Unary operator precedence ignored by ASTNode parser.

[danv61]

Given this expression (konm * (h ^ - 1.0) / koffm), parsing it with the ASTNode parser will result in an error for the unary operator.
The following equivalent expression will parse correctly: (konm * (h ^ (0.0 - 1.0)) / koffm)

When i try this, it works as intended:

formulaToL3String(parseL3Formula(' (konm * (h ^ - 1.0) / koffm)'))

yields: konm * h^-1 / koffm

Can you let me know what functions you used?

I am using ASTNode math = ASTNode.parseFormula(expr); This is the exception I'm getting: org.sbml.jsbml.text.parser.ParseException: org.sbml.jsbml.text.parser.ParseException: Encountered " "-" "- "" at line 1, column 15. Was expecting one of: <INTEGER> ... <NUMBER> ... <EXPNUMBER> ... "(" ... "{" ... <STRING> ... <STRING> ... <STRING> ... "{" ... at org.sbml.jsbml.ASTNode.parseFormula(ASTNode.java:1112) I am using jsbml 1.6.1?

Hello Dan, this makes it apparent, that this is an issue with the jsbml project, so there is not much i can help with here. I'll try and transfer the issue to the other project and hope that @draeger or @niko-rodrigue will be able to look at this soon.

Are you sure this was completed? It's been moved to the jsbml project, and I don't see a duplicate in the issues list.

Sorry assumed if it had been moved it could be closed here

I had the same error with jsbml-1.6.1-with-dependencies.jar.
Is this still not fixed?
