PowerBuilder v12.1, b7055


I'm attempting to implement multi-threading.
I created the object INV_AUTORPT and got everything working in a single-threaded mode.

In the Instance variables of the frame:
u_nv_autorpt                inv_autorpt                        // AutoRpt processing object

The initialization is called from the frame in the function of_check_for_autorpt(). The following single-threaded invocation works perfectly:
IF (NOT (IsValid (inv_autorpt))) THEN
   // Single-threaded invocation    
   inv_autorpt = CREATE u_nv_autorpt


When I replaced the single-threaded invocation with the following code....
errorReturn        lret_rc

IF (NOT (IsValid (inv_autorpt))) THEN
    
    // Multi-threaded invocation
    lret_rc = SharedObjectRegister ("u_nv_autorpt", "AutoRpts")
    IF (lret_rc = SUCCESS!) THEN
    . . . more


....it fails first with this:


....and then with a SharedObjectCreatePBSessionError! error; my message is:



Any ideas on why that first error is occurring????


Thank You,

Olan
