I am creating a form and then calling a function and getting the system to wait. I'm calling from the form and not a service like this:
The skeleton for the function is contained in my GlobalFunctions file and looks like this:
The function runs fine, but when it comes back to the calling module, I get the following error:
I don't think I'm doing anything unusual. Does anyone have any experience with this?

B4X:
wait for (GlobalFunctions.ParseCycleCount(lJson,lSAPData)) Complete (Result As Boolean)
If Result=True Then
btnOK.enabled=True
btnCancel.Enabled=True
Msgbox2("Local Data Successfully Updated","Info","OK","","",Null)
Return
Else
Return
End If
The skeleton for the function is contained in my GlobalFunctions file and looks like this:
B4X:
Sub ParseCycleCount(pFile As String, pSAP As String) As ResumableSub
Dim lResult As Boolean =False
... Do Stuff
Return True 'If it works, otherwise False
End Sub
The function runs fine, but when it comes back to the calling module, I get the following error:
B4X:
