Re: New T5 blog

[Inge Solvoll]

http://tinybits.blogspot.com/2009/10/missing-javascript.html

Started working on AJAX extensions to the builtin Tapestry.js, contributions
from others would be great!

The function for submitting zone forms is quite simple, but also quite
useful I think.

The function for triggering a zone link is the most interesting one. It is
mostly a copy of Tapestry.js code, but modified to enable triggering links
without knowing the event url connected to the link. It is based on Tapestry
putting the actual link url in the href. As of now (5.1.0.5), it does.

My wish for the future is for this function to be built in, so we can call
"Tapestry.triggerZoneLink(linkElement)". And in Tapestry.js, linkZone
function, around line 800, I would like it to look like this:

element.observe("click", function(event)
{
Event.stop(event);

triggerZoneLink(element, url)
});


I would like to hear if anyone thinks this is a bad idea. Because if it is
not, it is really simple to just put it right into the core.

Regards

Inge

It's nice to read some feedback from readers. Thanks!. I'm really happy that
the book made you take a closer look at Tapestry. This is the most wonderful
feadback. This is why I wrote the book. Thus it was worth to write it. :)

URL rewrittng is indeed not covered by the book. It is not possible in
Tapestry to map different methods of a page to different paths. Event

As Thiago already pointed out, you can provide activation methods with
several params.

void onActivate(Tenant tenant, User user, Long id)

Re: Login page - passing context between pages

[DH]

In that case, the context is only useful for Login page, but not the following

Try PageRenderLinkSource#createPageRenderLinkWithContext(String pageName,

This i did as well.
I can get to the the model, fields etc.

The issue/challenge is the fact that only the conduit "really knows" which
fields are empty but it does its job on a per cell basis, if i'm right.
I suppose i could have a look at making sure all fields are in their final
phase before going into the conduit, but
Coming to think about it i have to rephrase my question to:

T5: Removing empty valued columns from grid

[Fermin Da Costa Gomez]

Hi,

I'm looking for a piece of advice/suggestion on the best way to handle the
following.

Using Lucene i generate a searchResult list, in which each searchResult
entry contains a (Lucene)Document. These results wil be displayed in a grid.
Since i cannot determine beforehand which columns (read fields) i will be
receiving i put together my own model and conduit (as per example on the
list somewhere).
So far so good, i'm getting the results i'm looking for.

Final tweak concerns the elimination of the columns without any values.
Obviously this needs to be done prior to rendering but after the results
have been obtained.

My question is twofold:
1. Can i modify the grid model (excluding columns) after its initial
creation, and
2. If so, what would be the best place to do so?

Tia,

Question regarding complex URL rewriting and injecting

[Alexander Reelsen]

Hi,

after reading the new german book on Tapestry I am thinking to take a
closer look at it. It is a very nice and clean structured book, which
can be read quite easily at a rainy weekend. Very well done.

One question I could not figure out from the book is a question
regarding complex url redirects. With complex I mean injecting certain
properties based on the url (like spring 3 supports with its
requestmapping annotation and using expression language like

@RequestMapping(value="/{tenant}/{user}/reservations/{id}",
method=RequestMethod.GET)

Is is possible to do something like this with tapestry as well, like
injecting the specific tenant, user and reservation into the page
(which in this case means the user is dependant from the tenant and
the reservation id from the user)?

My first guess would be to write an own ComponentEventDispatcher for
this, but any help or insight is greatly appreciated.

Thanks and have a nice day!

Re: DDOS emergency button for Tapestry 5?

[Sebastian Hennebrueder]

Depending on the serverity of the attack, you will need to to do this in 
the network layer as higher layers can not sustain much load.

Assuming a Linux based server, this can be done with iptables.

The idea with the author cookie is nice but keep in mind that you need 
to be able to login as well (without cookie). You need to disable DOS 
protection for the login, which leaves a door for DOS.

Even more effective ways are to somehow identify bad requests and cut

Hi Alfie!

Thank you for your thoughts and code. Meanwhile I think you are right,
using a template is not very helpful as it is not easily maintainable
anyway.

I found out what's the problem with the If component that "are only
evaluated once": the If component object is also re-used at every
recursion level, and their "test" parameter is cached, so they will
yield always the same result instead of recalculating it with a new test
value. As this will be the case for most standard components that could
be used to customize the tml, they are not usable in a situation like I
was trying to set up. So, one would have to rewrite all used components
to not cache their parameters which wouldn't be very practical, as it
will make a mess in the tml part.

I already had a tree component using a MarkupWriter that was nearly
identical to the code you sent (thanks again!), the only difference was
the move_next method wasn't recursive but iterative. I think I will make
the component produce / elements with the values of their
"class" attributes configurable via a parameter. That should be enough
of configurability.

