Saving as .fsx works fine - Loading from .fsx doesnt!

Hi Forum,

I've got a question regarding saving and loading .fsx files. Right now I'm looking into ways on how to use version management in Flexsim. The XML approach with using distributed fsx files looked promising but when I am trying to load my model from a previously saved fsx file Flexsim crashes and comes up with the following error messages (system console):

Flexsim 6 (loading a fsx file from 5.1.2, as well as loading a fsx from 6.0):
exception: Exception caught in flexscript execution of VIEW:/nodefunctions/menucommands/File/openmodel line 40 instruction 97. Discontinuing execution.

Flexsim 5.1.2:
exception: Exception caught in linkedlist::loadxml()
exception: Exception caught in flexscript execution of VIEW:/nodefunctions/menucommands/File/openmodel line 44 instruction 109. Discontinuing execution.

This points to a function called:
cmdloadbyextension(str filename, num silent)

I forgot to mention that loading the same model as .fsm works fine. Any ideas on how to tackle this issue?

Cheers,
Stephan

Send sample model files to tech support (or post them here) and we'll see if we can figure out the issue.

I sent my model to tech support and although the did not find the problem straight away they pointed to the UserCommand which caused the problem. The reason is that I used hardcoded strings in my model that did not only contain letters and numbers but also control characters such as STX (0x02) and ETX (0x03). The string was used for communication with an external application.
So once I removed these characters from the string the loading procedure from .fsx works fine. The workaround to include these characters in a string is also quite easy. Instead of declaring

string str = "STX_Hello_World_ETX";

where STX and ETX are ASCII characters, the same string can be declared by using

string str = concat(strascii(2), "_Hello_World_", strascii(3));

Hope this helps if anyone encounters a similar problem.

Cheers,
Stephan
