Re: ActionLink context help
Hi,
Others will surely correct me if I'm wrong...
- Ideally you should be able to create a mixin for the onclick event
on the actionlink that picks up the value of the textfield and sets
the context before the tapestry actionlink event triggers. However
since the actionlink is tied to a zone this is not so trivial.
Something to do with indeterministic ordering of events in javascript
i believe
I can see a couple of other alternatives;
1. Event and a little javascript using prototype and its inbuildt
support for ajax requests. Haven't tested the below so a big
disclaimer here :-)
A) Sample Javascript - checkusername.js;
CheckUserNameLink.prototype = {
initialize: function(elementId, requestUrl)
{
this.elementId = elementId;
this.requestUrl = requestUrl;
Event.observe($(this.elementId), 'click',
this._click.bindAsEventListener(this));
},
_click: function(theEvent)
{
var url = this.requestUrl + / + encodeURIComponent($
('userName')); // adding the username as a context param to event
new Ajax.Request(this.requestUrl, {
method: 'get',
onSuccess: function(transport) {
var isTaken = transport.responseJSON.isTaken;
if (isTaken === 'true') {
// javascript to tell user the username is take... update a div/
span or whatever
}
}
});
}
};
B) In your TML
remove the zone/replace with an empty div/span or whatever
a href=# id=d=verifyDuplicatedUserName${message:verify-username-duplicated-link
}/a
C) In your page class
// above class definition
@IncludeJavaScriptLibrary({context:js/checkusername.js})
// inside class body
private static final String CHECK_USER_NAME_EVENT = checkusername;
@Inject
private RenderSupport renderSupport;
@Inject
private ComponentResources componentResources;
@AfterRender
void afterRender() {
Link link =
componentResources.createEventLink(CHECK_USER_NAME_EVENT);
renderSupport.addScript(new CheckUserNameLink('%s', '%s');,
verifyDuplicatedUserName, link.toAbsoluteURI);
}
@OnEvent(value = CHECK_USER_NAME_EVENT)
public Object onVerifyUserName(String userName) {
//... do whatever you need to verify if username is taken
// return result as json
JSONObject response = new JSONObject();
response.put(isTaken, isTaken);
return response;
}
2. Autocomple: You might use the autocomplete mixin for textfield ?
...have to be creative to make it user friendly though ...

I'm still getting started with Tapestry by doing some stuff, but...
many
questions.
This one is in regards to AJAX. It's a How to kinda question.
I Have a form like this in my page.tml:
form t:type=form t:id=registrationForm clientValidation=false
t:label for=userName /
input t:type=TextField t:id=userName value=user.name
t:validate=required,
maxlength=15, minLength=3 size=15 /
t:zone t:id=userNameDuplicatedNotice${userExistMessage}/t:zone
a t:type=actionlink t:id=verifyDuplicatedUserName
context=literal:testing
href=# t:zone=userNameDuplicatedNotice${message:verify-username-duplicated-link
}/a
input type=submit value=${message:label.submit.create.user} /
/form
What I'm trying to figure out is: What is the best way to give the
current
value of textfield userName to the context of the link
verifyDuplicatedLogin?
Let me try to express with a user story:
As a user I want to introduce a user name and click in a link to
automatically(AJAX) receive a message informing me if the userName
is
already taken or not
Thank you,
jp

Also is i interested jQuery and Tapestry advance examples. Once you get over the conflict of $, it should in theory be straight forward... check out the wiki on howto enable jquery. Let me know if you find any good examples of cool jquery plugin integrations for tapestry ! And is there possible switch off tapestry javascript and write fully my own javascript? Search this forum for disable javascript (somebody asked the same not to long ago) Is there any particular reason you wish to fight the framework ?

