Compatibility issues for 2024-04 release

[Fabrizio Breggia]

Hi,

I have a model written with Jaamsim 2018-05. When I try to open it now, with the last release, an error occurs:

"Fatal Error while loading file 'test.cfg': blablabla:
Entity [blablabla] may not have children

Please would you be so kind to help me?

Many thanks in advance

Open the .log file generated by JaamSim in a text editor, preferably Notepad++. This file echoes the lines in the .cfg file you loaded and shows any error messages that were generated after each line was parsed. Include the offending line in your next post to the forum.

Fabrizio,

The problem is that you have used the period character '.' in some of your object names, such as Operator1.Util. This used to be okay, but object names can no longer include a period because this notation is used to indicate the component of a sub-model. The solution is to edit your input file and use search and replace to change the names of these objects, e.g. Operator1_Util instead of Operator1.Util.
