T4: Adding a listener to a link that has not been rendered in tapestry
I wrote a component which shows some html from an external source. This html may contain some links. If one of this links is clicked I need to call a listener to set some parameters, but I don't know how to trigger the listener in this case.
Please help.

AW: T4: Adding a listener to a link that has not been rendered in tapestry
Posted by Ka...@materna.de.
Thanks so far. In my freemarker-templates I wrote the links as if they would have been renderered by DirectLink. Now Tapestry uses the trigger() Methode of the Direct Interface. No real nice solution, but it works.

depends on how much control over the "external links" you do have.
If you can control their generation, you can do anything ;).
hard to say, without a more concrete knowledge of what these links should do,
why they cannot be generated by tapestry and what they may be allowed to know
about tapestry.
DirectService, as all services has a method to generate links to call it. So, if you can
call this, you're fine

RE: T4: Adding a listener to a link that has not been rendered in tapestry
Posted by Ka...@materna.de.
We are using Tapestry 4.02 in a portal environment. So using AJAX or javascript (even so it may not be barrier-free) is not so easy. I thought about something like writing my own service or subclassing DirectService, or something like that...
Any suggestions?

you could use the EventListener mechanism to intercept the clicks,
see http://tapestry.apache.org/tapestry4.1/ajax/eventlistener.html
If you know the link-id's in advance, it's particularly easy.
If you don't have control over the "external" links, you'll have to
come up with some javascript delegating the onclick events to a single
element controlled by tapestry which you can then intercept.
