Re: Extra input field after ajax returning MultiZoneUpdate

[Howard Lewis Ship]

I've been tracking this problem; there's a timing issue when Tapestry
adds a hidden field to store the t:formdata; the DOM is being streamed
to characters after the  field is added to the DOM, but before
it is fully configured.  It's deeply tricky stuff.

Hi Peter,

I'm not following the release schedule so I can't say, and I've finished up
with that project now so will be moving on to other things.

Best of luck,

Subject: Re: How do I set up logging with Tapestry 5 and Tomcat?

Good question.

I don't know the answer.

It might have something to do with the fact that I put all my Tapestry 
jars in a common Tomcat lib directory.  It might be different if you put 
them all in your application's lib directory.  That way log4j would only 
start looking for log4j.properties when your application starts, not 
with Tomcat starts.  And it might find it in your WEB-INF/classes directory.

Re: Tapestry 5.1.0.5 Google App Engine

[Alex Kotchnev]

I haven't used the 1.3.2 release, as switching between the point releases
always requires a bit of this unpleasant hacking / setup and the possibility
of new issues. Here are the issues that I remember having to deal with
(historically, not all of them might be an issue right now):

* Replace the security manager - this is only needed to run in the dev
server. There are no issues w/ the app in production. I'm not sure if this
is still needed.
* Replacing the default agent
* An issue w/ javassist - had to switch back to an older version ( 3.9, was
it ? ).

Most of the tips I picked up from Dmitry's blog.

I can check later on and send out my changes that do work w/ 1.3.0 .
Although it does give a warning when I build the app w/ 1.3.0 (because
there's a newer version), the app runs fine when I deploy to GAE (
http://www.zadachite.com)

So a community-driven documentation effort is out of the question unless
we
come up with a system or procedure that complies with ASF rules.



We could just require to sign a CLA for people that want to help out
with documentation. This would mean to give rights to modifiy/create
only to people with CLA. It is the way struts2 handles this issue.

This way people who want to help with documentation would not need

Re: Tapestry 5.1.0.5 Google App Engine

Actually, we're going to use 5.2 (I'm working with Mike Taylor on this)

We'll check the list archives, but a lot of what we're seeing seems  
related on first blush, but isn't related, because we can't get to the  
problem solved in those e-mails (we're not getting the main page  
component looked-up properly, let alone sub-components).


Specifically, findResources() in appengine's dev kit returns an empty  
enumeration for resources in the page path, but returns a non-empty  
enum when executed in a standard jdk.

Hello Tapestry Users,

I’ve been playing around with getting Tapestry 5.1.0.5  working on  
Google
App Engine and I’m having a issue with running it on the DevApp  
server.


Essentially the DevApp server uses a custom class loader to  
simulate the

class loading restrictions imposed by GAE.

It looks as though for some reason this custom class loader is  
preventing

tapestry from being able to locate page classes.  Specifically


org 
.apache 
.tapestry5 
.ioc 
.internal.services.ClassNameLocatorImpl::findClassesWithinPath(String

packagePath)

does the following lookup

Enumeration urls = contextClassLoader.getResources(packagePath);

which when I run it in the GAE DevApp always seems to come back  
empty.


I did some searching around on line and found this issue

http://code.google.com/p/googleappengine/issues/detail?id=1480

which seems suspiciously similar but isn’t quite the behavior I’m  
seeing.
In that case Tapestry was unable to load a component (Loop) that  
was found
in a page.  I don’t even seem to get that far.  The filter never  
finds any
of my page objects and thus never gets as far as looking for the  
components

that they might use.

Has anyone else run into this problem? Any pointers would be much
appreciated.

Mike Taylor

   T 5.1.0.5 still has an issue that prevents it from running out of the

There are a number of T5 apps running in GAE, search this list for more

Re: Documentation Request/Suggestion

[Markus Feindler]

So?? Howard?

