OMEdit generates bogus warnings about missing inner declarations when opening MultiBody models

[Francesco Casella]

Steps to reproduce:

• Start OMEdit
• Open Modelica.Multibody.Examples.Elementary.SpringDamperSystem

The following warnings are reported

[1] 22:59:19 Translation Warning

The following notifications are also reported:

These messages are totally bogus, since the model indeed contains an inner World world declaration. As usual, this gives an impression of overall sloppiness.

Is it possible to get rid of them?

[Adrian Pop]

I let the -d=nfAPI show all the errors and warnings so we can catch issues. I will suppress them and one could re-show them using -d=nfAPINoise.

[Francesco Casella]

Replying to adrpo:

I let the -d=nfAPI show all the errors and warnings so we can catch issues.

You mean issues with the NF API or issues with the model. In this case, the model should have no issues at all...

I will suppress them and one could re-show them using -d=nfAPINoise.

OK

[Adrian Pop]

The errors you are seeing are from fetching all the class information, annotations, type of components, inherited classes. Yes, the model would not give these errors but these are from gathering all the information. You could have a look in the omeditcommunication log to see where they are actually coming from, from which API call.

[Francesco Casella]

I still wonder why the compiler complains about the missing world component. Isn't it there?

[Adrian Pop]

Because is not for that model those messages are reported, they are reported for:
Modelica.Mechanics.MultiBody.Parts and Modelica.Mechanics.MultiBody.Interfaces.

[Francesco Casella]

Replying to adrpo:

Modelica.Mechanics.MultiBody.Parts and Modelica.Mechanics.MultiBody.Interfaces.

OK, I see. Then, it's a good idea to just suppress them for good, as you suggested.

[Adrian Pop]

Should be fixed by PR: ​https://github.com/OpenModelica/OpenModelica/pull/323
Probably some tests need updates, we'll see which.

[Francesco Casella]

Very nice, no more bogus warnings :)

[Francesco Casella]

Unfortunately, I still get some bogus messages:

[1] 11:00:45 Translation Avvertimento
[Modelica.Mechanics.MultiBody.Parts: 215:5-215:51]: An inner declaration for outer component world could not be found and was automatically generated.

[2] 11:00:45 Translation Notification
[Modelica.Mechanics.MultiBody.Parts: 215:5-215:51]: The diagnostics message for the missing inner is: No "world" component is defined. A default world
component with the default gravity field will be used
(g=9.81 in negative y-axis). If this is not desired,
drag Modelica.Mechanics.MultiBody.World into the top level of your model.

when opening Modelica.Mechanics.MultiBody.Examples.Loops.EngineV6_analytic.

[Adrian Pop]

Fixed in a42b26/OpenModelica.

[Francesco Casella]

More bogus messages: opening Modelica.Fluid.Examples.HeatingSystems gives:

[1] 23:23:07 Translation Error
[Modelica.Fluid.Machines: 400:5-400:82]: 
Medium is partial, name lookup is not allowed in partial classes.

[2] 23:23:07 Translation Error
[Modelica.Fluid.Machines: 400:5-400:82]: 
Medium is partial, name lookup is not allowed in partial classes.

[Adrian Pop]

Fixed in 03cf86/OpenModelica.

[Francesco Casella]

Double-checked, all's fine :)
