add_attribute, set_attribute

[Former Member]

Hi

I need your great knowledge.

I have an alv table with a context node created at design time (i want to change this later on maybe...)

now i add an attribute with add_attribute

no problem

i set the value of the attribute

no problem (?)

for checking i get the value of the attribute again.

no problem

but i don't see the value in the alv tree...

or in another way

how can i fill the values of the added attribute with code.

Is there anything spezial i need to to do, for non static attributes?

...
          co_el->get_attribute( exporting name = 'SWITCHF' importing value = value ).
          co_el->set_attribute( name = 'SWITCHF' value = 'X' ).
          co_el->get_attribute( exporting name = 'SWITCHF' importing value = value ).

          node_data->set_attribute( INDEX = 1 VALUE = 'X' name = 'SWITCHF' ).
...

...
  data attr type WDR_CONTEXT_ATTRIBUTE_INFO.
  attr-NAME = 'SWITCHF'.
  attr-DEFAULT_VALUE = ' '.
  attr-TYPE_NAME = 'WDY_BOOLEAN'.
*  attr-IS_STATIC = 'X'.
*  attr-NODE_INFO = node_info.
  node_info->ADD_ATTRIBUTE( attr ).
...

(((is there a way to debug the actual viewed table of the alv?)))

To fill data in an ALV table, you will have to fill your data in an internal table and bind it to your node.

l_node->bind_table( internal table name ).

Good point.

But i don't have problems with getting data in the table generally. The attributes i have created at disign time are filled with values.

my solution at the moment is to create the whole conntext by hand

something like this maybe if somebody else has a similiar problem. I only copy part of my solution to give a hint:

...
  data comp_tab type abap_component_tab.
  data comp type abap_componentdescr.
...
loop at lt_cust into lw_cust. "this could be the ddict info from the original stuct. in my case this is a customizing table to change the order of my columns, because i don't like to (or the user) to change the context node...)
      data tem type string.
      concatenate dso_tabname '-' lw_cust-iobjnm into tem.
      comp-name = lw_cust-iobjnm.
      comp-type ?= CL_ABAP_DATADESCR=>DESCRIBE_BY_NAME( tem ).
      append comp to comp_tab.
endoop.

...
    comp-name       = 'INDEX'.
    comp-type ?= CL_ABAP_DATADESCR=>DESCRIBE_BY_NAME( 'I' ).
    append comp to comp_tab.

    comp-name       = 'CHANGEABLE'.
    comp-type ?= CL_ABAP_DATADESCR=>DESCRIBE_BY_NAME( 'WDY_BOOLEAN' ).
    append comp to comp_tab.

   data rtti TYPE REF TO CL_ABAP_STRUCTDESCR.
   rtti ?= CL_ABAP_STRUCTDESCR=>CREATE( P_COMPONENTS = comp_tab ).

    node_info->add_new_child_node(
            name                   = 'DATA2'
            STATIC_ELEMENT_RTTI = rtti ).
...

while i am writing this, there are so many questions, but this should be of use for somebody else even

may i get points for this;-)
