For some unknown reason this code only works once in linux. Works fine on windows.
This code:

<?xml version="1.0" encoding="UTF-8"?>
<media>
{def $episode=fetch( 'content', 'object', hash( 'object_id', $view_parameters.content_id ) )}
<item>
<name>{$episode.data_map.name.content|wash()}</name>
<description>{$episode.data_map.shortdescription.content|wash()}</description>
<path>
{let site_url=ezini('SiteSettings','SiteURL') file_path=$episode.data_map.file.content.filepath}
{concat('http://', $site_url, '/', $file_path)}
{/let}
</path>
<thumbnail>
{let site_url=ezini('SiteSettings','SiteURL') image_path=$episode.data_map.thumbnail.content[original].url}
{concat('http://', $site_url, '/', $image_path)}
{/let}
{/def}
</thumbnail>
</item>
</media>

is called with this url

http://www.example.com/layout/set/episodexml/(content_id)/117

works on the first request. every request after that does not get the the content_id parameter until the content cache is cleared. This is the debug error

Error: eZTemplate @ design/s2h/templates/episodexml.tpl:18[0]  	Dec 17 2005 00:39:31

using 3.7 on apache2/fedora2/php4.4

again it gets the url param the first time but will not receive the param again until the content cache is cleared

I reduced the template down to just outputing the view_parameters.myparam and it only gets passed once per variable until I remove the content cache. The permissions are set to 770 and owned by the webserver user. That part is working fine. The only error when debug is turned on is the error stating the parameter is null on the second execution. any idea what can be the problem. again the same code works fine on windows.

I've reduced everything to this and it wont take in the parameter if a cache entry exists.

{def $ep_id=$view_parameters.content_id}
{$ep_id}
{undef}

I'm getting this
Error: eZTemplate @ design/s2h/templates/episodexml.tpl:1[0] Dec 17 2005 16:12:09
Unknown template variable 'view_parameters' in namespace ''

Are any of the ez folks concerned about this one?
I would think that an issue that seems this important would get more attention.
