[TYPO3-ttnews] My own template for tt_news

[Xatucans]

Hi, I want to create my own template for tt_news and locate it outside the
ext folder. I write this code in the TS setup field of the root page's
template

plugin.tt_news.templateFile =
fileadmin\template\tt_news\tt_news_template.html

(fileadmin\template\tt_news\tt_news_template.html is the location and the
name of the new template)
but it doesn't work.

I have tried different configurations:
1- if I include Css-based tmpl (tt_news) or Table-based tmpl (tt_news) in
Include static (from extensions)  field of my root template, tt_news gets
its default template (from ext/tt_news... folder) and shows the news with
this template


2- but if I remove them (Css-based tmpl (tt_news) or Table-based tmpl
(tt_news)) and write the code above in the TS setup field, the tt_news
doesn't work.

3- If I leave the code and Css-based tmpl (tt_news) or Table-based tmpl
(tt_news) the news appears, but they don't get my own template.

Can anybody tell me how can I do it? thanks
