Re: How to let custom component participate in form submission

[Chris Poulsen]

Hi

It sounds like you are attempting to do something in a way that may not be
ideal (judging from all the hoops you are trying to jump through).

In Tapestry you can usually get really far using the simple building blocks
that are provided. With a few exceptions you are usually taking a bad
course, when you think you need to write all kinds of weird code to make
the framework happy (Exceptions are usually things like when the (complex)
built-in components like grid and tree does not support what you need).

You seem to have a somewhat unclear understanding of component rendering
and form submissions, that could be a place to start. (Hint. take a look at
the Form component
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/corelib/components/Form.html
- That is the one that triggers those prepare* events etc, there is no
magic going on in pages with respect to that. As events bubble "up" through
containers, you should not expect your component to receive those events if
it is _inside_ the form. If you want something complex acting like a form
element, use Thiagos suggestion).

I would recommend against trying to implement some kind of pub/sub
mechanism to circumvent the fact that you feel your components are
misbehaving because events bubble up... - It may be possible to get
something to work, but with respect to maintenance and component
re-usability you will most likely end up realizing that you have shoot
yourself in the foot, at some point.

With a few exceptions, I would generally say that using @Persist in
components is a smell, instead pass the information as a parameter - Pages
are ultimately the things driving the components, they should worry about
how to configure the components (if that means that a value should be
persisted, it should happen in the page).

Also if you find yourself needing page life-cycle callbacks in your
component (e.g my component should do this on activate or similar, you are
doing it wrong)

It is hard to come up with something concrete based on the info provided,
but I guess that if you realize how form submission and component render
life cycles interact, it will be easier to fix your problem.

Re: How to let custom component participate in form submission

[abangkis]

Hi Thiago,

This component is some ui that we extract from few common pages. It shows a
series of tabs. Each tabs has its own related Hibernate Entity. We don't
pass all the tabs entity as parameter to the component. Instead we just
pass the root component and let the rest of the tab get their entity from
the DAO injected to the component.

The component is encapsulated inside of a form. It works well showing the
data for each tab. But when we submit the form we receive that error. Since
the tabs Hibernate Entity is not Persist in the component. Our approach is
to use @Persist only when we have to. Usually this is handled in the page
by populating the tabs Hibernate Entities in the page OnPrepare method.
Translating this approach from a page implementation to the custom
component isn't as straight forward as I thought. Since OnPrepare isn't
called in the custom component. (it's part of page life cycle but not part
of component rendering lifecycle?)

Tried to implement it using Process Submission example from jumpstart
(since it seems that's how you implement a component that contribute the
value to form submission process). But still haven't got it working yet.

By the way. Is it common to have @Persist property inside of a component?
How do you clean the persisted field after submission? Is it enough only by
calling ComponentResources.discardPersistentField() on the page OnSucces
method? Or do we need to clean it up on the Component Java code instead?

Sorry if the explanation a bit long and confusing. Thanks.

Re: How to let custom component participate in form submission

[Thiago H. de Paula Figueiredo]

Hello!

What exactly is this component trying to do? I couldn't get it by looking
at your code snippet.

Anyway, the probably best way of doing it if you want to create a component
which edits something is to subclass AbstractField.

The error message says you're trying to pass a null object to BeanDisplay
while it renders, so this doesn't seem to be a problem with form submission
at all, but a problem while rendering the page later.

Failure reading parameter 'source' of component
common/loan/ApplicationSummary:loanbundleedittabs2.beandisplay_0.loop:
Parameter 'object' of component

How to let custom component participate in form submission

[abangkis]

Hai guys, still working on my custom component.

How do we let our custom component participate in form submission.
Apparently there is no onPrepare hook for tapestry custom component.
http://tapestry.apache.org/component-rendering.html.

I'm reading
http://jumpstart.doublenegative.com.au/jumpstart/examples/component/subformvalidation1
example. But still haven't grasp the general gist
about ProcessSubmission/ComponentAction. Calling the prepare method from
process submission doesn't seems to work. Rendering the component is fine,
but when submitting the page I receive the error and stack trace bellow.

Any advice? Thanks.

