hello,
I want to know if is it possible to put a dropdownbykey in a table column. I want to set the possible value of the list of dropdownbykey; I can do it in a "stand alone" dropdownbykey, but if I try to insert the dropdownbykey as cell editor, nothing works. I get a runtime error I can't understand:
"You tried to access the singleton node SHOW_VIEW.1.TABLE_NODE.1.PRIO_DROP in a way other than the lead selection. "
where "TABLE_NODE" is the node where I bind the internal table and "PRIO_DROP" is the node nested in TABLE_NODE on which I created the dropdownbykey list.
I am new in web dynpro and maybe I learn some concepts in a wrong way.
with this code I fill the list of dropdownbykey:
" dropdown table elements
DATA t_value_ddbk TYPE wdy_key_value_table.
DATA wa_value_ddbk TYPE wdy_key_value.
" context node
DATA ddbk_info TYPE REF TO if_wd_context_node_info.
DATA table_info TYPE REF TO if_wd_context_node_info.
DATA node_info TYPE REF TO if_wd_context_node_info.
" get reference to nested node
node_info = wd_context->get_node_info( ).
table_info = node_info->get_child_node( name = wd_this->wdctx_table_node ).
ddbk_info = table_info->get_child_node( name = wd_this->wdctx_prio_drop ).
" fill table with possible values
wa_value_ddbk-key = '1'.
wa_value_ddbk-value = 'Alta'.
INSERT wa_value_ddbk INTO TABLE t_value_ddbk.
wa_value_ddbk-key = '2'.
wa_value_ddbk-value = 'Normale'.
INSERT wa_value_ddbk INTO TABLE t_value_ddbk.
wa_value_ddbk-key = '3'.
wa_value_ddbk-value = 'Bassa'.
INSERT wa_value_ddbk INTO TABLE t_value_ddbk.
" select node ddbk
ddbk_info->set_attribute_value_set(
name = 'CHOOSEN'
value_set = t_value_ddbk ).
can anybody help me or tell me if I misunderstood something?
thanks
Gabriele
I'm not sure the way you're getting the subnode info is allowed, I think that is the problem with your coding, unfortunately I have no system now to check it.
Try replacing this code section of yours:
" context node
DATA ddbk_info TYPE REF TO if_wd_context_node_info.
DATA table_info TYPE REF TO if_wd_context_node_info.
DATA node_info TYPE REF TO if_wd_context_node_info.
" get reference to nested node
node_info = wd_context->get_node_info( ).
table_info = node_info->get_child_node( name = wd_this->wdctx_table_node ).
ddbk_info = table_info->get_child_node( name = wd_this->wdctx_prio_drop ).
With this:
" context node
DATA table TYPE REF TO if_wd_context_node.
DATA ddbk TYPE REF TO if_wd_context_node.
DATA ddbk_info TYPE REF TO if_wd_context_node_info.
" get reference to nested node
table = wd_context->get_child_node( name = wd_this->wdctx_table_node ).
ddbk = table->get_child_node( name = wd_this->wdctx_prio_drop ).
ddbk_info = ddbk->get_node_info( ).
Let me know if this works.
Regards

I'm sorry I didn't notice this before. You DON'T need a subnode as prio_drop to create a DropDownByKey inside a table (you would need it for DropDownByIndex).
Just delete the node PRIO_DROP and put the CHOOSE attribute directly underneath the TABLE_NODE node and bind the DDK to it. Set the values over that node also.
