

        System.out.println("_documentField : " + _documentField);

        if (documentFieldAlreadyTicked.contains(_documentField)) {

            _documentField.setChecked("true");

            System.out.println(documentFieldAlreadyTicked + " contains
" + _documentField);

        }

        else {

            System.out.println(documentFieldAlreadyTicked + " does not
contains " + _documentField);

            _documentField.setChecked(null);

        }

        

        return _documentField;

    }


It sux cause getDocumentField() is called much more times than the item 
displayed. Is it the good way to go ?


If I use a t:checkbox component I see that there isn't a selected property as 
in T3 for knowing which one is 
selected.http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Checkbox.html)


Can you help me resolve this case ?

Mondes.

Robert, following your recomendation finally implemented a component that
does basically nothing but register itself as a trigger and has an id
assigned by tap as well.

On the client side, I have a global map and a
function triggerRowInjector(triggerId) so that I can inject rows
selectively.

As for the effect thing, you can see that they're hardcoded in the function
Tapestry.Initializer.formLoopRemoveLink so I overrode it making them
consistent.

I'm using tapestry 5.1.0.5, so I expect this "solution" to be broken by...
5.2, maybe? :P

That's very much what I have, and it works for me.
eg:

Get final ouput of page rendering

[iapilgrim]

Hi all,
I'd like to get the final output of Page ( to cache for example)
I do this by using 
public static PageResponseRenderer decoratePageResponseRenderer(
   ... grabs // content here
}
But at this phase, I still miss some css and js files that included in each
component in page.

So my question is:
Is there another way to get final content ?

Thanks,
Van

using other namespaces

[Kath Ede]

how is it possible to integrate other namespaces than the tapestry-ns (t:) in 
tapestry5?

we have this:
http://tapestry.apache.org/schema/tapestry_5_1_0.xsd"; 
xmlns:fb="http://www.facebook.com/2008/fbml"; >

and in out page we want to include this:


when we try to run that, we get an exception.

has anybody successfully integrated a facebook-connect button into a tapestry 
project?

thanks in advance

Re: Exception with T5 & checkbox

[jaques robert]

Another question is how to traduce : 


to tapestry component ?

I've already tried that but IE & FF when meeting checked="" or 
checked="checked" are considerating that the checkbox are checked :( ...

I'm using this html component because if I use the T5 component, I've got type 
coercion error (see my other posts inside this ML)

So the idea is to use a  to display checked or not. However the test to use 
can be of that sort : 
 ?

The ${documentField.checked} part is valid HTML but not valid XML, and Tapestry 
templates must be valid XML even when outputting HTML. If you really want not 
to use the Checkbox component, use checked="${checked}" and add this method to 
your class:

public String getChecked() {
    return documentField.checked ? "checked" : "";
}