Here's my custom component setup & prepare method:

private static final ProcessSubmission PROCESS_SUBMISSION = new
ProcessSubmission();

// Tapestry calls afterRender() AFTER it renders any components I
contain (ie. Loop).
final void afterRender() {

// If we are inside a form, ask FormSupport to store
PROCESS_SUBMISSION in its list of actions to do on submit.
// If I contain other components, their actions will already be in
the list, before PROCESS_SUBMISSION. That is
// because this method, afterRender(), is late in the sequence.
This guarantees PROCESS_SUBMISSION will be
// executed on submit AFTER the components I contain are processed
(which includes their validation).

if (formSupport != null) {
formSupport.store(this, PROCESS_SUBMISSION);
}
}

private static class ProcessSubmission implements
ComponentAction {
private static final long serialVersionUID = -2132279249191788845L;

@Override
public String toString() {
return this.getClass().getSimpleName() + ".ProcessSubmission";
}

@Override
public void execute(LoanBundleEditTabs2 component) {
component.processSubmission();
}
}

private void processSubmission() {
// Validate. We ensured in afterRender() that the components I
contain have already been validated.
prepare();
}

@SetupRender
void setup() {
prepare();
}

void prepare() {
Long loanApplicationId = loanApplication.getId();
loanApplicationDetail =
loanApplicationDetailDao.getByApplicationId(loanApplicationId);

homeAddress =
loanAddressDao.getHomeAddressByApplicationId(loanApplicationId);
homeAddress2 = new AddressModel();
addressCopier.copy(homeAddress, homeAddress2);

mailAddress =
loanAddressDao.getMailAddressByApplicationId(loanApplicationId);
mailAddress2 = new AddressModel();
addressCopier.copy(mailAddress, mailAddress2);

officeAddress =
loanAddressDao.getOfficeAddressByApplicationId(loanApplicationId);
officeAddress2 = new AddressModel();
addressCopier.copy(officeAddress, officeAddress2);
}

Here's the stack trace

Re: Get link to the page that contains custom component

[abangkis]

Apparently environmental only available during rendering.

https://www.mail-archive.com/users@tapestry.apache.org/msg56293.html

Yeah. I guess I still doesn't understand how to use Environmental
Correctly. Would try passing it as a parameter instead.

Thanks.

Re: Get link to the page that contains custom component

[Mats Andersson]

What do you think about passing the model as a component argument 
instead? That way you are not depending on the order of the calls. See 
also: 
http://jumpstart.doublenegative.com.au/jumpstart6/examples/navigation/whatiscalledandwhen 
for an explanation.

What did I do wrong?

There's another thing. If the custom component inside a form and like to

If it's a page we can do something like:

@InjectComponent
private Form form;

form.recordError(message);

How to do something like that in a component?

Thanks a lot.

Re: Get link to the page that contains custom component

[abangkis]

Sorry, still having some problems with custom component. I need to pass a
logged in user object to the component.

So I push the wrapper class from the page to the environment

@BeginRender
void beginRender() {
  LoanBundleModel model = new LoanBundleModel();
  model.setUserId(getCurrentUser().getId());
  environment.push(LoanBundleModel.class, model);
}
And then retrieve it in the component by using environmental

@Environmental
private LoanBundleModel model;

And use it in a method like this:
@CommitAfter
@OnEvent("DeleteDoc")
void deleteDoc(Long loanDocumentId) {
  User user = userManager.get(model.getUserId());
  String message =
loanDocumentService.deleteLoanApplicationDoc(loanDocumentId, user);
if (message != null) {
  validationTracker.recordError(message);
}
}

But i keep getting. No object of type
net.mreunionlabs.gri.server.compmodel.gri.LoanBundleModel is available from
the Environment.

What did I do wrong?

Thanks

Re: Get link to the page that contains custom component

[Dmitry Gusev]

For forms you can use:

@Environmental
private ValidationTracker validationTracker;

and then

validationTracker.recordError(...)

Re: Get link to the page that contains custom component

[abangkis]

Thanks a lot Dmitry. It's working great.

There's another thing. If the custom component inside a form and like to
set some error message.
If it's a page we can do something like:

@InjectComponent
private Form form;

form.recordError(message);

How to do something like that in a component?

Thanks a lot.

Re: Get link to the page that contains custom component

[Mats Andersson]

Hi,

I think you should use ComponentResources to create an event link to 
your new component. The link will include the current page.


Another solution is the getPageName method of ComponentResources.

Hi,

I would try something like this:

Custom component not rendering

[Matthew Bush]

Hello.

Problem - Custom component rendering multiple text fields is not rendering and 
no error produced.

