Comment (by liuar):

 In proj4js.js [[BR]]

 {{{
 var datumDef=Proj4js.Datum[this.datumCode]
 if(datumDef)
 {
     this.datum_params=datumDef.towgs84.split(',');
     ....
 }
 }}}
 [[BR]]

 if the datumCode is NAD27(CA-I), the datumDef will not contain a property
 named towgs84. So, to fix this problem or the workaround of this defect is
 add  "&& datumDef.towgs84" to the if clause to make sure towgs84 is
 included in datumDef.