Try injecting PageRenderLinkSource and use
createPageRenderLinkWithContext

streamresponse actionlink and zone problem
Hi, I have a page with a left hand listing of reports and a righthand zone showing details for the reports when clicking reportlinks in the listing. In the zone I have an actionlink for downloading a pdf version of the report. When clicking the links in the listing the zone updates correctly. But as soon as I click and download a pdf, the report-links on the lefthand side seizes to work. To get them working again I have to refresh the page. Using firebug I can see that the actionlink posts and receives the correct response, but the zone is never updated. Tried debugging the Tapestry Javascript but can't figure out where exactly it fails. (It does enter ZoneManager.updateFromURL, but never invokes ZoneManager.processReply) I've used the following wiki page as inspiration for returing the pdf: http://wiki.apache.org/tapestry/Tapestry5HowToStreamAnExistingBinaryFile anyone got any ideas ? regards Magnus - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: streamresponse actionlink and zone problem
Cheers,
Thx for swift reply.
- Not using zone param in the actionlink for downloading the pdf though.
I can't post the complete code (as its a whole lot going on :-)
The page has the following layout;
- Left column; Listing reports. Each report represented by an
actionlink with zone param=reportDetails (t:actionlink
t:id=selectReport context=report.id zone=reportDetails$
{report.name}/t:actionlink)
- Right column: Showing details about a report. The details are
wrapped in a zone reportDetails. Inside the zone is an actionlink to
download a pdf (t:actionlink t:id=downloadPdf${message:report-downloadPdf
}/t:actionlink)
the page class has the following code for the actionlinks mentioned
above;
// download pdf
StreamResponse onActionFromDownloadPdf() {
/* this code basically constructs a pdf and returns a
StreamResponse, as described in http://wiki.apache.org/tapestry/Tapestry5HowToStreamAnExistingBinaryFile
*/
return new PDFTransformer().generatePDF(report);
}
// actionlink for returning reportDetails Zone
Object onActionFromSelectReport(int id) {
Report report = reportRepository.findById(id);
return reportDetails.getBody();
}
not much magic in this. Obviously since the page has lots of other
stuff, this could be the cause,
I might have to make a simpler page to isolate the problem, but was
hoping that maybe someone else has stumbled upon a similar scenario...

Hi Magnus,
I can't quite oversee your situation correctly, but it sounds like
you have might have set the zone parameter on your actionlink for
downloading your pdf. If your link returns a stream, tapestry cannot
add the required JSON needed for appropriate zone handling and
consequently obstructing the next zone updates. If this is the case,
remove the zone parameter from your downloading link and it should
work fine. Otherwise, post your code.

Re: streamresponse actionlink and zone problem
Cheers,
tried a little more to figure it out. Made a dead simple page, but the
same problem.
So I just rewrote the actionlink to a pagelink to a new page using
target=_blank. That works, but flickers a little.
The new download page returns the streamresponse in onActivate.
thx

I think your pdf download will be upsetting your page state in some
way. I generally choose to make a separate page to handle downloads.
Otherwise isolation seems the way forward I would say and focus on
the debuging javascript and the errors you might get there.

autocomplete mixin within zone problem
Hi, I´m experiencing javascript errors when using the autocomplete mixin in a zone. (found the following closed issue that I added a comment to : https://issues.apache.org/jira/browse/TAP5-260 ) Seems there is a problem (at least for me) when using autocomplete inside a zone, doing something (other than submitting form with autocomplete field) that refreshes the zone and the autocomplete field has focus. A javascript error (element is null) is generated. Anyone else experiencing the same problem ? Any suggestions for a workaround ? cheers magnus
Re: mac os x gzip compression 5.1
Cheers, I found the culprit. It appears that T5.1 has changed the way java scripts are included in head. I had included a javascript conditionally in my Layout.tml; head t:conditionalcomment t:condition=lt IE 7 script type=text/javascript src=/myapp/js/iehover- fix.js/script /t:conditionalcomment /head This rendered a tag !--[if lt IE 7] script type=text/javascript src=/myapp/js/iehover-fix.js/script ![endif]-- However all my included javascript references including tapestrys own was added inside this conditional... so it worked for IE6... but firefox obviously had rather poor js support for zones etc. I.e :-) a minor gotcha that I should have noticed earlier.
