Handling components event in the page that includes the component
Is it possible to handle the components event in the page that includes the
component.
Say I have a component and in that component I have two submit links with
their own id's. How do I see which link was clicked in the page that
includes the component?

Re: Handling components event in the page that includes the
component
Posted by bhorvat <ho...@gmail.com>.
Ok let try explaining everything from the top :D
I have a page called Index and in that page I have included a component
called Popup. Now this component is basically a html popup with two tapestry
links. Then I surround this component in a form and when I click the link
(the link is from the component) it submits a form. The form is then handled
in the page Index and everything is great.
What I now need is a way to tell those two links apart.Now if I put in the
page Index method
void onSelected(){
}
it is triggered for both links. What I want is to separate and to create
this method for both links. Something like
void onSelectedFromFirstLinkID(){
}
void onSelectedFromSecondLinkID(){
}
However this doesn't work. I thing that problem is that I need like the full
ID of the link. If I just use the id of the link the method is not
triggered, if I put those two methods in the component Popup then that those
methods are called. However I need those methods to be outside of component
Popup and inside page Index (so that every page can have different behaviour
for those links)
I have also tried
@OnEvent(value=EventConstants.SELECTED, component="popup.firstLinkId")
void test(){
}
@OnEvent(value=EventConstants.SELECTED, component="popup/firstLinkId")
void test(){
}
@OnEvent(value=EventConstants.SELECTED, component="firstLinkId")
void test(){
}
but non work. So what I need is to know what is the full name of the element
inside a component that is included in a page?
I hope I have explained it better :D

Hi,
I'm still not clear on what you are doing and where - did your mail client
strip out your source code example? ;)
http://tapestry.apache.org/component-events.html should explain how the
handler stuff works.

Yea I come to the same conclusion by trying to insert a method
void onSelected{
}
This method is activated, but I need to activate it with a ID so that I can
have two methods
void onSelectedFromFirst{
}
void onSelectedFromSecond{
}
However this doesn't work. So any ideas how should I call the ID of the
element inside a component included in the page?

Events bubble up in the page hierarchy afaik. So you could try to postfix
your handlers with "From<my-t:id>"
something like: onActionFromMyComponentId(...) ?

I probably din't explain it very well.
I have component with two submit links in it. I also have a page that
includes that component those two links. I need to write in that page that
includes the components the event handling for those two links but I am not
sure how. If I write handler in the Component.java it is handled but if I
write it in the Page.java class it is not handled. Is there a way to push
the event from the component up to the page?

Nice to know you got it working!
I'm still interested in the docs mentioning the custom component events. If
they are missing, it should definitely be added. (I was expecting to find it
on http://tapestry.apache.org/component-events.html)

Inject ComponentResources and poke around?

Perfect. This works. Thank you so much for your assistance.
So I can't access the link's id from the page since it is local to the
component but I can trigger an event and handle that. Great. :D
Can I ask for one more thing if it is not to much of a trouble.
Is it possible and how do I access the component's id from the inside of a
component?
Index.tml
<t:Popup id="popupForwardMessage" t:source="sectionsForwardMessage"/>
Popup.java - this is my component
@Parameter(required = true, defaultPrefix = "literal")
@Property
private String id;
I pass this id as a parameter. But is it possible to access the components
id. To avoid something like this
<t:Popup t:id="popupForwardMessage" id="popupForwardMessage"
t:source="sectionsForwardMessage"/>
So what I want is just to pass
<t:Popup t:id="popupForwardMessage" t:source="sectionsForwardMessage"/>
and then in class Popup.java I access it. But I can't do it like this
@Parameter(required = true, defaultPrefix = "literal")
@Property
private String id;
So any ideas?
