Arrays Validation Rule 20116

[leandrohw]

Arrays validation needs to be updated. It is not checking validation rules correctly. A major problem is when SBaseRef points to an array and the object doesn't have index objects. The validator is not finding the expected error, which should indicate SBaseRef should deference to a scalar object.

Hi @draeger and @leandrohw
I have opened a PR (#290 ) to address this! I implemented the missing validation logic for rule ARRAYS_20116.

The JSBML validator now correctly checks SBaseRef objects during the general consistency phase. If it finds an SBaseRef that points to an element with a ListOfDimensions, it enforces that the SBaseRef must also provide a ListOfIndices to dereference it to a scalar object, throwing the proper error if they are missing.
