Errors parsing expressions

[fmrico]

Hi!!

I am getting these errors, and I would like to know if it is really an error.

getExpr: Error parsing expresion [(and (car_assembled car1))]
getExpr: Error parsing expresion [(car_assembled car1)]
getExpr: Error parsing expresion [(and (car_assembled car2))]
getExpr: Error parsing expresion [(car_assembled car2)]
getExpr: Error parsing expresion [(and (car_assembled car3))]
getExpr: Error parsing expresion [(car_assembled car3)]

Thanks!!!

@fmrico How can I reproduce the problem? Can you circulate the PDDL domain file and the problem file or the commands to reproduce them?

I don't believe this is an actual error.

In the following code, getExpr(expr) is being called to get the expression, and it is also being used to check if expr is an expression. When it is not an expression, it prints that there was an error parsing the expression, but it is not an error. expr isn't an expression. I believe the print can be removed
