can any FXRuby experts out there tell why i am getting this error:

 FXPopup::create: trying to create window before creating owner window.

i am trying to create a FXComboBox. it also happens trying to create a
FXListBox.

here's my line of code:

  @components[component] = FXComboBox.new(self, 1, component.lines, nil,
0, LAYOUT_FILL_X)

self is the class instance which inherits FXMainWindow. and FXMainWindow
is created on intialization.

thanks,
