I know that. But it doesn't have the same effect per the HTTP spec and I'm orthodox.

T5: Keep case (upper or lower) in page names and links
I've got a page called "Login" (first char is uppercase). There's a form on it. When it posts back it takes me to "login" (lowercase) which Tapestry treats as the same being case-insensitive. That's fine for now, but I want to preserve case for the end user. How do I tell Tapestry to send the user to "Login" and not "login"?

T5 turn off form validation
How do I turn off form tracker / validation. Not just client side but the whole thing? Can I just use a plain HTML (not Tap) form?
T5 Sending a 302 redirect off-site from within a Form handler
I've got a simple form and an onSubmit() method. When the form
submission succeeds I want to redirect to another site (full URL) but
can't figure out how to do that.
I've tried:
@Inject
@Service("Response")
private Response tapestryResponse;
void onSubmit() {
...
tapestryResponse.sendRedirect(offsiteUrlString);
...
}
No luck. Also tried:
@Inject
//@Service("RequestGlobals")
private RequestGlobals requestGlobals;
void onSubmit() {
...
requestGlobals.getHTTPServletResponse().sendRedirect(offsiteUrlString);
...
}
L
The redirect exception doesn't seem to have made it from Tap4 to T5.
What is the magical incantation??
Thx.

Re: T5 create a grid with columns dynamics?
There is no requirement that there be a class. You can just create your own
implementation of BeanModel and do whatever you choose. BeanModel is an
interface.

Re: T5 create a grid with columns dynamics?
Use the 'model' attribute of the grid to specify a model for the rows. Then in
your backing Java class create the model - e.g., on the pageLoaded() event, or
onActivate() or wherever. E.g.,
@Retain
private BeanModel _model;
void pageLoaded() {
_model = _beanModelSource.create( YOUR_JAVA_CLASS.class, true,
_resources);
_model.remove(" NAME_OF_PROPERTY_TO_REMOVE ");
_model.remove(" NAME_OF_PROPERTY_TO_ADD");
// Add an "Actions" property / column that does not pull data from the
bean
_model.add("actions", null);
}
public BeanModel getModel() {
return _model;
}
You can also create your own BeanModel implementation that stores property
names however you choose and does with them whatever you want...

Re: T5: Tapestry-Hibernate, do we have to save()?
I imagine that if you use Spring's declarative transactions on the service layer so that the read()/get() method does not start a read/write transaction but the save() method does then changing the object without calling "save()" should just work - you won't be in a read/write tx and so the changes to the object won't be persisted. I haven't tested this. lasitha <[EMAIL PROTECTED]> wrote: On Nov 19, 2007 10:35 PM, Thiago H de Paula Figueiredo wrote: > I havent't noticed this problem before. Until now, HiberTapestry opens a > transaction when a service method annotated with @Transactional is invoked > and commits it when the method finishes without exceptions. Otherwise, the > transaction is aborted. Let me describe the problem in a little more detail. Assuming a typical OSIV setup, consider the following sequence of events: 1. A form is submitted. 2. The entity that backs the form is retrieved from the db in onActivate() or onPrepare(). 3. The first set of validations pass and the entity's fields are populated by tapestry. 4. Our onValidate() method finds some problem and records errors on the validation tracker. 5. Tapestry redirects back to the same page so the user can correct their inputs. 6. The request ends and the active session is flushed. In the above sequence, we don't want to commit the modifications to our entity, but the automatic dirty check initiated when the session is flushed will detect and commit the changes from step 3. Note that the method to save our changes (that is presumably @Transactional) is not even reached in this scenario because we never hit onSuccess(). Does that make sense? Max, Jonathan and Ognen seem to confirm that this is indeed a real consideration. I suspect the solution is as simple as setting the hibernate flush mode to MANUAL (and switching it AUTO just for the duration of an explicitly declared transaction) - the way the spring folks do it. Cheers, lasitha. P.S. I goofed up the link to the spring OSIV interceptor in my previous post.

Re: T5 Newbie : populate the value of a form in a bean

If so, see the BeanEditForm's implementation of void onPrepareFromForm()

here it is, I remove the "offending input"

I think the problem does not come from tapestry but from me.
I want to populate from the form directly to the bean. But this require
to use either the beanEditForm or a custom component.
I 'm just influenced by other framework like struts2 for instance :
If you have something like that in your form
[input]
When the form is submitted struts2 tries to find if the controller
features a user property, and then if user features a name property
If the answer is yes to both it calls controller.getUser().setName("bla");

Re: T5.0.6 - GirdModelProvider for GridRows - example?
Maybe you've got a different Model class. The add() method with a null conduit
works fine.
That said, I didn't realize you were inside a form. Howard as mentioned that
this is an area that needs work.

I am looking for a grid inside a form. A grid row (GridRow component?)

a textfield and a checkbox for example.

