Re: Component that displays additional "containing Page" markup
Grid is much more powerful than I knew. Thank you guys for nudge in the right direction. I will be sticking with my component for this particular page, but I am replacing allot of other code with Grid. did the trick and works like a charm. Cannot believe I didn't see it earlier. Thanks again, Bogdan. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Component-that-displays-additional-containing-Page-markup-tp5718622p5718742.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Component that displays additional "containing Page" markup
The other limiting thing I remember about the Grid component was that I could only display one "Object' per row. I could not do: Object1.Name Object2.NameObject3.NameObject4.Name Object5.Name Object6.NameObject7.NameObject8.Name As you can tell, I did not look at the Grid component for a long time now. I'm at work and cannot test it out. Can't wait to get home :))). Believe it or not, I am working on a "legacy" Struts application for a client. Painful stuff.

Re: Component that displays additional "containing Page" markup
Pagination is the reason for not using the Grid component. I want to paginate my results without holding anything in memory (session). For Grid I will select the entire set, @Persist it and then display portions on the page. What I am doing is a bit different. I always select the (number of tokens I need to display) +1 by using SQL Limit A,B. If I have NumberOfTokensToDisplay +1 in the list it means there is another page, if not, well not :). The only thing I need to compute is nextPage number, which I put as context to Next eventLink. Much cleaner in terms or resources then holding an entire list of results in memory, and no cleanup required when I'm done. Thank you Lance, I'll have a look at your demo.

Re: Component that displays additional "containing Page" markup
Thank you both for replying. Now that I read it after a day, my question is not very clear. Here is a more to the point explanation. My custom component will take care of pagination. This means I need my component to wrap around a Loop in the main page. The Loop will be iterating over a List of results. The code I am hoping for is: http://tapestry.apache.org/schema/tapestry_5_3.xsd";> --> tapestry Page html that displays list entries I will explore the suggestion.

Component that displays additional "containing Page" markup
Hello everyone,
How can I allow "Page" information to be part of the component markup
output? Take for example the zone component:
--> component
this is the time on day ${timeOfDay} -> this value comes from the Page
containing the component
When I write my own component, how can I pass additional "data" to be
included in the rendering of this component?
I would like to write:
maybe a loop here that would read a list in the Page containing the
component, and display it.
Thank you,
Bogdan.

Re: Tapestry 5 book : some minor typos in Chapter 2

Re: Update other zones on zonerefresh event
Thanks very much for your reply. The missing part for me is the method which
will capture the server side "zonerefresh" event. What is this method
called? :))
There are three solutions for me:
1) a method similar to -> onZoneRefresh() { invoked when zonerefresh does
it's XHR request. I would use this method to update all other zones in the
page. } --> This would be my preferred way.
2. zonerefresh mixin will contain an expansion like: ${message} which will
invoke the server side
getMessage() { and do the refresh of all pages zones here}
3. intercept the request early in the process tree, verify if it is XHR and
maybe some context info from zonerefresh mixin and if the correct page
update all zones. --> least preferred way
Given the awesome flexibility on Tapestry i would assume there is a method
name ( like onActionFromZoneRefresh or onZoneRefresh ) that will be called
server side when the mixin refreshes. Similar in nature to the method
"onEvenName()" linked to an EventLink component. Trouble is, I cannot seem
to find this method name :).
Thanks,
Bogdan.

Update other zones on zonerefresh event
What I want to achieve is a "self refreshing cluster of zones" for a notification mechanism driven by the autorefresh event of a zonerefresh mixin. To simplify, a multiZoneUpdate that is triggered by a zonerefresh event from the mixin. How do I capture the "zonerefresh" event from the mixin inside a tapestry method where I could call AjaxResponseRederer and update all the other zones on the page. Is this even possible, given that all the other zones, which are not self refreshing, will not have an event that links them to the request?

JSON request construct in Tapestry
I am trying to open Jira tickets directly from my application using
atlassian's REST api. For this I need to create a JSON request and submit it
to some Jira handled URL. Can I construct such a request in Tapestry? It's
somewhat backword in that Tapestry becomes a client to the request.
Assume here that I will be using some third party library to construct the
JSON request, I just need Tapestry to submit it. If not, I will be falling
back to java's own http api.
More concrete: I want to submit string -> {"fields": {"project": {"key":
"PC"},"summary": "My remote created task", "description": "Creating of an
issue using project keys and issue type names using the REST API",
"issuetype": {"name": "Task"} } }
to some URL that accepts JSON :).
Thanks,
Bogdan.

