PowerGrids model fails during compilation in OMEdit but works fine from the command line

Description

Please try simulating PowerGrids.Examples.Tutorial.GridOperation.Controlled.ControlledGridWithReferenceCalculation, using the latest Windows nightly.

I get the following errors:

[11] 19:23:20 Error
File.open: Failed to open file PowerGrids.Examples.Tutorial.GridOperation.Controlled.ControlledGridWithReferenceCalculation_info.json with mode 2: No such file or directory

Template error: A template call failed (C:\Program Files\OpenModelica1.16.0-dev-64bit\bin\OMEdit.exe: [unknown function name]). One possible reason could be that a template imported function call failed (which should not happen for functions called from within template code; templates assert pure 'match'/non-failing semantics).

However, if I run the very same model from the test.mos script, it works fine.

I've deleted all the files in the working directory, but to no avail.

Any idea why this happens? I remember a similar issue some time ago but I can't recall if or how it was solved.

We are releasing PowerGrids as open source in a couple of weeks and planning a tutorial at the OpenModelicaWorshop, I'd be glad if we can get this to work before that.

Thank you!

Most likely because OMEdit writes the file in:

/%TEMP%/
 /OpenModelica/
  /OMEdit/
   /PowerGrids.Examples.Tutorial.GridOperation.Controlled.ControlledGridWithReferenceCalculation/
    /PowerGrids.Examples.Tutorial.GridOperation.Controlled.ControlledGridWithReferenceCalculation_info.json

which I bet is > 265 chars long MAX_PATH.

I think we need to minimize the path, not output the full model name in %TEMP%/OpenModelica/OMEdit/, maybe for starters, just the last part.

I confirm this is the path length issue.

Yeah, this came to mind to me this evening before I read these comments.

I see that for me %TEMP is currently C:\Users\Francesco Casella\AppData\Local\Temp, which already takes 46 chacters. I guess setting it to something like C:\Temp could be a reasonable workaround for the time being. Is there any easy way to do that without tinkering with Windows environment variables?

See #5796 for a proper solution

This was a dumb question, of course it's Options|General|Working Directory :)
