<pre>Description:
The CallByName builtin function allows for the dynamic execution of a method
given by its name.
The arguments of CallByName are:
1. The Basic object on which to apply the method
2. The name of the method as a string
3. The call type (1 for a usual method)
4+. The effective arguments of the method
When one of the arguments (4+) is an array, then next error is raised:
BASIC runtime error. Incorrect property value.
The same error is raised when the value returned by the called method is itself
an array.
For any other variable type, including a Basic object, a user-defined type,
etc, CallByName works fine.
Steps to Reproduce:
1. In the Basic IDE, store next code in module Module1 of any (may be empty) LO
document:
Option Explicit
Option Compatible
Sub TestCallByNameArray()
Dim a,b,c,d,e,f,g
Const vbGet = 2, vbLet = 4, vbMethod = 1, vbSet = 8
Set a = Module2
b = Array(1,2,3)
c = CallByName(a, "SomeMethod", vbMethod, b)
End Sub
2. Store next code in Module2 of the same document:
Function SomeMethod(arr as Variant) As Variant
SomeMethod = arr
End Function
3. Run the TestCallByNameArray() Sub
Actual Results:
"BASIC runtime error. Incorrect property value." on the line:
c = CallByName(a, "SomeMethod", vbMethod, b)
Expected Results:
The variable "c" should contain the output of the called function, i.e.
Ayyar(1,2,3).
