[Helma-user] helmaLib - Object.clone() - bug?

[robert.gaggl at orf.at]

hi klemens,

looks like you have an old version of helma.Html, because i fixed this
bug two weeks ago (see
http://adele.helma.org/source/viewcvs.cgi/modules/helma/Html.js.diff?r1=
1.5&r2=1.6)

using param.clone() unfortunately isn't possible because the param
object might be one received from a macro, and these aren't JS objects
but a mapwrapper ones, which in turn don't inherit the
Object.prototype.clone() method. that's why i switched to calling
reduce(), which clones the object into a plain JS object.

so updating helma.Html to the current CVS version should solve your
problem.

robert
