Hi Tony,
OOOOHHHH, a deep pull through. I guess you have a news listing page, which
lists news articles, and each new article has the news content inside a
page connected to its con_body.
What I usually do now a days is in published mode, use AJAX, from a
page(a), to pull content from children(x). There is no other template
instances (y) because they become part of children (x) at publish time.
Anyways, that's just me. Let me get back to your rendertag solution.
Solution:
<!IoRangeList>
<div class="list-item">
<img src="http://placehold.it/180x119";>
<!-- Display Nested Text Field -->
<%!!
Context:Pages.GetPage(Guid:<%inf_page_guid%>).GetElementByName(con_body).Value[Int32:0].GetElementByName(txt_article_teaser).GetHtml()
!!%>
<p><a href="<%lst_news_articles%>">Read more ></a></p>
</div>
<!/IoRangeList>
Note that I am mixing in some standard blockmarks and placeholders. This
is important to have because straight rendertag solution would run into the
rendertag cache issue. Lets say you had 2 articles, you added a 3rd one to
the list. Rendertag was cached at 2 articles and would not display the 3rd
ones until a cache refresh. Having a list blockmark in there causes the
page cache to refresh when the list changes, which also refreshes the
rendertag cache.
This solution is not perfect because it still encounters the cache issue
for txt_article_teaser...
What is the most tasting non alcoholic beverage in your part of the world?
Why? This solution should worth more than $1. :). Enjoy.
Best