I am wishing to create a custom tapestry component which uses a *.tml template. 
 This custom component is to provide data entry for Address entities.  So 
includes normal/typcial address fields.  I have tried to use various *.tml 
syntax such as:

http://tapestry.apache.org/schema/tapestry_5_4.xsd”>
http://tapestry.apache.org/schema/tapestry_5_4.xsd”> 
with either http://tapestry.apache.org/schema/tapestry_5_4.xsd”>

My package structure/location is -

java package au.com.xxx.web.components.technology.common
tmp under resources at au.com.xxx.web.components.technology.common

And the page where I use this component references the component like this -

tml template - 
java - 

 @InjectComponent("billingAddressEntry")
private AddressEntry billingAddressEntry;

If needed I can attach source for both the custom component and usage page.  

Can custom components handle rendering multiple fields and do this using the 
*.tml rather than manually doing layout using beginRender method?

Matt Bush

You might be able to use the onEvent mixin to attach a clientside event to
a serverside event.

Easy!

Now pass eventLink.toClientURL(); to your JavaScript code through some  
JavaScriptSupport method. Use this URL as the target of an AJAX request.  
Pass any data you want as query parameters.

Re: guidance with integrating yet another js library as custom component

[George Ludwig]

I've got this working pretty well now, but I want to take it to the next
level.

When the user clicks on a node of the graph, I want to trigger a callback
function on the java side. I assume this means attaching a click handler
method in javascript to the nodes...but how do I wire it up so when the js
click handler is invoked, it calls a server side java method?

Looking at this example: http://sigmajs.org/examples/hidden_nodes.html

When a node is clicked, I'd like to execute a server side java call that
receives the node name.

Is there a clear example of this type of integration anywhere I can take a
look at?

-George

Re: guidance with integrating yet another js library as custom component

[George Ludwig]

Lance,

I've been using, for example:

@Inject @Path("context:/data/filename.gexf")
@Property
private Asset file;

And then I pass this to the JS function:

String ret= file.getResource().getPath();

It's working fine...but is toClientURL() the preferred method?

Are you sure the files is really available at that URL? I don't think  
so.When Tapestry doesn't find a file matching a request, it treats it as a  
page request (render or event). As you probably don't have a page named  
'myfile', Tapestry thinks you're doing an event request to the Index page.


Make sure you have a correct, valid URL to the file before going ahead.

I think you want to @Inject the AssetSource to lookup the Asset. You can
then call Asset.toClientUrl() to get an href for the asset which you can
pass to your js library to use.

Re: guidance with integrating yet another js library as custom component

[George Ludwig]

Here's my final (I hope block):

What is happening is that when I try to load anyfile.anyextension using
javascript, the tapestry app always returns the contents of index page,
rather than the contents of the requested file.

I also tried loading the file straight from the browser (i.e.,
http://localhost:8080/myfile.ext) and it still returns the contents of the
index page. It returns the same thing even when I type in a URL for a
non-existent file.

Is this a tapestry or jetty setting that I've missed?

Re: guidance with integrating yet another js library as custom component

[George Ludwig]

Thiago,

You're definitely right, it's now a JS issue. I figured out that somehow I
had downloaded a garbled sigma.parseGexf.js file, which was part of the
problem.

Quick javascript question: when I pass the filename for parsing to the gexf
parser, I currently pass it with relationship to the webapp root...but
since it still does not render (and everything else looks good right now),
I'm assuming that I the JS needs a fully qualified local path.

Thanks again for your input...

-George

 For the parameter, it will make no difference. Regardless of using
 addScript() or addInitializerCall() you'll need to pass the file name in
 the parameters of these methods. As you've never did this before, use
 addScript(), which is easier.

Uncaught SyntaxError: Unexpected token < sigma.parseGexf.js:3
Uncaught TypeError: Object # has no method 'parseGexf'  
tap5-sigma.js:24


Are you sure sigma.parseGexf.js is correct? What's in line 24 of  
tap5-sigma.js? Anyway, it seems that now this error is completely about  
Sigma and JavaScript and not about Tapestry itself. What Tapestry version  
are you using? JavaScript minification is enabled?

For the parameter, it will make no difference. Regardless of using

in

the parameters of these methods. As you've never did this before, use
addScript(), which is easier.

Re: guidance with integrating yet another js library as custom component

[George Ludwig]

I'm at a point where it seems to me that it really should be working, yet I
get this error in the javascript console:

Uncaught SyntaxError: Unexpected token < sigma.parseGexf.js:3
Uncaught TypeError: Object # has no method 'parseGexf' tap5-sigma.js:24

The method it can't find, parseGexf, is in the file sigma.parseGexf.js, and
I've included it in the component's java file:

@Import(library={"classpath:com/intuit/tapestry5/sigmajs/asset/sigma.min.js",
 "classpath:com/intuit/tapestry5/sigmajs/asset/sigma.parseGexf.js",
 "classpath:com/intuit/tapestry5/sigmajs/asset/tap5-sigma.js"})


Here is the complete javascript file that is being executed in order to do
the initialization:

var sigmajs = Class.create();
sigmajs.prototype = {
initialize : function(id, gexfFile) {
 // Instantiate sigma.js and customize rendering
var sigInst = sigma.init(document.getElementById(id)).drawingProperties({

});

This seems to be a load order issue, yet I tried swapping the order of

That's the route I ended up taking to import the necessary js files, but
I'm still unclear on exactly how to use  JavaScriptSupport.addScript() to
create an instance of the sigma viewer.


