Sorted column is not styled - no 'active' class on TD

I know you aren't updating 5.x any more, but that's the version I found this bug on so maybe it applied to 6.x too.

After changing to using advanced forum I noticed that the 'active' class is never applied to the cells in the sorted column of the topic list any more. It is only applied to the header. So our forum lost the nice background colour we apply to sorted columns.

I believe this is because you are calling tablesort_header() in advanced_forum_preprocess_forum_topic_list, but you never call tablesort_cell for the individual cells. Probably because you are using a template file to print the cells, whereas normal forum does it all in a function.

So I had to do the following to get it working:

In advanced_forum_preprocess_forum_topic_list():

// Create the tablesorting header.
$ts = tablesort_init($forum_topic_list_header);
$variables['sort'] = $ts['name']; // <<< Add that line

In advf-forum-topic-list.tpl.php template file you need to insert the active class in each cell (views count cell cannot be sorted) like so:

<td class="title<?php if ($sort == t('Topic')) print ' active';?>">

<td class="replies<?php if ($sort == t('Replies')) print ' active';?>">

<td class="created<?php if ($sort == t('Created')) print ' active';?>">

<td class="last-reply<?php if ($sort == t('Last reply')) print ' active';?>">

Sorry for no patch file.
