Thanks guys! I have a lot of components that are re-used either in loops, or just embedded in multiple components (often in the same page).
The pattern that Paul and Thiago are suggesting works fine if that component occurs a single time on a page. However, if you use it multiple times, the client side zoneId (as well as the Tapestry JS initializers) are not unique any more, which causes the same zone to be updated all the time, no matter which EventLink got the click. Example Page.tml: <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd";> <t:component/> <t:component/> </html> Component.tml: <t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd";> <t:eventlink t:id="link" zone="aZone">click me</t:eventlink> <t:zone t:id="aZone" id="aZone"> ${counter} </t:zone> </t:container> In this case, no matter which link you click, the first component will get updated because the zone in the first and the 2nd have the same client side id. Hence my looking around for a solution that would allow me to do this in .tml only as per my original mail. "component:" seemed to be a solution as per the documentation (see below), but doesn't do the trick. In other words, it would be nice if there was a component binding that did the equivalent of this: .java @InjectComponent @Property Zone aZone; .tml "prop:aZone.clientId" Cheers!