Whatever you pass to addScript() is added inside a  tag  
inside the HTML as is. So, if the function that sets up your code in  
JavaScript is initializeGraphs(), for example, call  
JavaScriptSupport.addScript("initializeGraphs()");. If you need to pass  
some data to it, remember that addScript() follows the String.format()  
format.



For example, I don't understand
when it's appropriate to use JavaScriptSupport.addInitializerCall()
vs. JavaScriptSupport.addScript()


Initializer calls are just another way of doing the same, a better one  
than addScript(), but in a harder way. addScript() takes raw JavaScript  
and adds it to the page. An initializer is a function added to the  
Tapestry.Initializer object. addInitializerCall() takes the name of this  
function and the value of the parameters you'll pass to it.

guidance with integrating yet another js library as custom component

[George Ludwig]

I'm working on a custom component of the SigmaJS visualization library (
http://sigmajs.org).

Specifically, this example: http://sigmajs.org/examples/gexf_example.html

I'm starting with the simplest use case, which is to create a sigma viewer,
passing it a single parameter, which is the name of a GEXF file for it to
parse and display.

I've been studying the got5 examples of js library integration, and they
are all pretty complex, and it's a challenge to figure out what I really
need to do.

I've been working form this tutorial:
http://wiki.apache.org/tapestry/Tapestry5AndJavaScriptExplained however,
it's for a mixin and I'm unclear if there is a material difference between
creating a component vs. a mixin.

Any guidance is much appreciated!

How to access a component(any text field) from custom component

[SAMPY]

Issue is related to Tapestry 4 validation issue.
HTML :





where this PaymentSelection is component, that renders the html dynamically
that consist of code as text field. 

Validation Java Code : 

FormBean bean = this.getHotelsFormBean(); 
IValidationDelegate delegate = this.getValidationDelegate(); 

boolean isValid = super.validateForm(bean, delegate); 

try { 
if(Utils.isNullOrEmpty(bean.getHotelName())) { 
String message = this.getMessages().getMessage("bb_ERR5"); 
this.error(delegate, (IFormComponent)
this.getComponent("hotelName"), message, 
   ValidationConstraint.REQUIRED); 
isValid = false; 
} 


 message =  this.getMessage("valid", new String[] { "cardnum" }); 
 this.error(delegate, (IFormComponent)
this.getComponent("paymentSelectionComponent").getComponent("code"),
message, 
 ValidationConstraint.REQUIRED); 

this.getComponent("paymentSelectionComponent").getComponent("code") : this
says as component out of the particular page. but it doesn't bind the error
to the component.

Re: Custom Component Id Other than Class Name

[Dragan Sahpaski]

I guess it's possible that you put components into different "virtual
folders"/packages and then make different library mapping names for
them.

Custom Component Id Other than Class Name

[Bob Obringer]

I've created a library of custom Tapestry components and have been unable to 
figure out how to use an ID other than class name to reference those 
components. 

The library I'm creating is part of a much larger framework and as such I have 
requirements for class names.  These names are not what I would like to use for 
the component ID and I've searched everywhere for a way to customize the ID.

I assume the answer I'm looking for will be "no it's not possible" or "yes, 
here's a simple solution" but have been unable to find that answer.


Thanks,

Use page message catalog in custom component

[Beat Durrer]

Hi all

I am refactoring some page which have very similar forms.
I thought it would be clever to make a custom component, which
contains a collection of preconfigured form elements.
Some of those fields need page specific field names (the field stay the same).

How can I make page specific messages but still use a component?


- If there is a textfield directly in the page template, I use the
page's message catalog
- If the textfield is put into a component, the page's message catalog
is not applied anymore, only the components catalog.


Cheers.

I think I understood - I was just being stubborn!   Thanks for caring :)
I needed to convert to String, or the ID because of below.

below.
My problem is at render time, everything is fine.
At event time (because it's drag and drop) the context is lost.  Even the 
"value" is lost.
The dragged component has a context, and I retrieve this at event processing.
But I have no idea where the dragged component got dropped - unless I access 
the DOM I guess.
WIth a "context" or something, I can at least iterate through my list until I 
get a match.


