Hi,

An idea:

Before clearing variables when showing your tree again, try to call the method FREE on your container and Tree object so they are re-created properly...

E.g:

obj_tree->free( ).

obj_alv->free( ).

obj_cont1->free( ).

obj_cont2->free( ).

and then your CLEAR statement:

CLEAR: obj_tree, obj_alv, obj_cont1, obj_cont2.

Hi,

Of course you need to call the free method only if your objects are bound!

E.g. I would have call your free routine only when the user press BACK from result screen...

This is what i did when 'Execute' button is triggered in PAI.

i am calling form clear.

i have not cleared obj_tree(its commented in code below).if i clear that i am not able to execute the 1st time itself..(the tree does not appear)

FORM CLEAR.

obj_tree->free( ).

obj_alv->free( ).

obj_cont1->free( ).

obj_cont2->free( ).

   CLEAR :IT_NODETAB,

   LT_MARA,

   LT_MARC,

   LT_MARD,

   LT_SALES,

   LT_PLANT,

   LT_INVENT,

   LT_FORMS,

   LT_MAKT,

   LT_MVKE,

   lt_dwerk,

   it_event,

   OBJ_CONT1 ,

*  OBJ_TREE  ,

   OBJ_CONT2 ,

   obj_ALV   ,

*  obj_handle,

FLAG,

   flag_sal,

   TY_TOOLBAR,

   IT_NODE,

   FLAG_node,

   wa_node,

   IT_TOOLBAR.

ENDFORM.

yeah..But my requirement doesn't have back button its a same screen.what to do ??

[Former Member]

That's why I said you should call your free routine when the user gets back to the selection, not when pressing 'EXECUTE'...

Otherwise you can just check if your object is bound before freeing it:

IF obj_tree is BOUND.

     obj_tree->free( ).

"...

ENDIF.

thanks 4 helping..sorry again for one more newbie question..

"call your free routine when the user gets back to the selection" in the sense which selection it is?? were in code?? sorry again for newbie ques

[Former Member]

Oups, I just see that you are using only one screen (no selection screen)...

So you definitely have to check if the objects are bound, freeing and clearing them in your form EXECUTE...

Check this, put a break point in your PBO and ensure your objects are re-created correctly...

Now 1st time when i execute its executing fine.when i click second time its going for DUMP in

OBJ_alv->free( ).

When 'EXECUTE'.
PERFORM CLEAR.
FORM CLEAR.
 IF obj_tree is BOUND.
      obj_tree->free( ).
      clear   OBJ_TREE .
 ENDIF.
 IF OBJ_CONT1 is BOUND.
      OBJ_CONT1->free( ).
      clear   OBJ_CONT1 .
 ENDIF.
 IF OBJ_CONT2 is BOUND.
      OBJ_CONT2->free( ).
      clear   OBJ_CONT2 .
 ENDIF.
   IF OBJ_alv is BOUND.
      OBJ_alv->free( ).
      clear   OBJ_alv .
 ENDIF.
   CLEAR :IT_NODETAB,
   LT_MARA,
   LT_MARC,
   LT_MARD,
   LT_SALES,
   LT_PLANT,
   LT_INVENT,
   LT_FORMS,
   LT_MAKT,
   LT_MVKE,
   lt_dwerk,
   it_event,
   obj_handle,
 FLAG,
   flag_sal,
   TY_TOOLBAR,
   IT_NODE,
   FLAG_node,
   wa_node,
   IT_TOOLBAR.
 ENDFORM.

Issue solved.

Thanks all

Hi,

No you don't have to remove it! Just place it before you free the related container (I guess CONT2)...

Always free children before parents!
