T4: From the client side, how do you programmatically update a component?
I have a use case where I need to "click on" a directllink to
updatecomponents with async=true or do an equivalent action in Javascript. I
know I can do tapestry.bind('<span jwcid=@DirectLink.../>') and it makes
some sense, but looks rather ugly. Any cleaner way to accomplish this?

Yeap, thanks Igor. I like the idea of calling the script with a parameter,
but overall a bit much compared to the one-liner on the client side, as ugly
as it may be. Adding such a component to the contrib lib or tacos might make
sense though. I'd think others might have similar needs.

Hi,
you you can do following:
-your component should implement the interface IDirect
-create a link:
public ILink getLink(){
return getDirectService().getLink(false, new
DirectServiceParameter(this));
}
- and pass the url of the link as a parameter to your Script
Map params = new HashMap();
params.put("url", getLink().getURL());
PageRenderSupport pageRenderSupport =
TapestryUtils.getPageRenderSupport(cycle, this);
getScript().execute(this, cycle, pageRenderSupport, params);
- call the url in your script
<script>
<input-symbol key="url" required="yes" />
<body>
<unique>
foo =function(){
tapestry.bind("${url}", ........);
}
</unique>
</body>
</script>
- update the components in you trigger() method:
public void trigger(IRequestCycle cycle){
getRequestCycle().getResponseBuilder().updateComponent("COMPONENT_ID")
}
Hope this helps

No - I want to trigger the update programmatically via Javascript, not from
a user's click.

I can't follow you. You want a component to update itself asynchronously
upon a user's click on a DirectLink? Why don't you just use DirectLink's
updateComponents parameter with async="true"?
