Tapestry 5.2 offline documentation
Hi. I've just download tapestry-src-5.2.4. How can I generate documentation for offline reading? Should I run "mvn site" on every subfolder of tapestry-src-5.2.4 ? I've got the following error when running "mvn site" inside tapestry-src-5.2.4/tapestry-project: [INFO] Trace org.apache.maven.reactor.MavenExecutionException: Could not find the model file 'C:\java-lib\tapestry\tapestry-src-5.2.4\tapestry-project\tapestry-json'. for pr oject unknown It looks like maven is searching for "tapestry-json" inside "tapestry-project" folder. How to tell maven that "tapestry-json" folder is on the same level with "tapestry-project" (not inside "tapestry-project") ? Thanks in advance. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: T5: Progress indicator and AJAX example?
Hi,
Here is a simple example
Java Code :-
import org.apache.tapestry5.BindingConstants;
import org.apache.tapestry5.ComponentResources;
import org.apache.tapestry5.Link;
import org.apache.tapestry5.MarkupWriter;
import org.apache.tapestry5.annotations.AfterRender;

import org.apache.tapestry5.annotations.Import;
import org.apache.tapestry5.annotations.Parameter;
import org.apache.tapestry5.internal.util.CaptureResultCallback;
import org.apache.tapestry5.ioc.annotations.Inject;
import org.apache.tapestry5.json.JSONObject;
import org.apache.tapestry5.services.Request;
import org.apache.tapestry5.services.javascript.JavaScriptSupport;
@Import(library = "progressbar.js")
public class ProgressBar {
@Parameter(value = "1", defaultPrefix=BindingConstants.LITERAL)
private int period;
@Parameter(defaultPrefix = BindingConstants.LITERAL)
private String clientFunc;
@Inject
private ComponentResources resources;
@Environmental
private JavaScriptSupport javaScriptSupport;
@Inject
private Request request;
@AfterRender
void afterRender(MarkupWriter writer){
Link link = resources.createEventLink("timer");
JSONObject spec = new JSONObject();
spec.put("url", link.toAbsoluteURI());
spec.put("period", period);
spec.put("clientFunc", clientFunc);
javaScriptSupport.addScript("new ProgressBar(%s);", spec);
}
Object onTimer(){
JSONObject spec = new JSONObject();
double value = 0.0;
try {
value = Double.parseDouble(request.getParameter("value"));
}catch(NumberFormatException nfe){
return spec;
}
CaptureResultCallback callback = new
CaptureResultCallback();
resources.triggerEvent("update", new Object[]{value}, callback);
value = callback.getResult();
System.out.println("Value = " + value);
spec.put("value", value);
return spec;
}
}
JavaScript Code :-
ProgressBar = Class.create({
initialize:function(spec){
this.value = 0;
this.url = spec.url;
this.clientFunc = spec.clientFunc;
this.executer = new PeriodicalExecuter(this.execute.bind(this),
spec.period);
},
execute:function(transport){
new Ajax.Request(this.url + "?value=" + this.value, {
method:"get",
onSuccess:function(transport){
this.onSuccess(transport);
}.bind(this)
}, this.period);
},
onSuccess:function(transport){
var json = transport.responseText.evalJSON();
if(typeof(json.value) == "undefined"){
alert(transport.responseText + ": returned")
this.stopExecuter();
}
this.value = json.value;
if(this.clientFunc){
var func = this.clientFunc +"(" + json.value+")";
eval(func);
}
if(json.value >= 100){
this.stopExecuter();
}
},
stopExecuter:function(){
this.executer.stop();
}
});
Usage :-
updateFunc = function(percentage){
$("progressBar").update(percentage + "%");
};
Hope it helps

Re: Ajax custom exception handled does not work in tapestry 5.2.4
Can you provide an example of an exception that is not being handled?
Are you talking about javascript exception or java exception?

RE: Image file upload with Easy FCKEditor
Hi, did you ever get a workaround for this? From looking around I can see
there are various fixes involving .htacess files / mods to php config but
was hoping there was something obvious within Easy FCKEditor itself ...

