[omniORB] setting return type to be an array

[Sveta Shasharina]

Duncan,

Maybe it is a bug in omniifr?  As I mentioned in my previous
e-mail, if I use IFR methods to figure out the length
of the array, it gives (length-1)!  So to trick omniifr,
I created a type corresponding to the array with the correct
length, then the parameter was accepted and the invocation
completed.  This means that I should do the same with return
type.  If I know that it is an array, then I should create
the correct typecode and use it as a return type, rather
just taking the typecode given by IFR methods...

Sveta

OK.

You shouldn't need to do this, but it shouldn't hurt.

What exception do you get?  The IfR is not involved at all in a DII
call, so you can't be getting an exception from that. I've just tried
an example, by modifying the omniORB DII example, and it works fine
for me.

Can you post a more complete code example that shows the problem?

Cheers,

Duncan.
