In the below code, the line marked by
%%% b tries to install the functor X at a remote
machine foo.
When the functor is called in the following
block 'local ... end',
it failed with the error message:
% type error
% Expected type: class
% At argumen: 1
% In statement: {Object.newObject <Resource> _<optimized>}
% Call Stack:
% procedure in file ".../bar.oz", in line 10, column 3, PC= nnnn.
--------------------------------------
If I replace the line %%% b with the line %%% a,
i.e.
the functor is installed locally,
then
the same block 'local ... end' can run successfully.
[ note: both local and remote machines are Sun Sparc
with SunOS 5.10
and have Mozart-oz version 1.3.2 ]
Can anyone help me out here ?
THanks