Re: T5.06 Project tree
The main requirement for folder structure is based on on Tapestry but on the
servlet specification. Web accessible files in a .war cannot but in the
WEB-INF folder. Tapestry lets you put .tml files either in the the regular
place for web accessible files or in the WEB-INF at the same location
(folder/package) as the corresponding .class file.
How one chooses to layout a folder during dev is, for my money, 100% up to the
developer. That said, there are certain layouts that work very well with
certain tools. For example, I use Eclipse. I start with a "Dynamic Web
Project" type, stick all the .tml files in the WebRoot folder, all the .java
files in the src folder and everything works fine and I can launch the app
without packaging a .war file. I can launch it via either Tomcat or Jetty too.

When I see the Snapshot for the typicall project, there is something else as
Project tree, and I don't want to follow the architecture. Having the

A web application is not defined like that usually, why to change the way?

Re: TextStreamResponse and XML and UTF-8
This is another way to do it. Look at the code for TextStreamResponse. Write
your own StreamResponse impl that's backed by a ByteArrayInputStream.
(The reason I avoid that approach is (a) you create an InputStream to write a
response, so under the covers Tap5 is reading from it and writing to the actual
HTTP output stream which means that (b) the performance is a bit degraded and
(c) you have to hold the whole reply in memory rather than streaming it back to
the client.)
Fernando Padilla <[EMAIL PROTECTED]> wrote: Essentially, you gave it a string
(UTF16 in memory), and it is being
converted into bytes ( string.getBytes() within TextStreamResponse ).
And the contentType of the response is set also from TextStreamResponse.
I would double check what the string.getBytes() is returning, maybe it's
actually putting out bytes in UTF-8, but the HTTP response assumes it's
not in UTF-8, but ISO-LATIN-1 or somesuch. So you're getting the
correct bytes, but they are being interpreted wrong..
1) you might just have to add the charset to the mimetype..
"text/xml;charset=UTF-8"?
2) If you want your 3rd party library to take over more rendering, then
create StreamResponse object that goes from a byte[] instead of a
String, then you have full control on how that strings gets encoded
(utf-8 charset).
3) Maybe there is a bug/enhancement here and
StreamResponseResultProcessor, and TextStreamResponse should be paying
more attention to the charset of the mimetype.

Re: TextStreamResponse and XML and UTF-8
You can override one of the page render methods (I think onactivate is one of
those, but check the Tap5 website) and return false to tell Tap to skip
the other steps of page rendering.

Inside onActivate I obtain a PrintWriter from the injected Response, using
"application/xml; charset=UTF-8"
as content type. I print a small test xml string in printwriter and then I
flush the printwriter.
I return null in onActivate().
Did I do something wrong?

Re: TextStreamResponse and XML and UTF-8
If you're just returning an RSS feed you probably don't want any page wrapping,
etc. In that case you can:
@Inject
private Response _response;
You can then do things like setting headers and even write directly to the
container-provided OutputStream - bypassing the whole TextStreamResponse --
just have your method flsuh() the output stream and return null. This should
also give slightly better performance.

The same feed is displayed fine when I requested through a simple servlet.
I can see the characters in the returned string, and if I save the page
source as an UTF-8 file I can displayed it correctly.
However, I can't make my browser or my GUI to display the xml if I directly

Re: T5.0.6 - GirdModelProvider for GridRows - example?
Maybe you could show more of your .tml (and .java) file(s). I'm new to Tap5
and all I've discovered so far in the realm of models is how to supply a one to
a BeanEditor and to a Grid. I've never gone to the level of t:gridcell and
from what I've learned one generally does not need to -- you can configure a
lot at the t:grid level and via nested t:parameter elements.

Re: T5.0.6 - GirdModelProvider for GridRows - example?
It's a two step process.
1. Define a model in your Java class. It's easy to just use the standard
definition and extend it like so:
@Inject
private BeanModelSource _beanModelSource;
@Inject
private ComponentResources _resources;
@Retain
private BeanModel _model;
void pageLoaded() {
_model = _beanModelSource.create(VideoClip.class, true, _resources);
_model.remove("id");
_model.add("action", null);
}
public BeanModel getModel() {
return _model;
}
Note the _model.add("action", null); that sets a null conduit meaning the grid
will not try to pull values for that column from the underlying bean. In other
words, its a utility column where you can put whatever you like. Note the name
of the model is just model as its accessed via the getModel() method.
2. Add a model="name-of-your-model-in-your-Java-class" to your grid in your
.tml file. In this case it is model="model" e.g.:
${video.title}
Edit
I've added a bunch of other stuff, but you should get the idea.

Re: T5: CreatePageLink and list of context
Take a look at the pageLink component and its "context" parameter along with
activate/passivate methods on the target page.

this does not work, it has something like this:

what's the correct way? Thanks.

T5 adding custom parameters to a BeanEditor
I'm wanting to add custom t:parameter elements to a beaneditor within a Form. This is not a BeanEditorForm, but a vanilla Form element with a beaneditor within it. Screencast #5 shows how to add custom t:parameter blocks to a BeanEditorForm. I've tried similar with a BeanEditor - adding the blocks both within the BeanEditor element and outside that element but within the enclosing element. No luck either way. I'm very new to Tap5. Any pointers? Thanks, Ezra E
