Domino Designer / : circular use of script libs

Idea:

Why does code like this (Visitor Pattern):

class User

sub invite(b as Visitor)

b.visitUser(me)

end sub

sub doSomething()

end sub

end class

class Visitor

sub visitUser(a as User)

a.doSomething()

end sub

end class

work in one class lib, but not when seperated into two libs ("Illegal Circular use")?

This makes some OOP concepts (in this case Visitors, which call the User back) impossible when seperating code into different libs or you get huge script libs (ls.doc only work with so long libs and it also means you touch all code when you just want to change one bit).

Please make this error go away!

Comment: Agree, problem's been there since R5 and does impose unnecessary constraints when trying to build modular script library designs.

Comment: First, your code doesn't compile. It has two errors.

Second, you can use two libraries just fine.

UserLib
Class User
Sub invite(b As Variant)
b.visitUser Me
End Sub
Sub doSomething()
End Sub
End Class

VisitorLib
Class Visitor
Sub visitUser(a As Variant)
Call a.doSomething()
End Sub
End Class

Agent Visitor Test
Options
Use "UserLib"
Use "VistorLib"

Sub Initialize
Dim User As New User
Dim Visitor As New Visitor

Call Visitor.VisitUser( User )
End sub

Comment: @3: this is using variants, so is not compile save :-(
