Context Change Log not working if I delete the Element from Context Node

[Former Member]

Hi ,

Step1 :- I have enabled the context change log .

Step2 :- I am deleting the element from Context Node ..

(Node had only one element before deletion so now it does not have any element.)

Step3 :- Context Change log does not return any list for change log .

If someone can guide me here it would be great help to me.

Hi,

WD ocntext change log does not reflect the programmatic changes. WD context change log only log the changes which are manually done by user.

for ex: value entered in input field.

Deleting element from context node is programmtic change. it will not be reflected in WD context change log.

Try out with WD_CONTEXT_CHANGE_SERVICES

Thanks a lot for quick response.

But can you please tell me how to use this WD_CONTEXT_CHANGE_SERVICES to get the

expected behaviour ?

Hi,

You have to register your node for subscription.

CLASS = CL_WD_CONTEXT_SERVICES

data mo_context_services type ref to CL_WD_CONTEXT_SERVICES.

In this case you have to register your node to keep track of change log.

IF wd_this->mo_context_services IS NOT BOUND.

CREATE OBJECT wd_this->mo_context_services.

ENDIF.

DATA:

lt_subscription TYPE cl_wd_context_services=>subscription_list,

ls_subscription TYPE cl_wd_context_services=>subscription_element,

ls_subscription-controller = lo_ndi_header->get_controller( ).

ls_subscription-node_name = 'HEADER'.

APPEND ls_subscription TO lt_subscription.

wd_this->mo_context_services->subscribe_to_node_changes(

subscriptions = lt_subscription ).

wd_this->mo_context_services->activate_subscriptions( ).

use method GET_CHANGE_LIST( CL_WD_CONTEXT_SERVICES) method to get the change log from context services.

Check for the change kind = COLLECTION_CHANGED. it will show the change in the number of elements of node.

Thanks,

Rahul
