How to set value for a node binded to the BOL

Hi,

I have added a new search help in component BT116QH_SRVQ for node 'ZCAMPID' attribute - 'CAMPAIGN_ID'.

I facing values setting the value in this attribute after fetching the value from the search help screen.

This node has the attribute base_entity_name as 'BTOrder'.

if i use

me->typed_context->zcampid->collection_wrapper->get_current( ).

It says that zcampid does not exist.

This node is not available in the comp. controller and hence not able to access throught the comp,controller.

I think i will have to get the current from the BASE_ENTITY_NAME, but i don't know how?

Can you please help me set value to the node 'zcampid'.

Thanks in advance.

Regards

Shanthi.
