Damn... A woohoo'd a bit too early as I tested with a simplified version.
setTimeout(
function() {
print('Generating value proposition ' + id); //This works
just fine as there is no dependency on the environment --> Cocoon object
}, index * 3000);
setTimeout(
function() {
print('Generating value proposition ' + id);
cocoon.processPipelineTo("write-map-and-topics/" + id, null,
new Packages.java.io.ByteArrayOutputStream()); // This runs into an exception
as the main function returns quickly and my closures can't get hold anymore of
the current environment
}, index * 3000);
Caused by: java.lang.IllegalStateException: Unable to locate current
environment.

Not sure yet if my problem is solvable ;-(

Works nice !!
function generateValuePropositions() {
var id_collection =
Collection.fromArray(getJson('getCommaSeparatedBasicTypeIds'));
print('Starting generation of ' + id_collection.getLength() + ' value
propositions!!');
var index = 0;
id_collection.forEach(
/** we write the map and topics for each id **/
function(id){
//We delay invocation of the pipeline with 3 seconds
setTimeout(
function() {
print('Generating value proposition ' + id);
cocoon.processPipelineTo("write-map-and-topics/" + id, null,
new Packages.java.io.ByteArrayOutputStream());
}, index * 3000);
index++;
}
);
cocoon.sendPage('index.html');
}

I found a nice article on stackoverflow showing how to create my own
implementation in flowscript. I will of course first need to thoroughly test
it but it looks promising so far ;-)
var setTimeout,
clearTimeout,
setInterval,
clearInterval;
(function () {
var timer = new java.util.Timer();
var counter = 1;
var ids = {};
setTimeout = function (fn,delay) {
var id = counter++;
ids[id] = new JavaAdapter(java.util.TimerTask,{run: fn});
timer.schedule(ids[id],delay);
return id;
}
clearTimeout = function (id) {
ids[id].cancel();
timer.purge();
delete ids[id];
}
setInterval = function (fn,delay) {
var id = counter++;
ids[id] = new JavaAdapter(java.util.TimerTask,{run: fn});
timer.schedule(ids[id],delay,delay);
return id;
}
clearInterval = clearTimeout;
})();

Hi guys,
I was bulk processing DITA maps and topics from flowscript and noticed that
following code is executed parallel. So basically the cocoon.processPipelineTo
returns immediately so it seems. This results in max sessions reached to XMLDb
and I run into an exception. Just checking what is best way to put some delay
in the execution.
function generateValuePropositions() {
var id_collection =
Collection.fromArray(getJson('getCommaSeparatedBasicTypeIds'));
print('Starting generation of ' + id_collection.getLength() + ' value
propositions!!');
id_collection.forEach(
/** we write the map and topics for each id **/
function(id){
cocoon.processPipelineTo("write-map-and-topics/" + id, null, new
Packages.java.io.ByteArrayOutputStream());
}
);
}
Kind regards,
Robby
