T5 PageRedirectExeption
What is the equivalent to throwing a PageRedirectException in T3, T4 in T5? I have a page that has some context activation handler that does validation of the page context parameters, and if not valid, redirects to a different page. I did this in previous versions of Tapestry using the PageRedirectException class, but not sure what to use in T5.

T5 Page Engine
Greetings,
I'm trying to create an engine in tapestry which is capable of determining
which page to display and can also provide parameters. I currently have a
tapestry 3 application which does this via the old
tapestry.engine.AbstractService.
What I've come across so far is using a Dispatcher which is contributed
before the PageRenderDispatcher that resolves the page name to be displayed
with the parameter values needed. My web pages will contain links (\a
href...) that points to a given url which matches the Dispatchers name. Of
course, the dispatcher checks the page name and if matches processes and
determines the page name, otherwise normal dispatching occurs.
My problem is when the dispatcher is dispatching a request, how can I
redirect to a page and inject objects needed by the page?
My page html:
\a href=/mywebapp/mydispatcher?someparameter='somevalue'My Link\/a
Java - Tapestry Dispatcher
Public class MyDispatcher implements Dispatcher
nbsp;private ComponentSource componentSource;
nbsp;Public MyDispatcher(ComponentSource componentSource) {
nbsp;nbsp;this.componentSource = componentSource;
nbsp;}
nbsp;@Override
nbsp;public boolean dispatch(Request request, Response response) throws
IOException {
nbsp;nbsp;String path = request.getPath();
nbsp;nbsp;if (mydispatcher == path) {
nbsp;nbsp;nbsp;nbsp;String pageName =
functionThatWillGetPageNameFromRequestParameters(request, response);
nbsp;nbsp;nbsp;nbsp;Component page =
componentSource.getPage(pageName);
nbsp;nbsp;nbsp;nbsp;/** Want to inject objects/parameters
nbsp;nbsp;nbsp;nbsp;*** And render/display this page
component [cycle.activate(page) in T3]
nbsp;nbsp;}
nbsp;nbsp;return true;
nbsp;}
}
I'm not sure if this is the correct approach and am trying to port some T3
applications over to T5.
Any ideas or thoughts on how to convert a T3 AbstractService would be
useful.
Cheers,
Marcel

[T5] MVC Issues
I'm having some issues porting some old T3 applications and am stumped with the Ajax implementation. For the most part I've got the basics working, but I'm having problem with some MVC dynamics. Is it possible to create a link at runtime via ComponentResources and specify a zone for the action so that the form is not posted when the action is invoked? Example .tml: lt;t:block t:id=selectionListgt; lt;t:mycomponent t:model=modelA ...gt;lt;/t:mycomponentgt; lt;/t:blockgt; lt;form t:id=filterInputs t:zone=searchZonegt; ... lt;t:actionlink t:id=executeSearch t:zone=searchZonegt;searchlt;/t:actionlinkgt; lt;/formgt; lt;t:zone t:id=searchZonegt; lt;t:delegate to=prop:selectionListgt;lt;/t:delegategt; lt;/t:zonegt; The MyComponent is a component where the model (an actual parameter) may provide a link using the componentResources.createEventLink() method to the component to be rendered. Of course the java class exposes the SelectionList block. As you can see I do have an actionlink in the template which, because of the zone parameter, does not submit the form when the action is invoked. The model is a regular POJO and is not a component, but is part of the Render phase. I'm still trying to get my head around conversion of old T3 applications, so I'm open to new design approaches in terms of how T5 handles MVC.

[t5] actionlink callback
Greetings, Is it possible to provide an ActionLink component with a callback which is invoked after the action event is completed? I have an ActionLink which is used to initiate an AJAX call using a Zone. I'd like to be able to call a JavaScript function on click as well as once the action event is completed. I am able to call a function using the onclick of the inner component of the actionlink ex: t:actionlink t:id=myFunction t:zone=myZone ... /t:actionlink I've been able to use the OnEvent mixin on TextField to use the onCompleteCallback property to call a post JavaScript. However, when doing so on an ActionLink, nothing happens. ex. t:actionlink t:id=myFunction t:zone=myZone t:mixins=t5components/OnEvent event=action onCompleteCallback=afterFunction .../t:actionlink Can this be done in the Java class event handler for the event? I've tried different techniques, but nothing seems to work. Any ideas how to provide event callbacks in T5 (5.0.16)?

