Heh.. this is funny, but it sounds like the issue I just described in
my "Grid with multiple forms" thread. Anyway, to call a Tapestry event
from a JavaScript you probably want this in your javascript:
function yourJavaScriptMethod(yourParameterIfYouHaveOne) {
var url = '${tapestryEvent}' + '/' + yourParameterIfYouHaveOne;
var zm = Tapestry.findZoneManagerForZone("yourZone");
zm.updateFromURL(url);
}
And this in your page class:
Object onTapestryEvent(String parameterIfYouNeedIt) {
return yourBlock;
}
public String getAddToCartUrl() {
return resources.createEventLink("tapestryEvent").toURI();
}
