One solution would be to define a pseudo-continuation, just after you finish the function initialization code, which could be referred from the View page template. Something like:
function myFunc()
{
var a;
// Long initialization code here
startForm(); // Creates a dummy continuation, with no page
// being sent to the browser

Since you didn't provide the code for this startForm() function, I tried to write it myself, copying the code from _sendPageAndWait() minus the call to cocoon.forwardTo():

function startForm(timeToLive)
{
var k = new Continuation();
var kont = new WebContinuation(cocoon, k, lastContinuation, timeToLive);
suicide();
}

Do you think this would work?

Great Ugo! This should work fine, but please do let me know if you encounter any issues.

I may be wrong, but I think this needs to be:

function startForm(timeToLive) {
var k = new Continuation();
var wk = new WebContinuation(cocoon, k, lastContinuation, timeToLive);
lastContinuation = k;
return k;
}

Calling suicide() would terminate the script and since no page was sent there is no client involved to restart it.

Regards,

Chris
