What are quotes doing here:

1: <dtml-var propertyValues> 2: <dtml-var propertyValues()> 3: <dtml-var "propertyValues"> 4: <dtml-var "propertyValues()">

1 and 4 gives the same result. 2 gives Error Type: KeyError; Error Value: propertyValues(). 3 gives a >

(1) calls propertyValues() if it is callable - in this case it is, so the result is the same as (4) - otherwise it gets the value of propertyValue if it has one. (2) is a DTML error because an object cannot have a name that includes "()". An expression in double quotes is evaluated as a Python expression and the results displayed. In Python, propertyValues (without any parentheses) returns the Python object of that name. If that object is a function, it is not called (because the "()" are missing), just returned as an object. How that object is displayed depends on the type of object. Python and DTML access the same collection of objects (since DTML is using Python to do its accessing). Cheers, Tom P
