Plugin crashes with "Unknown function html_escape called"

[Russ Brown]

When attempting to run the plugin, I get the following error in the trac log:

I am running trac trunk, and updated to the latest version a couple of days ago.

What version of ClearSilver are you running? That function was added 0.7.0.

[Russ Brown]

I had 0.9.7.

Upgrading to 0.10.2 fixed that problem, thanks.

However, the timelone now shows no data, with nothing in the error log.

I encountered the same problem in 0.10.

I've got the same problem in Trac 0.10

I managed to patch it with this patch to not do any escaping:

     <?cs each:e = timeline.events ?>
-    <event start="<?cs var:e.date ?> <?cs var:e.time ?>" title="<?cs var:html_escape(e.title) ?>" link="<?cs var:e.href ?>" icon="<?cs var:e.icon ?>"><?cs var:e.message?></event>

     <?cs /each ?>
 </data>

It works now, with these problems:

• Initial view centers on wrong date, I have to scroll alot to find any data
• No icons on items

Note that the simile timeline code is no longer under active development.

Obsolete and removed.
