JSCalendarContrib version released 22 Jul seems broken

So it is just me, or did the version of JSCalendarContrib I upgraded to today broken? Basically I see:

in my logs, and think i have tracked it down for form date rendering in /lib/Foswiki/Form/ which seems to come from JSCalendarContrib, and seems (to my eye) to have a reference to expandMacros method about line 51. I can't find this any where. I see is it not in the SVN repo under the 1x06 and 4632 etc. branches, which I think corrsepond to 1.06.

Is it just me?...

You are not alone

I think the problem is in lib/Foswiki/Form/ This file was overridden by JSCalendarContrib. With this version of Date, I got your error when I try to attach the following simple form into a topic
| *Name*  | *Type*  | *Size* | *Values* |
| Date  | date | | |

Yeah, it seems whoever uploaded it did a very silly thing. We've been bitten by something we've been fearing for a long time: we don't have (yet) a way to keep several versions of a plugin, and especially tag versions for releases. Here, the currently available version of JSCalendarContrib from is the one in the Subversion repository from trunk, which is for the next Foswiki version (most probably 1.1). As 1.1 had some major internal re-factoring, and this is a core plugin, there are incompatibilities. What could be done is code some compatibility fallback in the plugin, but it will soon become cumbersome.

Anyway, I think the only safe way here is to upload back the JSCalendarContrib from the release branch, and for the poor felows who have already upgraded, hum... try to get it back then?

So basically, the version you installed is for 1.1, and you're running 1.0.6 (as it's the latest released Foswiki version).

Let us know here if you need more help rolling back.

It was plainly a mistake that the plugin was uploaded to Extensions web from trunk.

I have restored a 1.0.X version.

A task has been raised to request this extension made backwards compatible. It is not necessary that JSCal is not compatible from 1.1 to 1.0
