truncate only works local, after deploy it does nothing

Hi all,

i have strange problem. On my site i have a teaser for an article. This teaser is truncated after 200 letters. On my local machine it works perfect. After i deploy my application on the serverside, nothing is truncated.
So i looked into the files on the server if the truncate command is set and it is. So that's not the problem.

Here is the my output of the truncate command:

<%=sanitize(textilize truncate(article.teaser,200))%>

i tried to change it to something like this:

<%= truncate(article.teaser,200)%>

but nothing changed. So it's not a problem with the XSS plugin.

Has anybody an idea what could be the problem?

Thanks and Greetings
