Buildings.Examples.Tutorial.Boiler failing

[Léonard Favre]

as can be seen at ​https://test.openmodelica.org/libraries/Buildings/BuildModelRecursive.html, the following models are failing:

• Buildings.Examples.Tutorial.Boiler.System2
• Buildings.Examples.Tutorial.Boiler.System3
• ...
• Buildings.Examples.Tutorial.Boiler.System7

the error message I am getting (for System2) is the following (not very helpful):
"OMEdit - Error - Connection with the OpenModelica Compiler has been lost. - OMEdit will close."

does anyone have an idea if there is a hope it can be fixed soon?

I have none (am Modelica beginner), unfortunately. I would badly need it to work. I know Buildings is being developed using Dymola.

thanks for reading!

This usually means a stack overflow or similar crash in the omc kernel.

Yes, probably some circularity somewhere the instantiation of the model.
I'll do some debugging and see where the problem is.

Minimal model for Buildings.Examples.Tutorial.Boiler.System2.

[Per Östlund]

I added a minimal model for System2 that still fails in the same way as the full model. The issue seems to be that the Buildings library contains self-references for some reason, which our lookup has problems with. Changing line 21 in the minimal model to be just h_pTX() without the self-reference makes the model work for example. I've looked into similar issues earlier, and it's probably not feasible to fix until Adrian's new instantiation stuff is done.

This is working now (r22496). I will add a test case.