InjectPage into a service
Hi everyone,
Is there a way to inject a page into a service via InjectPage annotation?
I am trying the following and does not seem to work:
package com.myapp.services;
public class MyServiceImpl implements MyService
{
@InjectPage
private Login loginPage;
public Object consumer()
{
loginPage.getLoginForm().recordError("too-soon-change-email");
return loginPage;
}
...
}
So, myPage get's MyService injected and calls consumer() method. When
consumer() tries to getLoginForm() is throws null pointer.
===
I also tried passing to the service consumer() method a loginPage instance
injected in "myPage" as an argument, like this:
public MyPage
{
@InjectPage
private Login loginPage;
@Inject
private MyService worker;
onActivate()
{
worker.consume(workToBeDone, loginPage);
}
}
In this case I get a more "exotic" error.
Any ideas how I could make use of a page in a service?
Thanks very much,
Bogdan.

HttpSessionListener interface implementation by Tapestry5 component
Hi everyone,
When a user logs out I want to remove it from my online_table. This can
happen in two ways:
1. The user clicks LOGOUT link and I remove him from the online_table and
invalidate his session.
2. The users simply closes the browser, in which case I am unaware that he
left and the session will be invalidated by the container after a certain
interval.
In case 2 however, when the container disposes of the session I want to
capture it and based on it's attribute, remove the user from the
online_table. I'm using Tomcat so I do this by implementing the
HttpSessionListener interface in one of my components. This component is a
Layout component that I use to wrap around my pages.
When the container kills the session it correctly invokes my method:
@Inject
private OnlineUsersControler onlineUsersControler;
@Override
public void sessionDestroyed(HttpSessionEvent arg0) {
onlineUsersControler.removeUser(//get user credentials
here); -> it throws NULL POINTER because the onlineUserControler has not
been instantiates by the @Inject annotation
}
As you can see the OnlineUserControler is a Tap5 service. It looks like when
Tomcat invokes my sessionDestroy method, Tap5 does not also fulfill the
@Inject contract. I guess it happens because the page get's called by Tomcat
and not Tap.
Is there a way for me to force Tap to inject my service? Any other work
around idea is welcomed. I have even went so far as to putting a finalize
method in the User object to be removed and calling System.gc() on
sessionDestroy ( i know ridiculous ).
Thank you,
Bogdan.

EventLinks and their handlers
I am stuck on a rather silly operation. I have an eventLink in the tml and
it's event handler in the class like so:
tml ->< a t:id='postConversationLink'>click the link < / a >
class ->
@Component(parameters = {"event=postConversationEvent"})
private EventLink postConversationLink;
@OnEvent(value="postConversationEvent",
component="postConversationLink")
void valueChosen()
{
System.out.println("annotated version");
}
void onPostConversationEventFromPostConversationLink()
{
System.out.println("convention version");
}
To me both the annotated version and the convetion version look correct.
However, for both i get the error: Request event 'postconversationevent' ...
was not handled.
>From the message it looks like the link is actually generating the event,
but somehow it cannot be matched to any of the two handlers.
Thank you,
Bogdan.

dynamically change the context information of an EventLink on the cliient side
Hi All, I would appreciate your help with some ideas as I am trying to implement a chat component and I want to use Tap for the server page. The user will add text to a text input and click a link or hit enter. At this point I need to send what the user entered to the tapestry class. It would be ideal if I could use a Zone with an EventLink to take advantage of Tap built in Ajax Support. The problem with this though, is how do I add what the user entered as text to the context of the link. How to make the user entered text reach the EventLink's method parameter. Is this more workable than an 100% JQuery client that simply posts requests to a Tap5 page? Thanks very much, Bogdan. -- View this message in context: http://tapestry.1045711.n5.nabble.com/dynamically-change-the-context-information-of-an-EventLink-on-the-cliient-side-tp4972710p4972710.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Importing a JQuery library stops Zones from responding to events from EventLink
Hi all,
I have a page in which I declare a zone:
@InjectComponent
private Zone tokenDetailsZone;
an EventLink for updating the zone:
@Component(parameters = "event=updateContent","zone=tokenDetailsZone" })
private EventLink updateContent;
and the event handler method:
Object onUpdateContent(Integer packageId) {
// perform logic
return tokenDetailsZone.getBody();
}
The TML has all the necessary content for the zone to be displayed.
All this works fine.
However, when I add a javaScript library to the page like so:
@Import(library={"context:js/jquery.min.js","context:js/fancyzoom.min.js"})
public class PageClass
{
...
}
It stops working. By "stops working" I mean the EventLink in the template
get's displayed, but when I click it the Event Handler method
"onUpdateContent" no longer get's invoked.
I have tried adding the javaScript library not by @Import but by using
"JavaScriptSupport", still the same problem.
Anything I'm missing here? Why importing an additional JS library interferes
with the zone's update?
Thanks very much,
Bogdan.

