Hi,
I am new to openmodelica, Since I work in reliability engineering, the main feature of openmodelica that I will use is petri nets modelling.
I've learnt about ExtendedPetriNets library (https://github.com/modelica-3rdparty/Ex … etriNets). However when I open this library in openmodelica I received several error messages which can be grouped into:

1. Class or component Ellipse not found
In modifier (Ellipse(extent = {{-100, -100}, {100, 100}}), class or component extent), class or component Ellipse not found in <Icon>

2. Duplicate modification of element Line.points on component Icon
[ExtendedPetriNets: 569:14-569:42]: Duplicate modification of element Line.points on component Icon

I suspect these error messages are due to version incompatibility between ExtendedPetriNets V 1.0 and OmEdit v1.13.2.
Hence my questions are:
1. Is it really due to version problem?
2. How to solve this problem?

Thanks.