I might call it a night - it's just past 11pm here and the coffee will shortly 
wear off :)

It seems to me that you haven't understood what I said: if you pass the  
context parameter without the expansion, your component will receive the  
original object of type Object[], not a String, so you don't need to  
convert a String to an Object[]. In your event handler method, the  
parameter must be an Object[], or, betetr yet, an EventContext.

bugger.  i think it's null anyway...which is probably what you were both 
leading me to.
i had another field in the event method named context anywaywhich was the 
URL of the event in the form of an Object[]

i'm still back at square one - will review what i have done.

thanks

Re: Give Custom Component a "context" that is not Ljava.lang.Object;@828642

[Chris Mylonas]

never never never ... thanks for the tip.  String is fine for me - it's not the 
most efficient way, but I've got a bit of a problem finding out where my 
dragged (and known) component got dropped.

I need to convert from Ljava.lang.Object@234141 to "string representation" or 
what value it is (which happens to be a string) I set during render (so the 
HTML that is output is good enough for me).


Doing it the never never never way - I can (I think safely) get the string 
value, then look it up in my list when the event is triggered (dropped in this 
case).
The dragged object has a parameter that is received, but the droppedOn 
component can only be retrieved with the @OnEvent annotation - which is good 
for a single page full of components -

I have two custom components - 1.  uses draggable, the other uses droppable.  I 
need to know what gets dropped onto what.

It would be like having two grids with one grid full of draggable rows and the 
other grid with droppable rows.
If I can get the string value of the droppable row, I know which object it is 
(my objects have unique string values so I'm safe in that respect).

Never never never ever use expansions when passing parameter values. :)  
Expansions always coerce the value to String and are meant to be used to

Nope.  Tried both context and t:context


HTML came out:

The prop expansion worked ok for html before (below)
Still get [Ljava.lang.Object@34255245 on the event both ways.


I see that using your suggestion is what happens in the Hi-Lo game, when a 
page's template passes a context to the component.
In my case, I'm in the component template - if that makes a difference?


PS - just been reading your OAuth service blogs - hopefully get to 
understanding those things over the weekend - thanks

Give Custom Component a "context" that is not Ljava.lang.Object;@828642

[Chris Mylonas]

Hi List,

I tried giving a custom component a context (just a String) but when I go to 
use it on an event, I get the output to be [Ljava.lang.Object;@783b110a instead 
of "1234" which is what is set during rendering.

The output html looks a little strange compared to the component's tml - like 
I'm missing something:

http://tapestry.apache.org/schema/tapestry_5_3.xsd";>



http://tapestry.apache.org/schema/tapestry_5_3.xsd";>


I'm looking at the PageLink component and it's way of getting a context is as 
an Object[] rather than a simple String.
I'm guessing when it creates the link, there's some magic that happens 
underneath to create the "context" into whatever is used in the template to a 
valid portion of a URL

Link link = resources.createPageLink(page, 
resources.isBound("context"), context);

writeLink(writer, link);

Given my above output "[Ljava.lang.Object;@783b110a" - what's the trick to turn 
this object for t:context="${currentExtension.number}" into context="1234" so 
that the URL that tapestry spits out during the component event look like 
/christest/draggable6.extension.1234.voicemailzone:zonedrop/ISDN1  (where 1234 
is at the moment omitted)

Any hints would be very helpful!!

Cheers
Chris

Yep. Templates are generally easier to read and write, but MarkupWriter is  
better when you have more complex logic and attributes that may or may not

i've spent a few hours today templating my first component with

Each have their strengths.

In this case

e.g.

VM arguments
-Dtapestry.production-mode=false -Dtapestry.compress-whitespace=false

VS

AppModule.contributeApplicationDefaults()
configuration.add("tapestry.production-mode", false);
configuration.add("tapestry.compress-whitespace", false) ;

Which version are you using? What's the value of the configuration symbol  
tapestry.production-mode? Since some not-so-recent version, when not in  
production mode, Tapestry updates the field values so they can be seen in  
the debugger.

First Custom Component -> Confused; source = null, but values populated mysteriously

[Chris Mylonas]

Hello List,

I'm confused.  In setting up the debugger and carefully working through my code 
to watch the "source" and "currentItem" fields, I was always watching them set 
to null.
I've followed through Grid & Loop to find where the values are fetched 
(cachingDataSource for Grid) but there's a lot of null values in debugging as 
I'm used.

