4337	OMEdit allows invalid connections	massimo ceraolo	Adrian Pop	"1) OMEdit allows two output connectors to be connected to each other. For instance allows to connect the output of two Modelica.Blocks.Source.Constant blocks, which is evidently nonsense.

2) It allows also to connect to each other input connectors, such as the input connectors of two integrator blocks.

Dymola allows 2), but rejects 1).

IMO it would be better to reject both 1) and 2); but at least 1) shouldn't be allowed, as explicitly stated in section 9.3 of specification, fourth-last bullet.


OMEdit v1.12.0-dev-229-g44b8b42 (64-bit)
Connected to v1.12.0-dev-293-gec908e4 (64-bit)

DESCRIPTION EDITED ON 21/03/2020
The situation is even worse than the original description. 
It looks like ANY connection is allowed by OMEdit when assembling components in a diagram: a mechanics.rotational flange to an input connector, a mechanics.translational flange into a rotational one, etc. Naturally, these are rare mistakes by a sane user. However, this can occur inadvertently, especially when we have components with different connector types, because of #4645 (and occurs to new users and students).