[T5] actionlink context
Greetings,
I have a form that contains a single input text box and an actionlink
component. The action link is an event handled by a method in the
implementing java class. What I'd like to be able to do is in the event
handler, be able to access the value entered in the input field. This is
pretty much a search function, where the event handler executes a search
based on the input value. This is being done in AJAX so the search needs to
execute without a full page refresh.
.tml
input type=text value= id=criteria/
t:actionlink t:id=searchExecute context= /
.java
@OnEvent(value=searchExecute)
void searchExecute() {
// need something like
Stirng value = getValue(critieria)
...
}
Is there anyway to access the value for the criteria input field in the
searchExecute method? I tried looking at the
Request.getParameter(criteria), but that returned null.
Thanks,
Marcel Sammut

Re: [T5] actionlink context
Thanks, I've heard of this in 5.0.16 but not sure how to use it. In my
actual implementation, I am creating the link via
ComponentResources.createEventLink. Can I still use that method to create
the LinkSubmit?
Also, looking at LinkSubmit API, it states that this link will submit the
form. Will this not trigger a page refresh though? If the input field is
within the form, how do I obtain the value on the event handler? Will all
the form field's be posted to the method? I don't understand how using the
LinkSubmit differs from EventLink in this case?
Thanks,
Marcel

I suggest you to use a Form and and a LinkSubmit (new in 5.0.16) instead
of an ActionLink to do that.

Re: [T5] Persistent fields may not be updated until after the page has finished loading
I had the same problem when moving to 5.0.16. It was pretty simple for me, since what I was doing was initializing my persistant variables in the declaration.

[T5] Delegate Rendering
Greetings,
Is it possible to use the Delegate component such that the delegation of the
rendering be given to a method in the page, or to a rendering class instead
of a Block or Component? In the example below, can the onDelegatemethod be
used to render the contents (ie. return a stream or use the MarkupWriter) of
the delegate?
The old T3 Delegate component was used this way, but I'm not sure how to do
the same in T5. I have my own IRender interface (similar to T3) that is
returned to the delegate component. For Example:
MyPage.tml
t:delegate to:onDelegate /t:delegate
MyPage.java
public void onDelegate(MarkupWriter writer) {
writer.element(table);
...
}
Any thoughts or suggestions?
Thanks,
Marcel

Re: [T5] Ajax And Zones
So am I dead in the water here? Sounds like this functionality isn't supported in T5? Seems strange that Tapestry 5 requires an INPUT field to be contained within a Form, and AJAX uses Zones, and you can not combine the two. So basically, AJAX functionality in T5 should only be used with straight text and HTML, no input fields. In my situation, the AJAX component doesn't contain a Form, but the components container may, so how do you use AJAX Zones with forms...for example, dynamic content.

[T5] Ajax And Zones
Greetings,
I have a component which displays a header and body contents, where the
contents are collapsed via AJAX support. The component is a DIV which wraps
a table that contains the header, AJAX block and Zone. There is an
ActionLink which is used to invoke the AJAX method that returns the AJAX
block to be rendered in the Zone via a delegate component. The basic AJAX
concept was derived from the following example:
http://202.177.217.122:8080/jumpstart/examples/javascript/ajax
Everything is ok and the contents are not rendered when the AJAX ActionLink
is invoked. That is done by returning null from the event handler. The
problem occurs when the event handler returns the AJAX block to be rendered
again (i.e.: expand the contents). Note, that the component itself is
wrapped within a form on the page. I recieve the following error after the
AJAX method exists and returns a valid Block component:
No object of type org.apache.tapestry5.services.FormSupport is available
from the Environment. Available types are
org.apache.tapestry5.RenderSupport,
org.apache.tapestry5.ValidationDecorator,
org.apache.tapestry5.internal.services.ClientBehaviorSupport,
org.apache.tapestry5.services.Heartbeat.
Here is my template:
div xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd;
table
tr
td t:actionlink t:id=updateState
t:zone=ajaxZoneId ${stateImage}

Re: [T5] Creating Links At Runtime
I'm aware of the large gap between 3 and 5 and may require some redesign on
my part. That is why I'm using native tapestry links. In 5.0.15, the
ComponentResources class has the createActionLink deprecated in favor of
createEventLink. There are only 2 difference between ActionLink and
EventLink according to the API, the way it is controlled and the way it is
triggered.
I do want to use an EventLink in my situation, and do this through
ComponentResources.createEventLink(). The tutorials show you how to use the
ActionLink in a template, whereas in my case, the component is created via
Java code. Perhaps I do not understand what the context argument in the
createEventLink() method is used for. I believe that the first argument
would be the name of the method to invoke? How do you identify the handler
of the event when creating the EventLink? Tutorials show this binding done
through the @OnEvent annotation and specifying the event name via the
component attribute in the annotation or the id attribute of the
element.
How would I bind these properties using a pure Java implementation? My
previous T3 components never had a template file, and rendered purly in
Java.

