Hi to everyone.
I have a class with two private strings declared in Class_Globals.
B4X:
Private ExportFolder As String
Private FtpExportFolder As String
Now I want to declare setters for those properties. This is what I do:
B4X:
public Sub setExportFolder(Value As String)
    ExportFolder = Value
End Sub

public Sub setFtpExportFolder(Value As String)
    FtpExportFolder = Value
End Sub
Now when i try to use those setters from another class, there is no autocomplete.

But if I type the commands they are accepted, and the application runs normally.
Is this an expected behavior?

(Working with B4J 7.51).

Andreas.

The Variable name and the subsignature overwrite itself.

Try name the internal vars like

B4X:
Private mExportFolder As String
Private mFtpExportFolder As String

and setters like

B4X:
public Sub setExportFolder(Value As String)
    mExportFolder = Value
End Sub

public Sub setFtpExportFolder(Value As String)
    mFtpExportFolder = Value
End Sub

Thank you both Erel and DonManfred.
After this change, now it shows ok.

But I'm a little confused about why these happened.
I saw DonManfred answer:
The Variable name and the subsignature overwrite itself.
So the getter or setter must have a different name from the property? I was thinking they was the property name with a set or get as prefix.

yes

A setter named setFtpExportFolder(Value As String) and the getter getFtpExportFolder() both point to FtpExportFolder which is a private property with the same name.
Give the getter and setter another name or rename the internal vars.

Ok.
Thank you.
Now it's clear.
