Problem saving a document

[Miklos Pocsaji <mi...@gmail.com>]

Hi!

I'm pretty new to lenya, so my question might be a beginner one.
I created a new resource type called 'headlines', it does not matter
what it is used for. I wanted to modify the content of my documents of
this doctype by adding a menu item to lenya 'Edit' menu. I named the
usecase 'hledit'. I created the usecase-hledit.xmap which matches
fine. In the matching pipeline I modify the contents of the document
and want to save it back. I realized I have to check in/out, this is
ok.
I also realized I have to call the editDocument JavaScript function in
order to make my document saved, which seemed work EXPECT when I want
to save from the CURRENT pipeline. Everything I pass as parameter
'sourceUri' works but when I assign the value
'cocoon:/request2document' to it I get the error:
<map:call function> did not send a response, at
....../usecase-hledit.xmap:109:40
(This is the line where I call the editDocument)

My questions:
 - Exactly, what does the expression "cocoon:/request2document" mean?
Is it used for what I want to (access the XML data of the current
pipeline)
 - What does the error message mean?
 - How can I solve my problem?

Thank you in advance,
Miklos Pocsaji.

It means send control to the pipeline named "request2document" in the
same XMAP.  "cocoon:/" only looks in the current XMAP.  "cocoon://"
starts at the top with the global sitemap.xmap.

If you want the XML of the "request2document" to be combined with the
current pipeline, use map:aggregate.  Each pipeline should have one
generator, zero or more transformers, and one serializer.

If you just want to reuse code without another generator, use a map:resource.

Your JavaScript function does not end with:
cocoon.sendPage("return-page");
"return-page" must be a pipeline in the same XMAP that sent the
request to the JavaScript function.  There are several methods for
sending data to the pipeline

Fix the function called in the "request2document" pipeline to return a
new pipeline.

If you need more assistance, please post the relevant code from the
XMAP and the JS.
