[luabind] No matching overload found

[Сергей В. <iva...@gm...>]

Why luabind can't use this function?

C++ code:
Vector3f createVector3f ( float x, float y, float z );

Lua Code:
function UiControl:setScale ( value )
log ( "UiControl:setScale: " .. value )
local s = createVector3f ( value, value, 1 ) --error
self.mesh:setScale ( s )
self.mesh:update ()
end

Output:
UiControl:setScale: 1
No matching overload found, candidates:
Vector3f createVector3f(custom [f],custom [f],custom [f])

I know, this code works:
local s = createVector3f ( 1, 1, 1 )
Why it doesn't when I pass an variable?

Point me, please, where to dig.
