wdctx_node unknown

[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....

First of all Kiran Check the following,

1) Where u have created your node? In Component controller or in View?

2) If you have created the node in Component controller, then you need to define the mapping of the Component controller context node to view context.

3) Check your Node name and get this node using Code wizard (Ctrl+f7).

hi kiran

just check your mapping part...........

and double click on if_input_view n check and then try to analyse the problem...

and also

Just make sure that the spelling of the node name is correct used in the code..

Go to the Context tab and check if it is spelt properly.

thanks

Hi Kiran,

Can you please witre the problem you was facing, as this will be helpful for others in future with the same type of error.

just drag the context node which u hv created in ur component controller to the view , so that the context node NODE_VBAK is accessibe across ur view , thn using code wizard(control+f7) ; read the context node .. the code will be auto generated

[Former Member]

WDCTX_NODE_VBAK is actually the reference of the context node NODE_VBAK. Check in the context that you have created a node with the same name. Nay be some spell mistake is there.

Hope it helps you.

Hello Kiran . pl check the following points.

1) have u created the Node by usind wizard?

2) have u read that NOde in the method ONACTIONACTION_FIND.. if not use code wizard and read the node Properly.

comign to Debugging .. put a Break point in WDDOINT of Main view And run the application ..

Hope it will help you.
