At line 99 of FormulaRenderer, the object relating to the formula is cast as an OperationPtg. At line 100, getNumberOfOperands() is called on it. Examining the type hierarchy, getNumberOfOperands() is abstract in OperationPtg, and the only subclass that implements it that doesn't return a constant is AbstractFunctionPtg, which returns _numberOfArgs, a private byte. The constructor sets _numberOfArgs on creation by casting an int argument nParams as a byte. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
