This is not working
The form builder throws an error

what could be the reason

Answer 1

Code written in When-Mouse-click
for item :boo_toolblk.nbt_nxtscr which contains the form id
DECLARE
p_name_id PARAMLIST;
lv_param_name VARCHAR2(8):= :boo_toolblk.nbt_nxtscr;
lf_next_form_id FORMMODULE;
BEGIN
Clear_Item;
/*Create a parameter list named 'TEMPLT_PARAM'. First
** make sure the list does not already exist, then
** attempt to create a new list*/
IF not Id_Null(Get_Parameter_List('TEMPLT_PARAM'))/*Returns a BOOLEAN value if the object ID is available*/
THEN Destroy_Parameter_List('TEMPLT_PARAM');
END IF;
p_name_id:= Create_Parameter_List('TEMPLT_PARAM');
/*Add a value parameter to an existing Parameter
** List */
Add_Parameter(p_name_id,'templt_nxtscr',TEXT_PARAMETER,lv_param_name);
Go_Block(Get_Form_Property(:system.current_form,FIRST_NAVIGATION_BLOCK));
lf_next_form_id := FIND_FORM(lv_param_name);
:PARAMETER.next_form := lv_param_name;
IF lf_next_form_id.id is not null
THEN
Close_form(lf_next_form_id);
END IF;
Add_parameter(p_name_id,'previous_form',TEXT_PARAMETER,:SYSTEM.CURRENT_FORM);
/* opens another form*/
Open_Form(lv_param_name,ACTIVATE,NO_SESSION,SHARE_LIBRARY_DATA,p_name_id);
EXCEPTION
