Error448.odt with Basic code
When running Main() in next Basic code, containing a cascade of calls with
uninitialized optional arguments, the behaviour is different between LO 6.4.5
and LO 7.0.0
Sub Main
Dim a
a = 1
SubA(a)
End Sub
Sub SubA(a, Optional x, Optional y)
SubB(a, x, y)
End Sub
Sub SubB(a, Optional x, Optional y)
If IsMissing(x) Then x = 2
MsgBox x
End Sub
In 6.4, the execution ends with the message box containing "2", as expected.
In 7.0 however, the execution aborts on the statement "x = 2" with the error
message
"Inadmissible value or data type. Data type mismatch."
The reason, AFAIK, seems to be that variable x in SubB is of type
- Variant/Error in LO6.4
- Error in LO 7.0
the latter preventing a reset of x to another value.
To reproduce the issue:
----------------------
- open the attached Error448.odt file
- open the Basic IDE
- in the Basic module of the file "Module1", run Main()
Result in 7.0:
-------------
Error "Inadmissible value or data type. Data type mismatch."
Expected result:
---------------
No error message
