Re: Passing a parameter to flow from sitemap

Thanks for the detailed reply. Actually, I want to pass a session attribute value to flowscript.

I am using this syntax:

<map:parameter name="myid" value="{session-attr:myID}"/> But this gives the same error as the one I describe below.

(I know the value is not null because I can pass the same
parameter to a stylesheet and it shows up OK).

Is there a "magical" way of doing this, too?

In flow:

cocoon.session.getAttribute("myvar");

if myvar is a session attribute.

Thanks

(PS And does the code shown in the manual actually work as written??)

If you want to pass 'global' parameters to flowscript, then you can define them as sitemap globals and access the global input module from flowscript.

in sitemap:
<map:component-configurations>
<myvar>blabla</myvar>
</map:component-configurations>

<!-- to pass to XSLT -->
<map:parameter name="myvar" value="{global:myvar}" />

in flowscript:
importPackage(Packages.org.apache.cocoon.components.modules.input);
var global = cocoon.getComponent(InputModule.ROLE + 
"Selector").select("global");
var myvar = global.getAttribute("myvar",null,null);

Cheers,

This should be a trivial operation, but is not working:

As per the manual (http://cocoon.apache.org/2.1/userdocs/flow/sitemap.html), I have:

Sitemap:
<map:script src="script/dbtest.js">
<map:parameter name="test" value="foo"/>
</map:script>

In dbtest.js:

//param - below is line 33....
var thisTest = cocoon.parameters.test;

which results in this error:

An Error Occurred
Cannot convert null to an object.
org.apache.avalon.framework.CascadingRuntimeException: Cannot convert null to 
an object.
cause: TypeError: Cannot convert null to an object. (file:/.../dbtest.js; line 
33)

Any ideas how to succesfully pass a parameter to flow?

Thanks
Derek
