Passing sitemap parameters between actions
Hello Cocoon sers,
I have a little problem with passing sitemap parameters between
actions, hopefully someone knowns the solution.
I have something like this in my sitemap:
------
<map:match pattern="login.html">
<!-- Authenticator writes the error message in sitemap variable
{errormessage} -->
<map:act type="authenticator">
...
</map:act>
<!-- Transformer wants to access the error message from the
stylesheets -->
<map:transform src="stylesheets/midray-html.xsl">
<map:parameter name="errormessage" value="{<???errormessage from authetificator??>}"/>
</map:transform>
</map:match>
-----
My problem is that the sitemap variable "errormessage" is not valid
outside of <map:act type="authenticator">, so i can't use it inside
transformer.
I know that this problem can be solved by doing this:
---
<map:match pattern="login.html">
<!-- Authenticator writes the error message in sitemap variable
{errormessage} -->
<map:act type="authenticator">
<!-- Transformer wants to access the error message from the
stylesheets -->
<map:transform src="stylesheets/midray-html.xsl">
<map:parameter name="errormessage" value="{errormessage}"/>
</map:transform>
</map:act>
</map:match>
---
but this solution has some disadvantages which i would like to avoid.
Any ideas?

Re: Passing sitemap parameters between actions
Posted by Jonathan Layes <j....@layes.com>.
The map object is destroyed when the authenticator action is complete
so your only option is to copy the values somewhere before the action
completes. Three places come to mind: the parent parameter map,
the request parameters and the session (assuming you have a
session). I know of SessionPropagatorAction to push values to
the session but you'll have to brew your own action if you choose to
copy to the parent map or the request parameter list. I'm not endorsing
any of these options as a good design - just pointing out what's possible.
As you already showed, nesting the transformer in the action works
and is the preferred way - try refactoring your sitemap if you can.
Cheers
