Thanks, Thiago. With your help, now the method looks like this:
Object onAction(String pageAndBlock) {
String[] sb = pageAndBlock.split("/");
if (request.isXHR()) {
Block b =
cs.getPage(sb[0]).getComponentResources().getBlock(sb[1]);
if (b != null) {
return b;
}
}
return sb[0];
}
it works. However, the solution is still a little ugly. As you see, I have
to manually split the parameter to get the page and block names. I tried the
two-parameter method: Object onAction(String page, String block), but
tapestry failed to call it. Because when tapestry renders the page, it
encodes the slashes in the context attribute of the actionLinks, resulting a
link like "Index$002fcontent" rather than "Index/content" as I wrote in the
template. So when tapestry receives the request, it calls the one-parameter
handler, rather than the two method one. How to prevent this (encoding of
slashes) from happening?
