Tapestry 5 and Event component.
I am getting this error when clicking on my "searchbutton". What is my
problem exactly ?
"Request event 'clicked' (on component Gentoo:button) was not handled; you
must provide a matching event handler method in the component or in one of
its containers."
gentoo.tml :
<t:button type="button" t:id="button" value="search" event="clicked" />
gentoo.java :
@Component(parameters = {"type=button"})
private Button button;
@OnEvent(component = "button", value = "clicked")
public JSONObject onButtonClicked(String value) {
System.out.println("Event Caught !");
}
Thanks

Create the event link for your own page, and then obtain the target page and
invoke a method on it.

i have an admin page that creates a link that would reside on another

It seems that Button is not designed for ajax.
I wonder why you don't try block/zone?

Ok, it seems to come from the parameter "String value" in my onButtonClicked
statement. I removed it and the event is now handled. However it appears
that I am not allowed to return a JSONObject from the OnButtonClicked
method. May be is it not possible with this kind of component.
But perhaps you can still help me. I am trying to make a research function
for my interface. For the moment, it works great with the following code :
gentoo.tml :
<t:textfield t:id="textfield" t:value="textFieldValue" t:mixins="OnEvent"
event="blur" onCompleteCallback="onSearchRequest" />
gentoo.java :
@OnEvent(component = "textfield", value = "blur")
public JSONObject onBlurEvent(String value) {
System.out.println("Event Caught !");
String translatedValue = "Package not found !";
try {
String category=applicationManager.getCategoryFromApplication(value);
if (category != null) {
translatedValue = "This package is located in category
<strong>"+category+"</strong>.";
}
return new JSONObject().put("translatedValue",
translatedValue);}
catch(Exception e){}
return new JSONObject().put("translatedValue", translatedValue);
}
gentoo.js :
/* This is to update the Textfield component 'result' */
function onSearchRequest(response) {
$('result').update("Search result(s) : "+response.translatedValue);
}
My problem is that the search is performed on "blur" event (when the user
click anywhere outside the textfield box) whereas I would like to perform it
when the user click on a button instead. So that is why I believed I could
trigger this event by changing the "blur" event into a "clicked" event.
Does anyone know how I can simply do that ?

I just tried t5commons component's Button component, it works. I think the Button in t5commons should be the same as CK lib because CK originates from T5commons.
<t:commons.button type="button" t:id="button" value="search" event="clicked" />
void onClicked() {
System.out.println("I can get it.");
}
I don't use annotation here, but they should be the same.

Here is the component reference :

Indeed the parameter "value" is useless. So I remove it. But it does not
work.

I don't have source of ck lib.
What about removing the parameter 'value' of the method?
BTW what does the parameter mean?

Actually I did. I first tried to use it with the OnEvent mixins, but the
problem was the same. Then by checking on the ck component reference, I
noticed that the component <t:button> has already a parameter named "event".
That's why I removed the parameter "mixins".
I have just tried again with Try <t:button type="button" t:id="button"
value="search" mixins="ck/OnEvent" event="clicked" />, and I got the same
exception.

You haven't used the ck/OnEvent mixin in the button, so the event is not fired.
Try <t:button type="button" t:id="button" value="search"
mixins="ck/OnEvent" event="clicked" />

Thanks for your quick answer. I tried to rename this method "ButtonClicked"
instead, but it did not fix the problem : the request event is still not
handled.
Any other idea ?

I suspect Tapestry got confused because your method is both the naming
convention ("onButtonClicked") and has @OnEvent ... and they are in
conflict. Rename the method to not start with "on".
