how to add created element to node?

[Former Member]

hi experts,

I am having node structure like this :

CLAIM <--- NODE

CLAIMITEM <--- NODE

EXPENSETYPE <--- NODE

expvar <--- ATTRIBUTE

DATEVAR <--- ATTRIBUTE

i m BIND ing node CLAIMITEM to datasource property of table control , having two fields expensetype as dropdown and date.

i am using table for input purpose. so in component controller , where i create the element for claimitem node like this,

DATA:

NODE_CLAIM TYPE REF TO IF_WD_CONTEXT_NODE,

NODE_CLAIMITEM TYPE REF TO IF_WD_CONTEXT_NODE,

ELEM_CLAIMITEM TYPE REF TO IF_WD_CONTEXT_ELEMENT,

STRU_CLAIMITEM TYPE IF_COMPONENTCONTROLLER=>ELEMENT_CLAIMITEM .

NODE_CLAIM = WD_CONTEXT->GET_CHILD_NODE( NAME = IF_COMPONENTCONTROLLER=>WDCTX_CLAIM ).

CALL METHOD NODE_CLAIM->CREATE_ELEMENT

RECEIVING

ELEMENT = ELEM_CLAIMITEM.

now if i want to add this element to node claimitem how its possible?

because if i execute application i am getting table in noneditable form..

Thanks,

Hi Saurin,

have you tried to use the BIND_ELEMENT function?

NODE_CLAIM->BIND_ELEMENT(
     new_item = ELEM_CLAIMITEM
     set_initial_elements abap_false ).

Please let me know if this solves your issue?

hi steffen,

as u asked to use Method BIND_ELEMENT,but after creating element for node how can i bind it using this method.

Because this method carrying 1 RETURNIG parameter ELEMENT which type ref to IF_WD_CONTEXT_ELEMENT.and it is not optional.

please let me know how it should work?

Thanks,

Hello Saurin,

This method (BIND_ELEMENT) does indeed return back a reference of type IF_WD_CONTEXT_ELEMENT. You don't have to worry about the value that it returns back to you. The system just returns the reference back so that you can save & use it elsewhere in your program. If you don't need the reference you can omit saving it into some variable & just pass the desired input parameters to the method. So the basic syntax would be something like:

node_flights->bind_element( new_item = first_flight_elem

set_initial_elements = abap_false ).

where:

firs_flight_elem is TYPE REF TO IF_WD_CONTEXTELEMENT

node_flights is TYPE REF TO IF_WD_CONTEXT_NODE

HI UDAY,

thanks to reply me.

What my aim is, i want my table editable for user input with dropdown list in one field, and second field in table with date navaigator.

as i found, what i did, in component controller init method , i initialiaze node and than create element and bind it to claim node. than i created claimitem node thorugh get_child_node method and create element of that and bind it to claimitem node.

no errors.

but when i test application i dont find any rows in output.....
