raw-request-param

[Richard Lewis <ri...@fastmail.co.uk>]

Hello Cocooners,

I am implementing a search engine for my Cocoon site as a Java servlet.
All Cocoon has to do is send the search terms from an HTML form to the
servlet and then send the results through a stylesheet:

<map:match type="request-parameter" pattern="search">
    <map:generate
    src="http://localhost/search?terms={raw-request-param:search}" />
    ......
</map:match>

It works, except when the request parameter 'search' has a space in it,
it is passed on as "term1 term2" where it should be "term1+term2". This
causes the sitemap to break because there is a space in the map:generate
src URI above.

Does anyone know whats wrong with this?

Cheers,
Richard

This is not possible, by design. Cocoon pipelines are two stages, 
construction and execution. During construction of a pipeline you can 
alter the components that are used, but during execution you cannot. 
Thus, you cannot alter the structure of the pipeline based upon the data 
passing through it. If you need to do that, you probably want to be 
using flowscript in some way as your controller, and then choose your 
pipeline based upon your decision.

Passing a value from a transformer to the sitemap

[Eran Fuchs <er...@mdrm.com>]

Hi all.
I'm trying to send information from a transformer (or any other sitemap
components) back to the sitemap.
I need to extract and process a value from the piped xml, and control the
flow according to it.
I have tried using the request-attr output module, but the change seems to
be only noticeable inside components (following components as well) , and
does not seem to propagate to the sitemap itself (the sitemap still uses the
old value, when used as {request-attr:my-value}).
Any ideas?

Thanks,
  Eran

raw request parameter module does not work and will not work due to the 
servlet specs. You should nest two input modules to make it work: 
request parameter module and url encode module.

Example:

<map:match pattern="remote-action">
	<map:generate 
src="{global:skid-url}?LIC_ID={url-encode:{session-attr:userid}}&amp;KH_KOD={url-encode:{request-param:contractor-code}}"/>
	<map:serialize/>
</map:match>
