Hi John,
It seems something went wrong when you tried to add the value attribute.
The node should be converted into mixed node automatically by wizard.
- I would begin in debugger - check the attribute structure of lr_entity. Does it contain your newly added value attribute?
- You can also try to read it directly in the code (pass name of the value attribute instead of NAME):
DATA: lv_value TYPE string.
lv_value = lr_entity->if_bol_bo_property_access~get_property_as_string( 'NAME' ).
If it doesn't contain the attribute, then remove it from the node and try to add it again via wizard.
Cheers,
Pavel
