FMU Unable to Find File on Resource Folder in Windows

[Arinomo <trista.arinomo@…>]

I exported an FMU with included text file as Resource. File was correctly place in resource folder. When testing the FMU with fmuChecker.win64 fatal error occur as shown below. Persumably because the wrong use of "/" instead of "\" in windows environment.

Ouch, it seems we somehow combine the current directory with the resources directory and with the path to the file in a bad way on Windows. Probably some regular expression issues.

Hi Adrian, do you have any further information about this issue? thanks

[Adrian Pop]

Should be fixed by: ​https://github.com/OpenModelica/OpenModelica/pull/301
Please test with the nightly from tomorrow, or do you have a test model so I can test with it?

Hi Adrian,

thank you for the fast fix.

Sadly i can'not uplod file from work. I'll try with the nightly build tomorrow night and will let you know on monday if it works.

It seems that the resource file still could not be found.

[Adrian Pop]

The path to the table file is correct now. The problem seems to be something else, the name of the table is somehow wrong and it says:
Table matrix "estPack\TestFolder\TestFile.txt" not found on file ..... I guess the name of the table should be something else and is overwritten by the name of the file. I'll debug this a bit with: ​https://github.com/modelica/ModelicaStandardLibrary/blob/master/ModelicaTest/Tables/CombiTimeTable.mo#L591

Another nasty bug found, this PR should fix it:

Thank you very much, Adrian. This fixed the issue and the FMU could be check using fmuCheck.win64, so this i think this ticket could be closed.