I seem to be able to render the anchor component based on the Link being

As a follow-up:

This is not quite correct.
The component attribute of the @OnEvent annotation identifies which
/component/ generates the event, but not which event is generated.
It's the value attribute that specifies which event to listen to:
.tml:
t:eventlink t:id=mycomp event=myeventClick Me/t:eventlink
.java:
@OnEvent(value=myevent,component=mycomp)
void someHandler() {
}
This will not be called because EventLink triggers the provided event not
on
itself, but on its container. Omit the component attribute for this to
work
as written.
Or, if you prefer convention-over-configuration:
.java:
void onMyeventFromMycomp() {
...
}
Or even:
void onMyevent() {
...
}
This will work because it intercepts the event notification fired on the
page (the container of the EventLink instance).
I've been asked which to use: EventLink or ActionLink. I think, possibly,
if I had created EventLink first, I would not have created ActionLink.
That being said, ActionLink is useful when you have many one-off
components
with individual logic on each ... it's easier since you specify (in the
template) a unique component id, which you would do anyway. You just have
to match that id against an event handler method name.
EventLink is when you have multiple components in the template that should
trigger the same behavior. You can usually omit the component id, but you
have to carefully coordinate the event name in the template and in the
Java
class (either inside the @OnEvent annotation, or
as part of the event handler method name).

Hi Marcel,
The binding of the listener to the event is done automatically by
tapestry
based either on the @OnEvent annotation or by naming convention.
The context argument is simply used to allow for additional information
to
be encoded into the url which will be provided to the handler in the
form of
method parameters.
For example:
.html:
${myLink} My Link
.java:
@Inject
private ComponentResources resources;
public Link getMyLink() {
return resources.createEventLink(myevent,value1);
}
@Inject
private ComponentSource componentSource;
Object onMyevent(String name) {
//do something interesting. Here, we look up a page based on the page
name provided in name.
return componentSource.getPage(name);
}
And that's it. Now when you click MyLink, the onMyevent method will
be called, passing in value1 as the value of the name parameter.
* The values in context will be converted to and from strings via the
ValueEncoder service contributions.
* Events always bubble in T5, so your handler has to be either at the
level of the component which has the link, or in a class that wraps that
component. That is, suppose the following page structure:
page x
- component a
- event link, event is foo.
- event link, event is bar.
The handler for the foo event must be in either component a or in page
x. The handler for bar must be in page x. A handler for the bar
event
in component a won't be called by clicking the event link of page x.

This sounds straight forward, however, I am unable to determin how to instantiate, for example, a new instance of a ActionLink. In the previous version (3.0), I simply rendered the anchor myself and generated the URi in a custom implementation. I was hoping that in T5, I would be able to use the internal Link components since they do pretty much what I was doing in 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. - Marcel -- View this message in context: http://www.nabble.com/-T5--Creating-Links-At-Runtime-tp20274715p20274715.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]
Re: [T5] Creating Links At Runtime
Thanks for the quick response. My delima is that I need to have a reference
to the link in the .tml template. I was hoping to just use a pure Java
implementation to let the developer configure the menu via code.
In order to do this, I believe I have to inject the ComponentResources
object of my container when instantiating the AbstractLink component. Any
idea to do that?
Thanks,
Marcel

Why not just use ComponentResources.createActionLink and
ComponentResources.createPageLink?
.tml:
$somelink Link Text
.java:
@Inject
private ComponentResources resources;
public String getSomeLink() {
return
resources.createPageLink(mypage,true,contextValue1,contextValue2,...);
}

[T5] Customizing BeanEditForm Layout
I've been able to extend and customize the layout and order of a BeF using
the parameter element. However, when I try and customize the Submit
button, the parameter element doesn't seem to work. I've read/seen that
you can specify the label of the button via the submitlabel parameter of the
BeF, but I need to do more than just the label.
For example, how would I add an ActionLink component right beside the submit
button? Below is my template for the beaneditform (v5.0.15):
t:beaneditform t:id=loginForm t:object=loginForm
submitlabel=message:submit
t:parameter name=password
label t:type=Label for=password style=width:110px;/label
input t:type=PasswordField t:id=password
t:value=loginForm.password/input
/t:parameter
t:parameter name=submit
label t:type=Label for=submit style=display:none;/label
input t:type=Submit value=message:submit /input
t:actionlink t:id=switchDisplay ${message:label-change}
Link/t:actionlink
/t:parameter
/t:beaneditform
Thanks,
Marcel S.
