Description andrew 2003-08-27 17:40:48 UTC 
In one library, create two modules.
In one module, declare a public variable as an Integer.
In the other module, declare a public variable as a Double.

No error occurs and you do not know which variable you will see in both 
modules until runtime.

not API but StarBASIC

This is no error. Each module sees it's own variable.
VB also does not rise an error in this situation.
Comment 3 andrew 2003-09-06 04:10:31 UTC 
Actually, each module does not see it's own variables.

In module one, add

Public ii As Integer
Sub aaa
  ii = 3.4
  bbb()
  Print "In module one ii = " & ii
End Sub


In module two, add

Public ii As Double
Sub bbb
  ii = 6.4
  Print "In module two ii = " & ii
End Sub

When I ran this, it printed 6.4 in aaa which is not only the wrong 
value, it is the wrong type! The Private type is not a problem...

If you mark the case as resolved, again, I will not re-open it, but 
you indicated that each module sees only it's own variable. 
Unfortunately, this is not the behavior that I see. If this has 
already been modified, then slap me around a little bit, I probably 
deserve it :-)You do an awesome job Andreas!

Ultimately, I am fine with it either way. My only complaint is that 
the same variable name had different types allowing me to know which 
was which...

I have not found a way to determine which version is seen. I have not 
bothered to find a deterministic algorithm for which variable is 
recognized...

You're right, my test case was too simple. So relax, I will 
not slap you around! And thank you for the flowers... ;-)

cp: retargeted to Office-Later due to limited ressources

Another aspect of this problem is that also different Functions with the same
name are not identified correctly even if they have a different signature with
different parameters. In StarOffice we have a function
"GetDocumentType(oDocument)" in the Tools library and one "GetDocumentType()" in
the Launcher library

Reset assigne to the default "issues@openoffice.apache.org".
