some doubts on attributes flagged as 'NULLABLE'.

28 Views

Hi, all

Just encountered some difficuties. need you help.

I bound an attribute ATTR1 of NODE1 to UI element TEXTVIEW. and the type of ATTR1 is NUMC(2)

so if i dont give any value to ATTR1, the default displaying value is '00', in order to amend this 'incorrect' result, let it be 'NULL'.

I gave some code in hook method WDDOINIT

''

DATA: lr_node_info TYPE REF TO if_wd_context_node_info.

lr_node_info = wd_context->get_node_info( ).

lr_node_info->set_nullable( ).

wd_context->set_attribute_null(

EXPORTING

name = 'ATTR1' ).

''

but errors occured.

' Could not find attribute ATTR1 ?????????ꯃ扡瑳楲p'

Sinerely thank you, if you could help me ..

😊

regards,

nick.
