Re: about T5 javascript

here, this bug has more js that you should include.  Then you can just use:

Tapestry.activateZone( "vMessage", validLink );

I'm having problems creating a ZoneManager.  Here are is my code.

     @Environmental
     private RenderSupport renderSupport;

     void afterRender(MarkupWriter writer)
     {
         Link link = resources.createEventLink("actionFromCheck");
         renderSupport.addScript("var validLink = " + link);
     }

        public Object onActionFromCheck()
        {
                        this.message = "New Message";

                return vMessage.getBody();
        }
}

JavaScript

                        var element = document.forms[0].all("check");
                        var zoneObject = Tapestry.findZoneManager(element);
                        zoneObject.updateFromURL(validLink);

the ZoneManager is null.  I have tried serval variations on this code based
on google search. I think I need to remove the ActionLink in the component
tml file and create a new ZoneManager from the zone element and the link but
I can't get that to work ether.

URL = a url you would build on the serverside using something like:
resources.createEventLink( "".... );


Let me review the background below.. I hope I don't confuse you too much..


Normally:

<t:zone id="zoneId"/>
  activateZone


Generates:Html:

<div id="zoneId">
</div>

  URL activateZone


Generates:Javascript:

1) setup a ZoneManager against the div#zoneId
2) setup a click listener on the actionlink.. to fetch actionlink URL
from tapestry, (which calls the event listener which returns a Block,
and then tapestry renders block.. ), once the URL returns, it squirts
the contents of the results into the appropriate div#zoneId.

step 2 is basically what Tapestry.activateZone would replace.. so you
can do this without relying on an actionlink or form..

I would like to use this feature but I can't figure out what url this is.

that said, any committers want to add a simple function for people to
use?? something like this:

Tapestry.activateZone = function( zoneId, url ) {
        var zoneManager = Tapestry.findZoneManagerFromId( zoneId );
        zoneManager.updateFromURL( url );
}

var zoneObject = Tapestry.findZoneManager(elementConnectedToZone);
