Error parsing FMU file when it has Variable with no value

[Rolandas Ks.]

Try to parse out Controller_fmu_noWorking.fmu file and you get exception, it can not handle Variable that has no value.

Caused by: org.simpleframework.xml.core.ElementException: Element 'DiscreteStates' does not have a match in class org.javafmi.modeldescription.v2.ModelStructure at line 42

It should at least return values it can and not crash entire FMU parsing.

The error pointed out in the log you copy says that DiscreteStates is not a valid element inside Model Structure. Effectively the model description of your FMU is wrongly built. In the specs this is not valid. Here I have an extract of the definition:

I don’t see the log of the “Variable without value” that you mention. If you provide me with more information I can check.

Yeah, was discreate state, was my bad about no value. Mixed up some FMU. Thanks, will take a look at FMU then, as we have few such FMU’s