So a community-driven documentation effort is out of the question unless we
come up with a system or procedure that complies with ASF rules.



We could just require to sign a CLA for people that want to help out
with documentation. This would mean to give rights to modifiy/create
only to people with CLA. It is the way struts2 handles this issue.

This way people who want to help with documentation would not need
commit rights.

Tapestry 5.1.0.5 Google App Engine

[Michael Taylor]

Hello Tapestry Users,

I’ve been playing around with getting Tapestry 5.1.0.5  working on Google
App Engine and I’m having a issue with running it on the DevApp server.

Essentially the DevApp server uses a custom class loader to simulate the
class loading restrictions imposed by GAE.

It looks as though for some reason this custom class loader is preventing
tapestry from being able to locate page classes.  Specifically

org.apache.tapestry5.ioc.internal.services.ClassNameLocatorImpl::findClassesWithinPath(String
packagePath)

does the following lookup

Enumeration urls = contextClassLoader.getResources(packagePath);

which when I run it in the GAE DevApp always seems to come back empty.

I did some searching around on line and found this issue

http://code.google.com/p/googleappengine/issues/detail?id=1480

which seems suspiciously similar but isn’t quite the behavior I’m seeing.
In that case Tapestry was unable to load a component (Loop) that was found
in a page.  I don’t even seem to get that far.  The filter never finds any
of my page objects and thus never gets as far as looking for the components
that they might use.

Has anyone else run into this problem? Any pointers would be much
appreciated.

Regards,

Mike Taylor

Re: multipage grid with "select all" button

[Norman Franke]

I've actually done things like this for queries and adding a query to  
a list of items to process. I have a checkbox to select all on the  
screen, which is just pure Prototype javascript. I then have a link  
called "add entire query" that re-runs the query and adds the results  
to the queue. Works well and the users find it intuitive.

Why would you want to select something that is not shown? It seems  
quite error-prone and not intuitive to me.
I can't recall any website that does that. In your case, you "select  
all" button must also use AJAX to send a notification to the page so  
it can consider all objects selected.

Re: multipage grid with "select all" button

[Andreas Andreou]

that's the fun part with cookies - you dont have to make them interact during
form submittion - they are sent to the server on every request (even
images, e.t.c.
of course that  also has pitfalls... and explains why most high
traffic sites choose to server resources from a cookieless (sub)domain)!

onchange force page submit

[asianCoolz]

my html code at http://codepaste.net/b6ormu


when onchange on selectbox, this form will be submitted and my pageValidate()
will be called follow by upadteStaff() listener method. I wonder, when such
submission is fired, can onchange='' pass a flag ('selectboxisfired' string)
that i able to capture inside pagevalidate() 'selectboxisfired'?  this will
allow my logic inside pagevalidate to indicate is triggered by selectbox.

Betreff:Getting default validation messages from Messages service



Hello!

Since it seems to be impossible to deactivate validation for single 
buttons of a form component, I want to do validation manually in 
onValidateForm. For this I need the default validation error messages, 
but I cannot receive them through the message service.

messages.get("myTextField-required-message")

is unknown but it should be there. What am I doing wrong?

Re: How to display images in a grid componet?

[啊酒]

No, I didn't put it inside a form.
I set the volatile parameter to true, but just got the error.
And the encoder in a grid has a type of ValueEncoder, which doesn't work
here?

Oups. It seems that I misunderstood the description. What I wanted
was persisting values into hidden form field instead of the session.

It would only work inside a page. If you want to implement it,
implement a PersistentFieldStrategy and contribute it to the
PersistentFieldManager service.

If you do implement it please post a wiki article or something... this
is a classic persistence strategy used heavily by platforms like
ColdFusion (since version 3 and probably earlier), imho it would be a
quite useful.


Sorry, but I did not implement it. Instead I rearranged some persistence
behavior in my pages. Nonetheless I am still looking for a solution
like the above, too.