When I changed my component's beginRender() on a whim to see if I get an 
exception, I was surprised to see the value that the Grid prints to the screen 
was available to my component - yet everything about it in the debugger says 
null - i.e. source = null, currentItem = null.

Could someone help me understand how to I get my head around this?I think I 
understand that Tapestry wraps all my stuff up in "proxies" via conduits and 
workers and what have you, but it still seems a little odd to see null's in my 
debugger.


Any help will be graciously accepted whilst I try and get some js (jquery) no 
less to work with my component :)

Thanks
Chris

Thanks

My "source" (and whatever the iterator returns) are always null...so I'll have 
to find out why that happens.

Custom Component - @BeforeRenderBody not rendering stuff

[Chris Mylonas]

Hi Tapestry List,

After spending a few hours with render phases and all that comes with it 
(heartbeat/resources) I'm in a bit of a jam that I don't know where to go next.
I'm setting up a basic component called PhoneView that receives an ArrayList of 
Phone objects...similar to the Tree example on the wiki [1]

@CleanupRender & @BeforeRenderBody have the same code to make it easy for the 
beginner (me!) to see his progress...
There are 2 items in the array list I have created using a BeanEditForm, so I 
presume I should see three lots of the div saying "CHRIS! This is your amazing 
test div - " with the render phase name.  (2 x BeforeRenderBody) + (1 x 
CleanupRender).

I'm not :(

Running your eye over this code/template...can you help me?


/**
 * Defines the source of the phones
 */
@Parameter(required = true)
private ArrayList source ;

/**
 * Iterator to go over the source (Phone) elements

private Iterator iterator;

/**

/**

@Parameter

/**

@Parameter(defaultPrefix = BindingConstants.LITERAL)

/**

@SetupRender
boolean SetupRender(){
 if( source == null ){
 return false ;
 }
 this.iterator = source.iterator();
 return (iterator.hasNext());
}

@BeginRender
void beginRender(){
currentPhone = iterator.next();
heartbeat.begin();  
}

@BeforeRenderBody
void beforeRenderBody(MarkupWriter writer){

Element cur = writer.element("div",

"class","userbackground").addClassName("adifferentbackground");
cur.text("CHRIS! This is your amazing test div - 
beforeRenderBody");
writer.end();


resources.renderInformalParameters(writer);
}

}

Create Custom Component + Tapestry 5 API Docs - best place to view?

[Chris Mylonas]

Hi Tapestry List,

I've found a couple of days to create a custom component!
My references are for the task are:

https://code.google.com/p/shams/wiki/Component
https://tapestry.apache.org/component-rendering.html
https://wiki.apache.org/tapestry/Tapestry5HowToCreateYourOwnComponents

Looking for the TAP5 API Docs it says 5.1.0.5
https://tapestry.apache.org/tapestry5/apidocs/

Are there more current ones (5.3.x) available?
Or
How can I bulid my own?  I've checked out trunk and looking at the Grid 
component and want to find out more about the first annotation 
@SupportsInformalParameters

Thanks
Chris

Re: Boolean Return Values in Custom Component Events

[Steve Eynon]

Food for future thought - the way the event return value is used for
multiple purposes and may, or may not be passed to your callback seems
a little messy. Currently we have -

in ComponentPageElementImpl:

  ComponentEventCallback wrapped = new ComponentEventCallback() {
public boolean handleResult(Object result) {
  // Boolean value is not passed to the handler; it will be true
(abort event)
  // or false (continue looking for event handlers).

  if (result instanceof Boolean)
  return (Boolean) result;

  return providedHandler.handleResult(result);
}
  };

I guess I would rather the callback not be wrapped and instead have an
abstract implmentation for the default Boolean behaviour.

Steve.

Boolean Return Values in Custom Component Events

[Steve Eynon]

Hi,

I wish to raise an event from a component and abort further processing
if true is returned from any event handlers - only I don't know how!

ComponentResources.triggerEvent() returns true if *any* event handler
was invoked, regardless of what it returns.

Passing a ComponentEventCallback doesn't work either because (as
quoted from ComponentPageElementImpl source) "Boolean value is not
passed to the handler;"

So it seems Boolean is a 'reserved' event return value. Is there
another way to determine if an event was aborted via a true return
value or do need to make my own Boolean enum?

Cheers,

Steve.

