alltags contains Strings instead of tag-maps

[38leinaD]

I would like to print a tag-index and using freemaker. The tag-index should print the number of posts per tag. I am doing it like this:

<#include "header.ftl">

	<#include "menu.ftl">
	
	<div class="page-header">
		<h1>Tags</h1>
	</div>
	
	<ul>
		<#list alltags as tag>
			<li><a href="${tag.name}.html">${tag}</a> (${tag.tagged_posts?size})</li> <!-- THIS IS LINE 11 -->
		</#list>
	</ul>
	
<#include "footer.ftl">

I get the following error:

I am neither an expert on jbake nore freemaker but based on the jbake documentation that states that

alltags = collection of all tags used across all published content

and that

Global variable tags represent a collection of all tags. Each tag in this collection is represented by a map containing following attributes -

Expected:
I assumed that alltags would also give a map instead of tag-maps.

Actual:
alltags just contains a list of tag-strings

Is there a workaround? I.e. What is a way to get the posts for a tag? Or more specific the number of posts per tag?

This Freemarker code snippet will give you a list of tags and the number of posts for each tag:

	<ul>
		<#list tags as tag>
			<li><a href="${tag.uri}">${tag.name}</a> (${tag.tagged_posts?size})</li>
		</#list>
	</ul>

now i am feeling stupid. i did not read the documentation carefully. thanks for point out the obvious. 👍

I wrote that section and even I had to double check the code after reading it again.

Documentation can always be improved and this is one example, a code snippet under that section would help immensely. I'll raise an issue on the web site to make sure it's done.
