omniorbpy: problems sending float values

[Juergen]

hi,

I've got a problem sending floating point values to an corba server.
With other datatyes like short or string it works fine.


So having this idl file :

module Example{
interface User{
void setV( in float x );
};
interface Target{
void getV( out short x);
};
};

I just receive zero ( -2.58265845332e-05) by sending an float to
another client with the above interface.
the client :
*************** *************** *************** *************
import sys
from omniORB import CORBA
import _omnipy
import Example, CosNaming

orb = CORBA.ORB_init( sys.argv, CORBA.ORB_ID)



ior = sys.argv[1]
obj = orb.string_to_o bject(ior)

us = obj._narrow( Example.User )

if us is None:
print "blabla"
sys.exit(1)

us.setV( 5.0 )
*************** *************** *************** *************

the server :
*************** *************** *************** *************
import sys
from omniORB import CORBA, PortableServer
import CosNaming, Example, Example__POA

class User_i( Example__POA.Us er ):
def setV( self, x ):
print x
print type(x)
y = float(x)
print y
print type(y)


class Target_i( Example__POA.Ta rget ):
def getV( self ):
return 5

orb = CORBA.ORB_init( sys.argv, CORBA.ORB_ID)
poa = orb.resolve_ini tial_references ("RootPOA")


us = User_i()
tg = Target_i()

uo = us._this()
to = tg._this()
print orb.object_to_s tring(uo)
print
print orb.object_to_s tring(to)


poaManager = poa._get_the_PO AManager()
poaManager.acti vate()

orb.run()
*************** *************** *************** *************

does anyone have an answer to that kind of problem?
I mean, it just like sending short values, or strings.

It works fine for me with floats, too. You'd better ask this on the omniorb
ML, and don't forget to give some more details on the python & omniorb & OS
versions you're using.

I never used omniorb and have no clue were's the problem,
but if you don't find a solution just convert float into a string
on one side and back on the other hehe =B)

Upgrade to the latest stable release, omniORB 4.0.7 and omniORBpy 2.7.
The problem you are seeing is due to a conflict between some
marshalling code in omniORB 4.0.6 and your compiler's use of strict
aliasing.

Cheers,

Duncan.
