I am trying to fix a bug in the Animation Nodes addon.
The loop nodes has a dynamic EnumProperty and I need to select a default value. But only when the EnumProperty contains Items.
For that I need to know what the value of default is when I don't give it a value. I thought it was an empty string
selectedLoop = bpy.props.EnumProperty( items=getStartLoopNodeItems, name="Selected Loop", default="", update=updateActiveL)
but this does not have the same behaviour as if I left out the default parameter
selectedLoop = bpy.props.EnumProperty( items=getStartLoopNodeItems, name="Selected Loop", update=updateActiveL)
Does anyone know what I have to pass to default in order to have the same behaviour?
EDIT: I discovered that when I add the default parameter the EnumProperty is not created apparently because when I try to add it to the layout later it gives me this error:
rna_uiItemR: property not found: mn_LoopCallerNode.selectedLoop /home/mathieu/.config/blender/2.73/scripts/addons/animation-nodes/nodes/system/mn_loop_caller.py:66
