Form submission in Tap5
Hi, I am trying to build a simple GET based form to implement a search box. All the examples (that I could find) seem to focus on forms using POST to create new entities. Is there an example to show simple GET based form requests? Thanks, Vinayak - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Accessing ApplicationStateManager from within a Filter
You have to make your Filter a Tapestry service in your module and you have to have a constructor parameter which is of type ApplicationStateManager. No need of @Inject inside your Filter.

Re: Form submission in Tap5
Tapestry restricts the Form component, and form submissions, to using POST.

Re: Accessing ApplicationStateManager from within a Filter
When you contribute a filter, you need to instantiate it. Generally
it looks something like:
public void contributeRequestHandler(OrderedConfigurationRequestFilter
configuration, ObjectLocator locator)
{
configuration.add(MyFilter, locator.autobuild(MyFilter.class));
}
The ObjectLocator is a resource of the RequestHandler service that can
be injected into contribute methods for the RequestHandler service and
allows access to other services within the IoC Registry; it also
handle instantiation of objects with injection for you. So MyFilter
doesn't have to be a service but can still be injected. Contributing
an object instance to a filter does not do any injection, but
autobuild() does.
In the current .16 snapshot, you can use @Inject on fields of MyFilter
in addition to injection through the constructor. This was added
because people got confused: in pages and components you use @Inject
on fields, but in service implementation, 5.0.15 requires that
dependencies be passed through the constructor. Again, 5.0.16 allows
you to code services and other objects more consistently (but with the
runtime overhead of using reflection to update the private fields).

Re: [T5] Creating Links At Runtime
a href=${createURL}click me/a
You just have to provide getCreateURL() as a wrapper around
ComponentResources.createActionLink().
You don't instantiate a component, just @Inject the ComponentResources.

idea to do that?

3.0.
Is there a way, in code, to create a new ActionLink component and
have it
act as the model for another component to be rendered?
Your thoughts are much appreciated.

Re: [Tapestry 5.0.15] - Hidding client-side validation
This can be done by monkey patching the Tapestry JavaScript. You can have a JS library that overwrites the definitions of some of the built-in Tapestry functions related to validation. In this way, you can prevent the pop up bubbles, or change how the validation messages are presented to the user.

Re: [T5] Creating Links At Runtime
Thanks!
I seem to be able to render the anchor component based on the Link being
created from the ComponentResources.createActionLink(). However, the action
does not seem to be fired when I hook up the event using the @OnEvent
annotation. The anchor is rendered using the MarkupWriter.element() method
using the Link object to define the href attribute.
Note, that the creating and rendering of the action anchor is done purely in
Java...no template.
My anchor renders the following url:
mypage.pagelayout/activate Activate
There is a page called Home/MyPage and on this page is a component called
PageLayout which is an extension of my Layout component. In the PageLayout
component, I have my activate event handler as follows:
@OnEvent(component=activate)
public Object activate() {
...
}
Any idea why the activate event is not being called and how I can hook the
event to the action?
Thanks Once Again.

Combine a form and response in same template/Java class
I currently have a very simple webapp. I have a form and return a pageable grid component based on the form parameters. Right now, I have the form and response as separate tml/Java classes. Everything works fine, but it's getting to be a pain to keep all of these pieces in order (2 templates and 2 Java classes per query x 10 queries). I'd like to combine the form with response so I only have to maintain one tml and one Java class per query. What is the logic I need in my class/template to do this? So far, my attempts have been unsuccessful. I tried to add a Persist boolean and set it to true in the onSuccess method and included an if-else in the template to render the appropriate piece. If I just used @Persist, I couldn't get back to the form to ever load again once it was submitted the first time. If I used @Persist(flash), I could reload the form on demand, but now the grid pager links would take me back to the form (since the boolean would reset to false). Does anyone else combine their forms and response pages? Is this a bad practice? It just seems silly to have to keep track of 4 entities for a simple form/response. Boy do I miss Perl. -- View this message in context: http://www.nabble.com/Combine-a-form-and-response-in-same-template-Java-class-tp20287170p20287170.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