Hi,

 


I have been successfully using the CacheControlMarkupRenderer from the
ioko-tapestry-commons

This is a java class that implements the MarkupRendererFilter and
Partial MarkupRendererFilter in order to apply caching headers to pages
served by our application.

 


This is all working wonderfully, however we now have a component which
is returning a StreamResponse object out of the onActivate method of the
component. This of course does not invoke the renderMarkup(MarkupWriter
writer, MarkupRenderer renderer) method on the
CacheControlMarkupRenderer as it is not markup.

 


Is there an equivalent filter we could use that would enable us to set
headers on the Response object but would be applied to both
StreamResponse objects as well as the output from normal components with
markup in a tml file.

Re: Tapestry5 - Helloworld

[Ben Acker]

Howdy!

After reading this I thought of another easy way to do this.

If you have the Maven plugin installed into Eclipse you can create a  
new project and create it directly from the Tapestry Quickstart  
Archetype.


In Eclipse select File - > New -> Other -> Maven -> Maven Project

It will ask you information about your project and then give you a  
list of catalogs from which you can select an archetype.


Add this Catalog to your list: http://tapestry.formos.com/maven-repository

That will give you the T5 quickstart, select it and enter the info for  
your project (Group ID and Artifact ID).


Hopefully this helps! If either of these solutions don't work, let us  
know what your errors are; maybe we can help there.


regards,

Ben

Hi,

When I make my first tapestry project I was struckling with it too.  
But here
are some hints which can be helpfull for you. ( I am using eclipse  
3.5 on

redhat linux)

I presume you understand how to use eclipse and install plugins.

1. Install the mave plugin in eclipse. It can be fond at
http://m2eclipse.sonatype.org/update/
2. Create a Java project
3. Right click the project node and select mave / enable dependancies
management
4. Enter some values and select 'war file' by packaging
5. Add the tapestry5 core jar on the add additional dependancie tab  
page and

click finish

Now create your directory structure

on the src folder click add new folder (you must do it 3 times)

folder 1 : enter main/webpapp/WEB-INF
folder 2 : enter main/java
folder 3 : enter main/resources

add the src/main/java as your sources folder bij properties java
add the src/main/resources as classpath bij properties/java/libraries

create a new java package : for example org.myapp.pages
create under directory src/main/resources new folder with :  
org.myapp.pages


create your Start.tml in the org.myapp.pages folder
create your Start.java in package org.myapp.pages

create new file under webapp/WEB-INF. This file must be web.xml

copy and paste the example of the web.xml from apache tapestry website
located on http://tapestry.apache.org/tapestry5/guide/conf.html

change org.example.myapp to
org.myapp

Save everything

I use mave/package to build a war file and deploy it on tomcat. Some  
people
have jetty running within eclipse but i haven't got this working  
properly.


I hope this is a little help to you

Johan

I tried this code in a page:

@Inject
private HttpServletRequest request;

void onActivate() {
System.out.println(request.getQueryString());
}

It works perfectly.

Re: T5 / Include file ordering

[Gunnar Eketrapp]

Ok!

Since I am including the main css from my border component it will be
included after any page spec. includes.

One cure would be to remove the include of the main css from the border
component and move it into the base page class.

I'll try that ...

Re: Tapestry5 - Helloworld

[tapestryfan]

Hi,

When I make my first tapestry project I was struckling with it too. But here
are some hints which can be helpfull for you. ( I am using eclipse 3.5 on
redhat linux)

I presume you understand how to use eclipse and install plugins.

1. Install the mave plugin in eclipse. It can be fond at
http://m2eclipse.sonatype.org/update/
2. Create a Java project
3. Right click the project node and select mave / enable dependancies
management
4. Enter some values and select 'war file' by packaging
5. Add the tapestry5 core jar on the add additional dependancie tab page and
click finish

Now create your directory structure

on the src folder click add new folder (you must do it 3 times)

folder 1 : enter main/webpapp/WEB-INF
folder 2 : enter main/java
folder 3 : enter main/resources

add the src/main/java as your sources folder bij properties java
add the src/main/resources as classpath bij properties/java/libraries

create a new java package : for example org.myapp.pages
create under directory src/main/resources new folder with : org.myapp.pages

create your Start.tml in the org.myapp.pages folder
create your Start.java in package org.myapp.pages

create new file under webapp/WEB-INF. This file must be web.xml

copy and paste the example of the web.xml from apache tapestry website
located on http://tapestry.apache.org/tapestry5/guide/conf.html

change org.example.myapp to
org.myapp

Save everything

I use mave/package to build a war file and deploy it on tomcat. Some people
have jetty running within eclipse but i haven't got this working properly.