Thanks a lot, that worked. I have injected
ComponentEventResultProcessor("AjaxComponentEventResultProcessor"
implementation)

@InjectService("AjaxComponentEventResultProcessor")
private ComponentEventResultProcessor 
componentEventResultProcessor;

 and wrapped it via ComponentResultProcessorWrapper

private ComponentResultProcessorWrapper callback = new
ComponentResultProcessorWrapper(componentEventResultProcessor);

boolean onSuccessFromSignInForm() {
componentResources.triggerEvent("DesiredMethodName", null, callback);
}

You're triggering your own event here, so what happens after your handler  
method is exactly what you put inside your implementation of the  
ComponentEventcallback's handleResult() method. Try @Inject'ing into your  
component class ComponentEventResultProcessor and using its  
processResultValue() method passing the Block instance you've received.

Rendering Custom Component via Zone

[Times2]

Hi,

I have problem with replacing one custom component with another one via
AJAX, using zone component. Replacing first component with second should
happen on action inside first component. 
On parent page i have one block(with second component inside him) , zone
component and first component inside her(zone).

Event bubbling is working (method in the first component is invoking the
method in the parent page) but not as i was hopping to(it doesn't change the
first component with the second one).
 
Any help i can get is very much appreciated.  

Sorry for the wall of code.



//parent page

public class Index {

@Property
@InjectComponent
private Zone loginzone;

@Component
private SignUp signUp;

@Component
private SignIn singin;

@Inject
private Block loginblock;

public Block onProba() {


return loginblock;
}

}


Index.tml 

http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xmlns:p="tapestry:parameter">













SignIn.tml

http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";>








//first component

SignIn.java

public class SignIn {

@Inject
private ComponentResources componentResources;

@Component
private Form signinform;

@Parameter(defaultPrefix = BindingConstants.LITERAL)
@Property
@SuppressWarnings("unused")
private String zone;

   boolean onSuccessFromSignInForm() { 

 componentResources.triggerEvent("proba", null, callback);

  }
 
  
private ComponentEventCallback callback = new ComponentEventCallback() {

return true;

};

Re: Custom component

[Giulio Micali]

yes, the second is better If your component is a "container" for a group of
fields.
In that case, you should do it in the afterRender phase, so your method is
called after all single fields has already the new submitted values and you
can "validate" (and rollback if you want) the whole result.

Re: Custom component

[Taha Hafeez Siddiqi]

Hi Rendy

Your component, if fits the definition of a form field, can extend 
AbstractField and then override processSubmission() method.

Otherwise you can @Inject FormSupport and then use 
FormSupport#storeAndExecute() to execute a ComponentAction

Custom component

[Rendy Tapestry]

Hi All,

Is it possible to have a custom component with a method that will getting
called when the enclosing form is being submitted ? In that method, I want

Hi all,


Hi!


I have a component which in itself contains a 'ProgressiveDisplay'

Is this possible ? If so how and what should the annotation @OnEvent look

Events bubble up (from inner to outer component) and pages are components.  
All component event handler methods are the same in Tapestry, so  
@OnEvent(EventConstants.PROGRESSIVE_DISPLAY) void xxx() { . . . } should  
be enough as long as you have just one ProgressiveDisplay instance in your  
page. If you have more than one, your component that declares the  
ProgressiveDisplays should handle the events and trigger them again. I  
guess you can find some examples in the mailing list or in JumpStart.

I tried creating a custom component as you have mentioned...The problem is
the select box is not appearing on the page.  Only the label 'Test:' I
created for it appears.  Where am I going wrong?


This my tml


http://tapestry.apache.org/schema/tapestry_5_2_0.xsd";> 
Test: 

 


JAVA

public class TeamSelect {

@Parameter(required=true) 
@Property 
private Object value; 

@Inject
private ServiceFacade serviceFacade;

@SessionState
private UserSession userSession;

@Property
private long testValue;

public SelectModel getTestModel() { 
//do your lookup and return the model... 
System.out.println("serviceFacade: " + serviceFacade);
System.out.println("userSession: " + userSession);

return new IdSelectModel(new ArrayList(), "Default", 
true); 
} 
}

Im using it in a page like this - 



@Property
private Long selectedTeam;

Re: How to create a custom component

[Robert Zeigler]

Hi,

If you know how to build pages, then you (largely) know how to build 
components.  A page is just a specialized component.
Here are the main differences:
  * Components go in the .components package (instead of .pages)
  * Component templates are optional because a component may choose to do all 
of its rendering via code. However, if your component will make use of other 
components, then your component will need a template.
** Note that component templates must be in the same package as the 
component class file.
  * Components can have parameters (via the @Parameter) annotation.

