CRM Web UI table sorting field

[phoenixming0912]

Hi all,

I have a question about sorting field.

Basically, there are two types of field, BOL attribute and single value attribute.

I use method "EH_ON_SORT" and "me->collection_wrapper->sort(attribute_name)" to sort, but this only works for BOL attribute. If I passed signle value attribute as parameter, the method would catch an error "CATCH cx_crm_cic_parameter_error."

Does anyone know how to sort by single value attribute?

Yes, the GET_P should have something like this:

METHOD get_p_attr_code.
  CASE iv_property.
    WHEN if_bsp_wd_model_setter_getter=>fp_sortable.
      rv_value = 'FALSE'.
  ENDCASE.
ENDMETHOD.

Also, have you checked the xception in ST22? This should be something really straight forward.

Regards.

Alejandro.

Hi Alejandro,

Method "get_p" is just to display sort option in UI, by default the field is sort enable.

Finally, I got it worked. The problem is that I should set property into collection for a value attribute BEFORE sorting.

Now I do the property setting in DO_PREPARE_OUTPUT.

current->set_property( iv_attr_name = 'ZSORT_FIELD' iv_value = xxx ).

Hi Eric,

The SORT method which is under the Collection_Wrapper reference should be fine for you. Even more, look at the attached screenshot where I am sorting a Value node:

In addition to this, your exception sounds to me as if you would be sending wrong or incomplelte information to the Sort method. Have you checked that alredy?

Regards.

Hi Alejandro,

I also used the event "EH_ON_SORT" to sort, but looks like this method only works for BOL attributes, it doesn't work for single attributes. I passed the single attribute name into sort method and got the "parameter error" exception.

I have debugged and found "GET_P_XXX" of value attribute is executed after event "EH_ON_SORT", so what I am thinking of is to sort in method "DO_PREPARE_OUTPUT".