I hope this is a little help to you

regards

Johan

If you still have problems I can sent you an example of a simple tapestry5
project

Re: T5 / Include file ordering

[Martin Reurings]

TBH, a 'component' css-file should never be included before the 'main' 
css, that would make absolutely no sense! The idea suggests that the 
global css is more important than the specific css for a particular 
component!?!?


But, if you really want to do so anyway, @Inject 
org.apache.tapestry5.RenderSupport and in any phase that runs after the 
body is rendered (@AfterBody for instance) user rendersupport to add the 
stylesheet. Not pretty, but it works :) I still remember when I used 
this because there was no annotation for adding stylesheets ;)

Hi!

I am porting an app that have some page specific CSS files.

I added these in the page class files as

RE: Lifecycle of a tapestry request and the MarkupRendererFilter

[Ian Petzer]

Hi,

This is exactly how I am currently setting the headers, however I don't
want to do this on an individual basis for all StreamResponses. 

What I'm looking for a is a filter or similar mechanism that can be used
to post-process all responses irrespective of whether they are
StreamResponse objects or the output from normal components with markup
in a tml file. Essentially a filter like the MarkupRendererFilter that
works on StreamResponses as well

Thanks
Ian

RE: Lifecycle of a tapestry request and the MarkupRendererFilter

[Ian Petzer]

Hi,

We do actually have a load balanced caching system sitting in front our
app server, however we control the caching behaviour by setting headers
on the HTTP responses.

For example in this particular case we need to set:
response.setHeader(CACHE_CONTROL_HEADER,
"no-cache");
response.setHeader(PRAGMA_HEADER,
"No-Cache");

My T5'ed version of the page differs from the HTML designers version and I

So how do I add a page specific CSS include after the border component

Lifecycle of a tapestry request and the MarkupRendererFilter

[Ian Petzer]

Hi,

 

I have been successfully using the CacheControlMarkupRenderer from the
ioko-tapestry-commons
  library.
This is a java class that implements the MarkupRendererFilter and
Partial MarkupRendererFilter in order to apply caching headers to pages
served by our application.

 

This is all working wonderfully, however we now have a component which
is returning a StreamResponse object out of the onActivate method of the
component. This of course does not invoke the renderMarkup(MarkupWriter
writer, MarkupRenderer renderer) method on the
CacheControlMarkupRenderer as it is not markup.

 

Is there an equivalent filter we could use that would enable us to set
headers on the Response object but would be applied to both
StreamResponse objects as well as the output from normal components with
markup in a tml file.

 

Thanks,

Ian

You can get their values injecting Request and then using  
request.getParameter(String parameterName).

Login page - passing context between pages

[shymon]

Some pages of my app are available only to authorized users. When user
enters such a page and is not logged in, appropriate message is shown with
link to login page. After logon user should return to the same page he came
from to login page.

So I pass logical name of restricted page and it's context through context
parameter of pageLink. In login page I use onActivate and onPassivate to
maintain source page context. It works great, but when login is successful I
return source page logical name which causes redirect, but rest of the page
context is null. Simply onPassivate called after onSuccess returns array of
nulls. (Inside onSuccess all variables are correctly set).

How can I store source page context through logon process?

Re: Parameter value was null or contained only whitespace

[Ulrich Stärk]

This is really weird. Somehow Tapestry thinks that the actionlink is referring to a component placed 
on another page than the one that is rendering. And since it thinks the containing page is the index 
page, it converts the page name to the empty string "" which is not allowed as a value for a paramater.


I'm confused.

RE: T5: t:delegate and component recursion emulation

[Alfie Kirkpatrick]

I can't comment in detail on your solution but it looks a bit convoluted
in the TML for my liking. A tree should be a first class component and
in this case I am prepared to do a little more work in the component
class to make it simple and intuitive to use. I wrote an ajax tree a
while back but just put together a non-ajax tree which might give you
some ideas... hope it helps!

The Tree component requires a very simple implementation of TreeModel,
in a similar vein to SelectModel, etc in the tapestry core. This means
that the application can determine where the model actually lives, and
optimise accordingly.

The body of the component defines precisely how each node is rendered.

Most of the complexity is in managing the push/pop between begin render
and after render. Hopefully this is not too confusing, and I actually
think it's pretty succinct given what it's doing.

I just knocked this together and haven't tested it extensively but can't
see why it would exhibit the kind of problems you are seeing with your
solution.

Best regards, Alfie.

On first look I can't see what's wrong here. Could you please post exactly where this happens (the 
error report should give you the name of the component that is in error and a line number inside 
your template).

Link to previous page in ExceptionReport

[Stephan Windmüller]

Hello!

We are using a customized ExceptionReport page to display an error
message to the user. From there we want provide a link to the previous
page so the user can retry the step.

My question is: How do I figure out from where the user came and perhaps
which data was in the activation context?

TIA
 Stephan Windmüller
