FluidTYPO3: How do I render content from other extensions (news...)? - typo3

Question

Actually I found the answer already on this site
Preferred way to add an extensions into Fluid Powered TYPO3 template
but I don't get it to work :-(
I have a page template with main content and in the sidebar content from FlexSlider extension and at the bottom I want to render the list view of extension news. So I guess answer 1a from Claus will fit:
1a) create the element in a sys folder and reference it from your Flux form settings then use v:content.render to render it by UID.
but how is that done? How do I reference it from my Flux form?
Has somebody an example code. I couldn't find a tutorial or a documentation...
Thanks for reading and hopefully you have an answer ;-)

Answer 1

An easy way is to create a typoscript element and then render it in fluid:
lib.rightcolumn = CONTENT
lib.rightcolumn {
table = tt_content
select {
pidInList = 42
where = colPos=1
}
}
<f:cObject typoscriptObjectPath="lib.rightcolumn" />
Another way is to directly create it in fluid:

Answer 2

Finally I got it accidentally by fixing another problem:
Fluid Powered TYPO3 FLUX Fluidcontent - No Output in Frontend?
I had to add the file "typo3conf/AdditionalConfiguration.php" with
<?php $GLOBALS['TYPO3_CONF_VARS']['FE']['contentRenderingTemplates'] = array('fluidcontentcore/Configuration/TypoScript/');
Thanks for help nBar, I used "f.cObject" as workaround.
Now here is my Page/Template code:
<f:section name="Configuration">
<flux:form id="homepage">
<flux:grid>
<flux:grid.row>
<flux:grid.column colPos="0" colspan="2" name="main" label="Main content"/>
<flux:grid.column colPos="1" colspan="1" name="logoslider" label="Logo slider"/>
</flux:grid.row>
<flux:grid.row>
<flux:grid.column colPos="2" colspan="3" name="news" label="News"/>
</flux:grid.row>
</flux:grid>
</flux:form>
</f:section>
<f:section name="Main">
<div class="container">
<div class="row">
<div class="col-md-8">
<v:content.render column="0"/>
</div>
<div class="col-md-4 team_logos">
<div class="infobox">
<v:content.render column="1"/>
</div>
</div>
</div>
<div class="row infobox">
<div class="col-md-12">
<v:content.render column="2"/>
</div>
</div>
</div>
</f:section>
