Adrien PROKOPOWICZ reported a new bug.
Summary
---
Nested WITHs : Cannot use the WITH variable shortcut in child WITH's expression
Type : Bug
Priority : Medium
Gambas version : 3.9.90 (TRUNK)
Product : Language
Description
---
In less confused terms, it means the following construct will not work at
runtime :
With obj
.A = 69
With .T2
.B = 42
End With
End With
It fails at the second With's declaration with the error : "#12: Not an
object", although the expression "obj.T2.B = 42" alone is valid and works well.
You can see the full code running here :
https://gambas-playground.proko.eu/?gist=7404d762b30f40b129f8f6faa8fbe19e
In the example the construct in the TestYes() function works, but the TestNo()
fails with the above error.
I also looked at the compiled code generated by the compiler (see attached),
and it seems that the bad function tries to load the variable's value from a
different stack location (see line 9), which could explain why the interpreter
finds a bad value.
(This is pure speculation since I know close to nothing about the Gambas
bytecode, but I thought it might help)
