wdctx_node unknown error

[Former Member]

Hi all,

I am new to WebDynpro and Every time we create a webdynpro application

we are getting a problem in Action coding part for eg.

• navigate from <CONTEXT> to <NODE_VBAK> via lead selection**

*node_node_vbak = wd_context->get_child_node( name = if_input_view=>wdctx_node_vbak ).*

we are using this code in Action Event and we r getting this error ..

Web Dynpro Comp. / Intf. ZSAMPLE_TEST,Web Dynpro View INPUT_VIEW

Method ONACTIONACTION_FIND

Field "WDCTX_NODE_VBAK" is unknown. It is neither in one of the

specified tables nor defined by a "DATA" statement . . . . . . . . . .

and also how to debug webdynpro application actually we are setting external BREAK-POINT but its not working.

Plz Help....

This is WDA related question, you posted in abap general forum.

node_node_vbak = wd_context->get_child_node( name = if_input_view=>wdctx_node_vbak ).**

should be

node_node_vbak = wd_context->get_child_node( name = wd_this->wdctx_node_vbak ).**

the syntax is wd_this->wdctx_[name of the node]

It is automatically generated by the framework as constant in the if_input_view.
