Template Partial does not work on a single-entry page

Hi All,

I have a few channels for my website, the main channel (channel1) and another channel (channel2).

I’m using a sidebar in my channel1 templates which shows the titles of channel2. I set up the sidebar in a Template Partial.

The Partial displays the titles fine on the index-page of channel1 (where a number of entries are shown) but does not display on a single-entry-page (where just one entry of the channel1 is shown).

I tried using an embedded template with the titles of channel2 as sidebar. It displays fine by itself and displays fine on the index-page, but also does not display the titles on the single-entry-page.

Why does my Partial or the embedded template not display on the single-entry-page?

The Partial looks like this:

{exp:channel:entries channel="channel2" category="4" sort="desc" limit="5" disable="member_data|trackbacks"}
<div>{title}</div>
{/exp:channel:entries}

I use it on the index-page like this:

<div id="sidebar">
{template}
</div>
{exp:channel:entries channel="channel1" sort="desc" limit="5" disable="member_data|trackbacks"}
<div><a href="{title_permalink=channel1/single}">{title}</div>
{/exp:channel:entries}

I use it on the single-entry-page like this:

<div id="sidebar">
{template}
</div>
{exp:channel:entries channel="channel1" limit="1" disable="member_data|trackbacks"}
<div>{title}</div>
{/exp:channel:entries}

Any hints why this is not working as exprected are very appreciated!

Cheers, Andrea
