Hi
When using EOS to retrieve results from server variables, you have to take
into account that the execution is asynchronous. You have to loop until you
get a non empty result, or better use another variable to know when you can
get the values from the server. This is not necesary if you use a method
with the EOS server attribute set, as others have already said, but could
be useful for other purposes.
So your code could look like this (not tested):
method1
-----------
done:=false
Directory_path:=get 4d folder(3)
done:=True
repeat
idle
until (not(done))
method 2
------------
$p:=execute on server("method1";12345)
repeat
get process variable($p;Directory_path;$Server_Path;done;$done)
delay process(current process;10)
until ($done)
set process variable($p;done;False)
I like to put a timeout also in the loops exits just in case something does
not go as expected. Something like:
until ($done | (milliseconds > $timelimit))