Subject: Image file upload with Easy FCKEditor
Hi All,
I cannot work out how to get images to upload using the Easy FCKEditor
component in Tapestry.
I have created a fresh project, just to test this, using Tapestry 5.2.4,Easy
FCK Editor 1.0.5 and the server is Tomcat 6.0.26 [currently being run from
Eclipse Helios].
To set this up, I have [almost] followed the instructions on
http://t5-easy-fckeditor.kenai.com/Installing.html with the exception of
setting the version number to 1.0.4
Following through the above site's very clear tutorials, in the section on
'Supporting File Uploads', as soon as I try and do anything like upload a
file or browse the server, I get error messages ("The server didn't reply
with a proper XML data") or my browser asking me what to do with this PHP
file that it's been given. I have never been treated to the error message
that is illustrated on the page.
Apologies if this has been answered before - on searching, I can find a few
questions, but no answers that make any sense to me.
Regards,
Alex C

Re: Prevent double submission w/linkSubmit
I haven't spent a ton of time thinking about your specific problem, or why you can't disable the link, but it reminded me of an old thread about canceling link submits. http://tapestry.1045711.n5.nabble.com/quot-Confirm-quot-mixin-won-t-cancel-when-in-zone-td2436465.html If you can't disable the link then maybe you can just ignore the clicks.

Re: Prevent double submission w/linkSubmit
Instead of trying to disable every element that can trigger a form
submission, I stop the form submission event itself. Here is the JavaScript
I have been using, and it seems to be working for me:
document.observe("dom:loaded", function() {
$$("form").invoke("observe", "submit", function(event) {
if (this.submitted) {
event.stop();
} else {
this.submitted = true;
};
});
});

Right - and as I stated in my original post I tried disabling the link by observing the FORM_PREPARE_FOR_SUBMIT_EVENT event - but for some reason you can't disable the link like you can a button...

Hi!
A flash persisted value is cleared when it's read from the session,
something that happens once per request AFAIK. What you see it that AJAX
requests are processed in one request, while non-AJAX action (including
form submission) requests are handled in two (redirect-after-post, one for
handling the action, another for rendering a response). I guess we need
something like a "renderflash" persistence, that removes the object from
the session after a render request, AJAX or not, is finished. Meanwhile,
try setting your field to null in a @PageDetached method.

T5: When Flash persisted values are cleared?
Hi all, i'm slightly confused with @Persist("flash") and XHR requests.
I have a Message component which used to show alert/warn/info messages on
the page, it has a message property, which is flash persisted:
@Persisted("flash")
private String msg; //+ getter and setter
On several pages it wrapped to Zone, like this:
And the page event handler doing something like:
public Object onActionFromCopy()
{
messages.setMsg("Complete");
return new MultiZoneUpdate("toolZone",
toolZone).add("messageZone",messages);
}
if actionFromCopy() called via XHR request message is shown, but if i then
refresh page (non-XHR) the message is shown once more and i don't see
that FlashPersistentFieldStrategy.didReadChange(..) is called during first
XHR.
I'd like to use messages component with both XHR and non-XHR requests.
What i'm doing wrong?
Thanks.

T5: Progress indicator and AJAX example?
Hi, Can anyone point me to an example of a progress indicator or, more simply, how one would go about having a page with a % complete field? I have a process that ingests a file and takes quite a long time and I would like to indicate to the user how much of it has been done. I recall from research I did a few months ago that there is a progress bar in one of the T5 component archives but there are no examples as to how to use it and I'm not even sure if it works. I imagine that if I wanted just a simple field on a page that updated with a % then I would have Javascript make an AJAX get and obtain a value from the server. However, as I'm a complete newbie to AJAX, an example of how to do this would be extremely helpful. Example silly questions: does my field have to be in a Zone? Or aren't Zones relevant seeing as I would be making the AJAX get in my own Javascript. Also, would the % value updated by my process just be held in a @Persist field? Anyway - some pointers or hints would be greatly appreciated. Regards, c.

Hi All, I have a simple page with a component in it. This component contains a zone. I would like to be able to update the zone from the parent page.
