Item types can be associated with attributes. The default value for such an attribute can be set through PL/SQL code as illustrated in the Portal User's Guide :

" Adding Attributes to an Item Type
7. When you have added the attributes, you can change their display properties if necessary:

To set the default value of a custom Project ID attribute to the current project to which the current user is assigned, you would first need a function that returns the ID of the project. The function might be something like the following (assuming that a user is assigned to only one project on any specified date):

create function GET_CURRENT_PROJECT return VARCHAR2 as
   project_id VARCHAR2 (30);
   select into project_id from project_asignments pa
   where SYSDATE between pa.start and pa.end -- selects current assignment
   and pa.assignee = WWCTX_API.GET_USER; -- gets name of current user
   return project_id;
 end;  "


For an item type where the attribute's default value is generated from PL/SQL, an error occurs when adding an item based on this item type to an item region on a Portal page :

  1. ORA-01840 when the return value of the PL/SQL code is only 1 character in length and has a numerical value, e.g. 1

    internal error (WWC-00006)
    Unexpected error - ORA-01840: input value not long enough for date format (WWC-35000)

  2. ORA-01861 when the return value of the PL/SQL code is more than one character in length.

    internal error (WWC-00006)
    Unexpected error - ORA-01861: literal does not match format string (WWC-35000)

Steps To Reproduce:

  1. Create Page group PG_Test111.
  2. Create attribute att_test based text.
  3. Create item type : item_type_test.
  4. Edit the new Item and Click on attributes tab.
  5. Select att_test to be on the right on the selected attributes.
  6. Below in the attributes properties, for the new item added: att_test
    - Default value <USER.Procedure>
    - Check boxes: "Required", "Add Wizard", "Edit Wizard"
  7. Click on procedure tab.  Under "Procedure Call Properties":
    Type: PLSQL
    Procedure Call: <USER.Procedure>
    Link Text: <USER.Procedure>
  8. Click Apply, OK.
  9. Go to PG_Test111 root page
  10. Add an item.
  11. Select "item_type_test" type
  12. Click next and the item wizard is opened and at the bottom of the page:
