Description
-----------

I am getting error when I try to select WebRadioButton on form load of a
Run form in gb.web.gui version 3.18.2

The error in console is:
caught TypeError: Cannot set properties of null (setting 'checked')
    at eval (eval at answer (lib:0.0.1.js:288:11), <anonymous>:1:32)
    at Object.answer (lib:0.0.1.js:288:11)
    at xhr.onreadystatechange (lib:0.0.1.js:340:50)

Dim xx As String
 xx = Class1()

''---------Class1-----------------
Static Public Sub _call() As String
  Return Webform2.Run()
End

''----------Webform2 ---------------
Private $sValue As String

Public Sub Run() As String
  rbformA.Value = True
  If Me.ShowModal() Then Return $sValue
End

It was working fine till 3.18.1
