Create element in node

[Former Member]

Hi experts,

I need to create new dynamic element in exist node.

This is my coding:

DATA lo_nd_conti_display_table TYPE REF TO if_wd_context_node.

DATA lo_el_table TYPE REF TO if_wd_context_element.

lo_nd_conti_display_table = wd_context->get_child_node( name = wd_this->wdctx_item_basic_data ).

lo_el_table = lo_nd_conti_display_table->get_element( ).

lo_el_table = lo_nd_conti_display_table->create_element( ).

lo_el_table->set_attribute( name = 'ZZ_PROD_TEXT' value = '1' ).

But I have dump at last expression

UNCAUGHT_EXCEPTION

Could not find attribute ZZ_PROD_TEXT

Method: IF_WD_CONTEXT_NODE_INFO~GET_ATTRIBUTE of program CL_WDR_CONTEXT_NODE_INFO======CP

Does this node item_basic_data has the attribute ZZ_PROD_TEXT ?

Hi Baskaran,

Node item_basic_data doesn't has the attribute ZZ_PROD_TEXT . but I want to create it dinamically.

In that case you coding is not correct.

lo_el_table->set_attribute( name = 'ZZ_PROD_TEXT' value = '1' ).

You need to get the node info and use add attribute method like below.

For Dynamically creating Attribute

DATA : 
     rootnode_info TYPE REF TO if_wd_context_node_info,
     dyn_node_info TYPE REF TO if_wd_context_node_info,
     dyn_node TYPE REF TO if_wd_context_node,
     dyn_attr_info TYPE wdr_context_attribute_info.

dyn_attr_info-name = 'ZZ_PROD_TEXT'. 
dyn_attr_info-DEFAULT_VALUE = '1'. 
dyn_attr_info-type_name = 'PROD_NAME' . Data Element(CHAR20) ( Type Of Attribute )

rootnode_info = wd_context->get_node_info( ).
CALL METHOD rootnode_info->add_attribute
EXPORTING
attribute_info = dyn_attr_info.

Hi,

try using that code in the WDDOMODIFYVIEW method of the view in which you want to create the nodes dynamically.

Also if you want that node to be created/inserted into the view when it is displayed for the first time during runtime you can

insert the appropriate code into the WDDOINIT method of that view.

Is ths attribute already defined on the node?

I think not.

First you will have to define the all the attributes you need

Then you create a new element

Hi.,

This is not the right way to create element dynamically.,

Check this wiki ., [Create UI elements Dynamically in WDA|http://wiki.sdn.sap.com/wiki/display/WDABAP/CreatingUIElementsDynamicallyinAbapWebdynpro+Application]

hope this helps u.,

Thanks & Regards

Hi,
