B4J Question CallSubDelayed causes exception for sub not found [problem fixed itself...]

Didier99 · Thursday at 8:04 PM

In a class module, I have the following code:

B4X:

Sub doStuff()
    ' do stuff...
    CallSubDelayed( Me, "setHeight" )
End Sub    ' SetRows()

Private Sub setHeight
    Log( "Height = " & frmMessage.WindowHeight )
End Sub ' setHeight

and I get this:

B4X:

java.lang.RuntimeException: java.lang.RuntimeException: java.lang.Exception: Sub setheight was not found.

In B4X, routines whose names begin with "set" and "get" are considered properties; this is probably the error. Change the name to SetHeight.

P.S.
No, this code work as expected:

B4X:

Sub Class_Globals
   
End Sub

'Initializes the object. You can add parameters to this method if needed.
Public Sub Initialize
End Sub

Public Sub DoIt
    CallSubDelayed(Me, "setHeight")
End Sub

Public Sub setHeight
    Log("set")
End Sub

are you using obfuscated release mode?
put a "_" in the sub name

Interestingly, the problem has fixed itself as I was fixing other (mundane) issues... Always makes me very uncomfortable...

On this project, I regularly get an unusual error when I recompile after making changes. I have not looked at the details (I need to) but simply recompiling again with no change allow the program to run normally, so I have not dug into that one yet.
