#6133 closed defect (fixed)

OMEdit doesn't load a library if just the version is different; no error, no warning

Reported by: rfranke Owned by: adeas31
Priority: high Milestone: 1.16.0
Component: OMEdit Version: v1.16.0-dev
Keywords: Cc:

Description

The below model is a duplicate of PowerSystems.Examples.Introductory.Units. It states uses(PowerSystems(version = "0.9.0")). OMEdit raises a notification:

[1] 11:22:07 Skripting Meldung
Skipped loading package PowerSystems (0.9.0) using MODELICAPATH C:/Program Files (x86)/OpenModelica1.16.0-dev-32bit/lib/omlibrary (uses-annotation may be wrong).

This should at least be a warning, if not an error as the model will not work.
Better: OMEdit should load the bundled PowerSystems 1.0.0 and raise a warning about the version discrepancy.
Btw: once PowerSystems has been loaded, the model checks successfully but it raises a strange error when attempting to simulate it !?

When I instantiate the model using omc on the command line it just says:

Notification: Automatically loaded package PowerSystems 1.0.0 due to uses annotation.

So it loads 1.0.0 without even indicating that it was actually 0.9.0 that was requested by the model. I don't know what OMEdit does though, it's not building for me at the moment and I haven't bothered to figure out why yet.

Btw: once PowerSystems has been loaded, the model checks successfully but it raises a strange error when attempting to simulate it !?

I get these errors:

Internal error: BackendDAEEXT.getAssignment failed because n=43>arrayLength(ass1)=43 or m=67>arrayLength(ass2)=43
Error: Internal error It is not possible to select continuous time states because Number of Equations 1 greater than number of States 0 to select from.
Error: Internal error - IndexReduction.dynamicStateSelectionWork failed!

Is this the same error that you get? It's a good idea to always write down the error you get in the ticket to make sure everyone's talking about the same issue.

No error from OMEdit. Just the notification:

[1] 13:24:04 Skripting Meldung
errorLevelToValue failed 

(besides a dialog offering the old frontend that doesn't work either though)

Ok, seems like the scripting API can't handle internal errors. I will fix it.

Fixed in 07705543. Internal errors shouldn't happen at all ideally, but at least it's better to display them than just failing when they do happen.

@rfranke, please check and close the ticket at your earlier convenience.

It's not fixed. I only fixed the issue that OMEdit couldn't display the error that occurred when trying to simulate the model, which isn't really what the ticket is about.

PR#6784 fixes the problem.

The question is should we have notification of loaded libraries on by default or not? Right now in the PR I kept it off and only enabled it for OMEdit. Not sure what is the best way to go forward? Just load uses libraries without notifying the user or show the notifications to user about the loaded libraries due to uses annotation.

comment:8 Changed 3 years ago by casella

I'm in favour of notifications for all loaded libraries on by default, including the path they were actually loaded from. This is critical information, it shouldn't be hidden in the deep recesses of the system.

comment:9 Changed 3 years ago by adeas31

  • Resolution set to fixed
  • Status changed from new to closed

Fixed with 094bb66/OpenModelica.

OMEdit loads the PowerSystems 1.0.0 when the model is loaded.