Re: removing attributes from session from pages other than the one setting it
I solved it another way: Page X persists the session object. Page X also defines a method which invokes componentResources.discardPersistentFieldChanges. I navigate to page Y. On page Y I @InjectPage X and, at the appropriate time I invoke the method on page X that discards all persistent data and return a redirect link to page X. Being that the discard process removes session data for all subsequent requests of page X, returning a Link from page Y will give me the exact behavior that i need.

Re: removing attributes from session from pages other than the one setting it
Yep, it does not solve my problem. Being on another page than the one setting the object in session, discarding will not remove my object of interest. Still digging for a solution. I wonder if I could just cast the session back to a Servlet HttpSession and just invoke removeAttribute from there. That will be leaving Tap scope a bit, so i'm reluctant to do it that way. -- View this message in context: http://tapestry.1045711.n5.nabble.com/removing-attributes-from-session-from-pages-other-than-the-one-setting-it-tp4592795p4592891.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

removing attributes from session from pages other than the one setting it
Hi again everyone, I have hit another snag. Page X contains a session persistent field: @Persist private ArrayList paginatedResults; I am navigating away from page X to page Y. On page Y I want to remove the persisted object "paginatedResults" from the session. I am looking at the Tap Session Interface and it seems to be missing the removeAttribute() method of HttpSession. If I were on page X, the one that actually persists the object, i would use discardPersistentFieldChanges method from ComponentResources, but I am not. What would be the solution for me to remove the persisted object from session?

Re: Javascript library not loaded into the page via @Import
Thanks for the reply. The sure way of determining that my js is not making it into the page is that i'm not seeing the side effect. My js will modify the width/height of the jpg images on the page.

Javascript library not loaded into the page via @Import
Hi all,
In my Tap app I have a simple js file which contains:
This library resides under: Web-Content/assets/js/test.js
The page for which I want to import this library has the following
annotation above the class declaration:
@Import(library="context:/assets/js/test.js")
public class MemberHome {
...
}
If I change the library name, Tap5 complains the file does not exist, so I
assume it is indeed reading it when the name's match.
However, after launching the app, when I look in the page source the library
does not exist. Somehow Tap is not complaining about not finding the file,
but it does not include it in the page.
Is there something obvious that i'm missing here?
Thanks very much,
Bogdan.

resource shared accross threads
Hi again, I have a Index class which declares another object as a private instance variable: private User user = new User(); This object will hold some attributes of the user. It's constructor will populate it with default values. Index template has the ability to update the attributes inside "user" object. Issue is that all other threads will see the updated attributes, and not the default ones i was expecting. It looks like the same instance of "user" is shared across all application requests ( user constructor is invoked only once). Shouldn't Tap clean all variables every time a new request is serviced? Clearly I'm missing something here.

getter/setter for textfield component
Hi all,
I have a textfield component inside a loop. The value of the text
component is set like this:
The entire loop is enclosed in a . When i try to submit the form, I
get the following error:
An exception has occurred: Failure writing parameter 'value' of component
Index:textfield: Expression 'getValueForKey(for_value)' for class
com.example.tutorial.pages.Index is read-only
My Java class does contain a setter method:
public String getValueForKey(String key) {
return arUser.getValueForKey(key);
}
public void setValueForKey(String key) {
System.out.println("DO NOTHING");
}
The only funny thing i'm doing here is that the java class does not have a
property "per se", only getter and setter methods.
Thanks very much,
Bogdan.

perthread or singleton
Hi, I have a Tap5 service called QueryFactory. This service will include dozens of methods for database interaction: selects, inserts, updates etc. This being an Web App, potentially multiple users ( threads ) will have the service injected at the same time and "potentially" invoke the same method. Which path should I take: - make the service perthread? -> not really a fan as the class could become big and multiple instances can eat up memory. - go with singleton and synchronize all the methods inside it? As the methods return void and do not change any shared variable, they are basically atomic operations even without the use of the synchronized keyword. Any suggestions?