So in your case, it might look something like:

CountrySelect.tml:
  http://tapestry.apache.org/schema/tapestry_5_2_0.xsd";>

  

CountrySelect.java
import ...;
public class CountrySelect {
  @Parameter(required=true)
  @Property
  private Object value;

  public SelectModel getCountryModel() {
//do your lookup and return the model...
  }
}

That's the core...

As an alternative, you could simply write a "CountrySelectModel" and just use 
 with your custom model anywhere you need it.

How to create a custom component

[hese]

Hi,

Can any one tell me where I can find a T5 example of how to build a custom
component and what the different files I should create are?

My need is - I have a select box that populates from a database (Something
like a country list...).  And I want to be able to include this select box
in any tml that I want and have the box populated with the lookup values.

Thanks!

Re: Tapestry custom component + hibernate

[Elin]

Having problems again. My packaged component is working fine except the
hibernate part.

I have my main app and a custom componet packaged into a jar. This component
has:

com.udc.mylib.entities
com.udc.mylib.pages
com.udc.mylib.services
...


When i load the packaged component, its displayed correctly into my main
application but when it comes into action and hibernate part should work, it
fails giving me an exception:

Unknown entity: com.udc.mylib.entities.Hello

(Obviously my entity is called "Hello" and its into com.udc.mylib.entities
package)



When i try to add the package with 

public static void
contributeHibernateEntityPackageManager(Configuration configuration)
{
configuration.add("com.udc.mylib.entities");
}

i get an error saying:

Use of the same entity name twice: Hello

so i suppose it was correctly loaded but somehow, it cant be found.

Any advice?

Thx in advance

Tapestry custom component + hibernate

[Elin]

Is it possible to create a component that uses some hibernate entities,
package it into a separated .jar and then import this component into my main
project being able to autocreate this new entities? 

Something like creating my custom component package following this tutorial
http://tapestry.apache.org/tapestry5.1/cookbook/lib.html

Inside that component, create the "entities" package like at any other
tapestry+hibernate project with my custom entities.

Will tapestry load those entities after adding this packaged component into
my project? so if i have the autocreate entities activated on the
hibernate.cfg.xml, those new entities will be added.


What im trying to do is an extensible application, where anyone can create
their own custom components, with the needed entities if this components
need to store their own data into the database, and being able to do this
without having to modify my main application. I just download the component
made by "someone", add it to my main project and i dont have to add the
mapping myself to my app because its included into that component. Hope you
understand what im trying to do. Would it be possible?

I would test myself but im still having troubles with components
packaging...

Re: Creating custom component

[Guerin Laurent]

In addition to the Tapestry documentation and if you use Eclipse, you should 
have a look at :
http://wiki.apache.org/tapestry/Tapestry5JSPEditorEclipse

This will provide you code completion on components in your tml files, with 
documentation on component itself and also on the component parameters.

 And don't forget that the name of the template is case-sensitive, so
 MenuBar.java -> MenuBar.tml.

The documentation needs improvement, no doubt, but this information is no

Thanks Sven,

This is exactly what i am talking about. How am i supposed to know that
something like  exists? what what else is out there? and what
else am i using the wrong way? you get my point.? I think the Hotel-booking
application should be made complicated enough to use as many tapestry

Thanks for your response. I will keep  trying.

you can also use this template code:


http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";>


   I am a menubar




the  let tapestry know, that all code between 
and 
is relevant for your component and strips all away outside this tag.

it is the better way, if you use design tools like dreamweaver or others

Hi guys;


Hi!

Don't use the  tag in components' templates (unless you're creating  
a Layout-style one).
And don't forget that the name of the template is case-sensitive, so  
MenuBar.java -> MenuBar.tml.

Creating custom component

[Josh Kamau]

Hi guys;

I  am trying to compose a page but assembling various sections e.g the menu
bar, the header and the footer as separate components.

I have my Index page which "inherits" from the main layout. Now i have made
the menu bar as follows

menubar.tml

http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";>

I am a menubar



Menubar.java

package com.josh.tcontacts.components;

public class MenuBar {

}


index page tml

http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";>






Hello world . Its now ${today}




index page java
package com.josh.tcontacts.pages;

import java.util.Date;

import org.apache.tapestry5.annotations.Property;

public class Index {

private Date today ;

public Date getToday() {
return new Date();
}

public void setToday(Date today) {
this.today = today;
}

}

How do i add the menubar to the index page? i have done the above but its
not working.

Re: Grids embedded in custom component interfer with each other

[olip]

thanks for confirming.

This seems like a serious bug and you do not need to put the grids in
components to see this not working.

If you have several grids without components on the same page the
pagerenderers do interfer each other as well!
