Expression builder doesn’t put quotes around a property name when that property is an argument for sumstack. Should it do so for this and any other cases like it? I realise it could go either way but the input guidelines simply talk of the argument being the name of the property to be summed, so people might get confused when the expression generated fails to work.
All property names are Strings. However, as in all Beanshell expressions, you can use the value of a property to provide a String. So using SumStack with property “Strength” and SumStack with property Strength do two completely different things, both of which are valid.
This is probably best addressed with good examples in the reference manual.
