B4J Question Sleep and CallSubDelayed (is it a limitation or a bug?)

[Cableguy]

I have somewhere in my code a CallSubDelayed line... It all works as expected, unless I put, in the called sub, a sleep statement...
Then, the called sub becomes resumable and the CallSubDelayed errors stating something about a "void" value...
In the warnings I get the line complaining about a "possible coding error" and that it will be converted to string...

So, this is a limitation with resumable subs, or a bug?

You should post the relevant code and the exact error message.

I will do so later today...
But just try it, a simple CallSubDelayed (Me, "mysub")
And in my sub, try a Sleep (500)...

This works as expected:

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("1") 'Load the layout file.
    MainForm.Show
   
    CallSubDelayed(Me,"Sub1")
End Sub

Private Sub Sub1
    Log("Here")
    Sleep(500)
    Log("awake")
   
End Sub

In b4j, any statement after mainform.show is not executed, or am I wrong?

 

[stevel05]

That is not correct.

 

[Cableguy]

Ok, but have you tried to place it before the main form show method?

 

[stevel05]

I have now, it still works OK. The main form is very light (just one button), but the callsubdelayed call will cause sub1 not to be called until the AppStart sub has finished, wherever it is placed.

strangely, I am unable to reproduce it either, so, I guess EREL should Close this thread
