JS error in Calendar

[jatym]

Hi
When I'm using rich:calendar in popup mode firebug sjows error (popup dosen't show) :

invalid array length
[Break on this error] this.length--;

Error is in prototype.js on line 464.
Without popup calendar works fine, also in another page calendar works fine in popup mode, I don't know what might be wrong ?

I have had this problem in the past. What I found in my case was that I was using a component from another JSF library that was also including prototype.js but it was an older version which was causing problems.

I fixed the problem by removing the offending component from the page

Thank you slj24,
In past I was using tomahawk calendars and when I change only one for richfaces error occures.
