 Hi to all,

 If I execute this query

 {{{
  SELECT
 ST_InterpolatePoint(geom,ST_Transform(ST_SetSRID(ST_MakePoint(-3.17287857984195,40.7322588249179),4326),3042))
  FROM roads as rc
  WHERE idvia = '666XX';
 }}}

 The result is

 {{{

 ERROR:  ST_InterpolatePoint: 1st argument isn't a line


 ********** Error **********

 ERROR: ST_InterpolatePoint: 1st argument isn't a line
 SQL state: XX000
 }}}

 Is there a way to workaround and transform MULTILINESTRINGM to LINESTRINGM
 without loosing the measure?

 Thanks a lot
