Re: Actionlinks with the same t:id

[Kristian Marinkovic]

i guess you are using a loop to generate a unordered list. 
just place the eventlink into the loop and everything should be fine :)

Hi Kris,

Thanks for the response. Using EventLink I need to have:

private EventLink menuItem1, menuItem2, menuItem3....

with t:id="menuItem1" etc in the tml. So still a declaration for each
link in java and a different t:id each time but yes it does mean only
one handler method.

Cheers

Use a EventLink instead and define a custom event.

@Component(parameters= {"event=menu", "context=menuContext"}
private EventLink link;


somewhere else (a parent component):

onMenu(....)
{}

The t:ids within a component/page have to be unique.

Hi,

I have a menu, with 5 to 10 links, each of which I'd like to be an
actionlink to trigger a zone update. 

I'd like to have just one event handler for the menu, something like:


public Object onActionFromMenu(int context) {
 
... get new results per the context...
 
   return resultsZone.getBody();
}


with my menu like:


<li>
  <t:actionlink t:id="menu" context="literal:1" zone="resultsZone">...
</li>
<li>
  <t:actionlink t:id="menu" context="literal:2" zone="resultsZone">...
</li>
...


However Tapestry complains, saying that t:id should be unique. If t:id
has to be unique, that means I have to have separate event handlers for
each menu item, which is a little verbose. 

Is there a way of having multiple actionlinks in a page, each triggering
the same event handler? This is also useful if I want to have the same
link more than once in the page.

Thanks

Richard.
