Suppose I wanted to trigger an action for a standard component (i.e. I
can't change the decode method), say h:commandLink. Could I do
something like this?
var params = {};
params[clientId] = clientId;
TrPage.getInstance().sendFormPost(theForm, params);

One way is:
var theForm = ... find my form through the DOM ...
var clientId = ... the client ID of the component;
TrPage.getInstance().sendFormPost(theForm, {source:clientId});
Then, on the server, in your decode, you'd just need to
check if the "source" param was component.getClientId(),
and you know it was your own component.
