Hi Bruyn,
there is a continuation input module, that you can use inside the
sitemap to pass any continuation information to any object (an xsl, a
flow, a custom object of yours). For example, to pass the continuation
id as a parameter to an XSLT you can simply write :
<map:transform src="my.xsl">
<map:parameter name="contid" value="{flow-continuation:id}"/>
</map:transform>
The syntax of the input module is xpath based, so to obtain for example
the id of the parent continuation you can use
flow-continuation:parentContinuation/id . You can find the javadocs for
the input module class here
http://cocoon.apache.org/2.1/apidocs/org/apache/cocoon/components/modules/input/FlowContinuationModule.html
.
Regarding bizdata, they are live only within the request, so once you
have serialized the page (or PDF or whatever else) they are lost, but
all you need is still in the flow, so once you get back there using the
continuation id ...
Hope this helps,
Simone

When a continuation is created by sendPageAndWait, where is it stored?
Can I access it with flowscript or in the sitemap?
I have a scenario similar to the 'flowscript continuation from external
reply' problem discussed recently. What I'm trying to do is iterate
over a list, and for each item in it, call out to some remote process
that will render a 'PDF Form' with my continuation-id in its submit
button. So something like the following:
//for each element in the list
for (var i=0; i<subjects.size(); i++) {
//get some more input, if you want
var subject = subjects.get(i);
bindFormInput("subject", subject, {subject:subject});
//format xml input via jx generator
var dom = pipeline.processToDOM("4pointsresult.xml", {doc:doc,
subject:subject});
//let some other pipeline do stuff and a sendPage (actually another
top-level flowscript function)
cocoon.sendPageAndWait("forms-server.flow", {dom: dom});
//and then move on to the next element
}
I guess I could stick a jx template in the middle, grab the
continuation-id from there, and then post a form to my flowscript, but I
don't see how I'd preserve my bizData (dom) across requests like that...
And if the continuation os available to the jx generator, shouldn't I be
able to get to it without going thru all that?
TIA,
Bill Bruyn
