Dump issue for binding context node on Web UI

[Former Member]

Hi Colleague,

I create a binding for the context node as below for getting customizing values for a dropdown list, but there is a dump issue occured when clicking on Save button, which runtime error is 'RAISE_EVENT_NESTING_LIMIT'. If I remove this binding, no dump issue and can save activity successfully. Could you also explain more about binding relationship among different context nodes on Web UI?

Kind Regards

Andie

Hi Srinivas,

Do we have to use customer controller to bind context node? I created several context nodes using wizard as below, I try to only bind BTAdminH context node to customer controller, but one field using one attribute under BTSubject context cannot get dropdown list values from customizing setting. If I bind BTSubject context node to BTAdminH, the dropdown list values can be gotten, but I got dump issue as mentioned above.

I also try to disable enhancements via go to transactoin SU3, then set the parameter to WCF_IGNORE_ENHANCEMT and value as 'A', after doing this, the another dump issue occurs when choosing default business role.

BTAdminH     BTAdminH   0

BTActivityH    BTActivityH      BTAdminH     BTHeaderActivityExt

BTDatesSet   BTDatesSet      BTAdminH     BTHeaderDatesSet

BTDate          BTDate             BTDatesSet    BTDatesAllCust_ACTIVITY

BTBOSSet     BTBOSSet       BTAdminH      BTHeaderBOSSet

BTSubjectSet BTSubjectSet  BTBOSSet      BTSubjectSet_A

BTSubject       BTSubject       BTSubjectSet  BTSubjectSingle

Kind Regards

Hi Andie,

You have to create BTADMINH context node then you have to create BTSUBJECTSET and BTSUBJECT context nodes.

You created context node and relations are correct. You have to bind BTADMINH to BTADMIH context node only. If you are not getting drop down value try to debugg what is the issue in method GET_V of the attribute.

Hi Deepika,

If I only bind BTADMINH to BTADMINH context code, the variant lr_current as below cannot get any value in method GET_V of the attribute.

lr_current ?= me->collection_wrapper->get_current( ).

Kind Regards

Hi Andie,

You need to have proper connection between BTAdminH and BTSubject context nodes, otherwise system will not give you updated collection.

You have to create BTSUBJECT context node as child node for BTSUBJECTSET and BTSUBJECTSET should have get the updated collection from BTAdminH in ON_NEW_FOCUS method in BTSubjectSet context node.

You have already created both BTSubjectset and BTSubject context nodes right, did you mention any relationship between these node while creating the context nodes.

Just do the below steps and check whether the collection is getting filled in BTSubject context node,

Go to CTXT class Create_BTSUBJECT add the below code

* initial setting for depandant model node

     coll_wrapper =

       BTADMINH->get_collection_wrapper( ).

     TRY.

         entity ?= coll_wrapper->get_current( ).

       CATCH cx_sy_move_cast_error.

     ENDTRY.

     IF entity IS BOUND.

       BTSUBJECT->on_new_focus(

                    focus_bo = entity ).

     ENDIF.

And then go to BTSUBJECT context node class and add on_new_focus method in CNXX class as shown below screen shot, You can get the below popup by clicking the details view icon

Once you created on new focus method add the code as shown in below

data: lv_collection type ref to if_bol_bo_col,

         lr_entity     type ref to cl_crm_bol_entity,

         lr_entity_dep type ref to cl_crm_bol_entity.

*   get collection of dependent nodes

   lr_entity ?= focus_bo.

   try.

       lr_entity_dep = lr_entity->get_related_entity(

              iv_relation_name = 'BTHeaderBOSSet' ).

     catch cx_crm_genil_model_error.

*       should never happen

       exit.

     catch cx_sy_ref_is_initial.

   endtry.

   lr_entity ?= lr_entity_dep.

   try.

       lr_entity_dep = lr_entity->get_related_entity(

              iv_relation_name = 'BTSubjectSet_A' ).

       if lr_entity_dep is not bound.

         if lr_entity->is_changeable( ) = abap_true.

           try.

               lr_entity_dep = lr_entity->create_related_entity(

                iv_relation_name = 'BTSubjectSet_A' ).

             catch cx_crm_genil_model_error cx_crm_genil_duplicate_rel.

*               should never happen

           endtry.

         endif.

       endif.

     catch cx_crm_genil_model_error.

*       should never happen

       exit.

     catch cx_sy_ref_is_initial.

   endtry.

   lr_entity ?= lr_entity_dep.

   try.

       lr_entity_dep = lr_entity->get_related_entities(

              iv_relation_name = 'BTSubjectSingle' ).

       if lr_entity_dep is not bound.

         if lr_entity->is_changeable( ) = abap_true.

           try.

               lr_entity_dep = lr_entity->create_related_entity(

                iv_relation_name = 'BTSubjectSingle' ).

             catch cx_crm_genil_model_error cx_crm_genil_duplicate_rel.

*               should never happen

           endtry.

           if lr_entity_dep is bound.

             create object lv_collection

               type

                 cl_crm_bol_bo_col.

             lv_collection->add( lr_entity_dep ).

           endif.

         endif.

       else.

         if lr_entity_dep is bound.

           create object lv_collection

             type

               cl_crm_bol_bo_col.

           lv_collection->add( lr_entity_dep ).

         endif.

       endif.

     catch cx_crm_genil_model_error.

*       should never happen

       exit.

     catch cx_sy_ref_is_initial.

   endtry.

   me->collection_wrapper->set_collection( lv_collection ).

Hi Dharmakasi,

I create BTSUBJECT context node as child node for BTSUBJECTSET, it works well now, thanks a lot!

Kind Regards
