View Fields greyed out

[Former Member]

Hello,

Under the component ICCMP_BT_INR, I have called a custom Component ZIBCOMP,which has functional location details.

My custow view under the custom component ZIBCOMP has 3 fields and all of then are greyed out.

For ex:

In usual UI screens we have

Field Label : _______________ (Place holder for entering the value)

In my view the place holder after field label is not visible:

Field Label : NOT VISIBLE (Place holder for entering the value)

Please suggest,if am missing anything in designing the view.

One more thing is my custom component is integrated into the Custom View set in the standard Component.Is something wrong

with the Viewset design?

Hi,

I think the basic problem is with the context node entity which you are using to display the 3 fields,

The basic rule is that if your entity is properly created in the create context node methods, then

the field would be editable.(created and in edit mode)

lets assume that you are displaying the 3 fields from XXX context node in the view and XXX context node

has a standard base_entity and it is related to some other standard root entity with the relation which u see in the

bol_model_browser. So in the create_xxx method, after the standard code creates the model and assigns it

to you context node, you should call another method like on_new_focus(check any standard code to see the method definition).

this method resides in the xxx context class and call the method like xxx->on_new_focus( lcl_entity ) from the create_xxx method.

the lcl_entity should be the parent of that xxx entity. inside the on_new_focus add the code to create a related entity

of the parent if there is no entity created. (see the bol_model_browser to check the relation between ur xxx and parent node.)

let me know it worked or not..

Hello Asen,

Its quiet confusing for me .Let me provide me the details:

Stanadard Component : SRQM_INCIDENT_H

Custom Component created : ZICCMP_IBCOMP ,View : ZIbase

Context Node: BTREFOBJ

The view in the custom component has the fields Ibase,Component and Prodcut ID.These fields values will be entered by the user (should be in input mode,they are not as of know). One question here..do ihave to use a Model node or Value node here?

Code under CREATE_BTREFOBJ:

DATA lr_entity TYPE REF TO cl_crm_bol_entity.
* in case that the focus_bo (predecessor) exists and is changeable,
* then create a collection for the data of the view. otherwise remove
* the collection which leads to read-only fields.
  IF focus_bo IS BOUND.
    lr_entity ?= focus_bo.
    IF lr_entity->is_changeable( ) EQ abap_true.
      me->clear_collection( ).
    ELSE.
* Allow user to create follow-up even the service ticket is set to complete
*      me->collection_wrapper->clear_collection( ).
      me->clear_collection( ).
    ENDIF.
  ELSE.
    me->collection_wrapper->clear_collection( ).
 ENDIF.

Please suggest the necessary modifications.

the code inside CREATE_BTREFOBJ should be like this..

• assumption: this context node is a model node. whether it is value node/model node, it depends on the fields u will use. if all the fields which you want to display is available in the standard entity which has a relation with the header entity then use model node. other wise use value node,, but then you have to code to save the data.

DATA:

model TYPE REF TO if_bsp_model,

coll_wrapper TYPE REF TO cl_bsp_wd_collection_wrapper,

entity TYPE REF TO cl_crm_bol_entity, "#EC *

entity_col TYPE REF TO if_bol_entity_col. "#EC *

model = owner->create_model(

class_name = 'CL_SRQM_H_BTREFOBJ_CN' " replace with the class it has already created

model_id = 'BTREFOBJ' ). "Check the case

CLEAR model.

• initial setting for depandant model node

coll_wrapper = btadminh->get_collection_wrapper( ). " if parent is other than btadminh, use that here instead of btadminh

TRY.

entity ?= coll_wrapper->get_current( ).

CATCH cx_sy_move_cast_error.

ENDTRY.

IF entity IS BOUND.

BTREFOBJ->on_new_focus( focus_bo = entity ).

ENDIF.

the on_new_focus method should have code like this. Please see any on_new_focus method, so that u create it correctly. It is not a normal method, it is event handler method. click the button beside the documentation button to set the properties for event handling.

DATA: lv_collection TYPE REF TO if_bol_bo_col,

entity TYPE REF TO cl_crm_bol_entity.

• get collection of dependent nodes

entity ?= focus_bo.

TRY.

lv_collection = entity->get_related_entities(

iv_relation_name = 'BTREFOBJ_rel' )." add the correct relation

IF lv_collection IS NOT BOUND or lv_collection->size( ) = 0.

IF entity->is_changeable( ) = ABAP_TRUE.

TRY.

entity = entity->create_related_entity(

iv_relation_name = 'BTREFOBJ_rel' ). " add the correct relation

CATCH cx_crm_genil_model_error cx_crm_genil_duplicate_rel.

• should never happen

ENDTRY.

IF entity IS BOUND.

CREATE OBJECT lv_collection TYPE cl_crm_bol_bo_col.

lv_collection->add( entity ).

ENDIF.

ENDIF.

ENDIF.

CATCH cx_crm_genil_model_error.

• should never happen

EXIT.

CATCH cx_sy_ref_is_initial.

ENDTRY.

me->set_collection( lv_collection ).

Hello Asen,

How should i identify Header entity of any entity?

Any specific Tcode?

Hi,

lcl_entity->get_parent(). returns the parent.

lcl_entity->get_root( ). returns root entity

If you need to see the model - then go to GENIL_MODEL_BROWSER. you have to find it there ...

HI Khaya.

I'd think there's something wrong with your view configuration. Could you share your layout page html code?

If it looks like this:

<%@page language="abap" %>
<%@extension name="thtmlb" prefix="thtmlb" %>
<%@extension name="chtmlb" prefix="chtmlb" %>
<%@extension name="bsp" prefix="bsp" %>
<chtmlb:config mode = "RUNTIME"
               xml  = "<%= controller->configuration_descr->get_config_data( ) %>" />

then check your view config from the UI config tool. Try deleting the config, and re-creating it.

Hope it helps.

Hello Sebastine,

I replaced the following code by the code provided by you:

<chtmlb:overviewFormConfig/>

<chtmlb:config mode = "RUNTIME"
               xml  = "<%= controller->configuration_descr->get_config_data( ) %>" />

Then i deleted the configuration and created a new one.After creation of new config am getting the following error:

Cannot display view ZICCMP_IBCOMP/ZIbase of UI Component ZICCMP_IBCOMP

An exception has occurred Exception Class CX_BSP_ELEMENT_EXCEPTION - : No valid source context supplied Method: CL_BSP_ELEMENT=>IF_BSP_ELEMENT~RAISE_ERROR

Source Text Row: 3

The contect node is already available.

Please suggest.

Hello,

I deleted the configuration tab and created it again.Now i can see the reuqired fields in the component,with there place holder

But,the ppalce holders are greyed out i.e the fields ar not input enabled.Though the field's properties in configuration tab say the

field type as INPUT FIELD.

Further anything need to be done at layout code.
