How to detect if loading the page from start or back?

My Widget has 3 pages, sailing in the following order:
Page 1-> page 2-> page 3

Loading page 1, I make a web service call to retrieve a json object that I record in a file on the device.
Page 2 and page 3 read the file to view its data.

There are 2 other how to get to page 1:
(1) starting of widget
2) press return on page 2
 
For 1), I want to retrieve the json web service
For 2), I want to retrieve the json in the file (no web service calls)

How can I detect if page1 loads from 1) or (2)?

I found a solution.

Use the blackberry.system.event.onHardwareKey event, I can intercept the previous page 2 key, set the page1 location.href + value of query string indicating that I'm back from page 2.

  • How to assign a value to a control to display after loading the page?

    I use JDeveloper 10.1.3.3 using ADF.

    How can I run a support bean method to populate a control immediately after loading the page. My intention is to populate a control hidden with the session id. The code that I would run is something like this:

    FacesContext ctx = FacesContext.getCurrentInstance ();
    ExternalContext ectx = ctx.getExternalContext ();
    HttpSession mySession = ectx.getSession (false) (HttpSession);
    String sessionId = mySession.getId ();

    Where would I put this code?

    Thank you

    John

    Hi John,.

    create a method called getSessionId returning a string in your bean support.

        public String getSessionId(){
    
            FacesContext ctx = FacesContext.getCurrentInstance();
            ExternalContext ectx = ctx.getExternalContext();
            HttpSession session = (HttpSession) ectx.getSession(false);
            return session.getId(); 
    
        }
    

    then in your page you can use the link editor to call the method and display its value.

  • Generic procedure to load the data from the source to the table target

    Hi all

    I want to create a generic procedure to load data of X number of the source table to X number of the target table.

    such as:

    Source1-> Target1

    Source2-> Target2

    -> Target3 Source3

    Each target table has the same structure as the source table.

    The indexes are same as well. Constraint are not predefined in the source or target tables.there is no involved in loading the data from the business logic.

    It would simply add.

    This procedure will be scheduled during off hours and probably only once in a month.

    I created a procedure that does this, and not like:

    (1) make a contribution to the procedure as Source and target table.

    (2) find the index in the target table.

    (3) get the metadata of the target table indexes and pick up.

    (4) delete the index above.

    (5) load the data from the source to the target (Append).

    (6) Re-create the indexes on the target table by using the collection of meta data.

    (7) delete the records in the source table.

    sample proc as: (logging of errors is missing)

    CREATE or REPLACE PROCEDURE PP_LOAD_SOURCE_TARGET (p_source_table IN VARCHAR2,

    p_target_table IN VARCHAR2)

    IS

    V_varchar_tbl. ARRAY TYPE IS VARCHAR2 (32);

    l_varchar_tbl v_varchar_tbl;

    TYPE v_clob_tbl_ind IS TABLE OF VARCHAR2 (32767) INDEX OF PLS_INTEGER;

    l_clob_tbl_ind v_clob_tbl_ind;

    g_owner CONSTANT VARCHAR2 (10): = 'STG '.

    CONSTANT VARCHAR2 G_OBJECT (6): = 'INDEX ';

    BEGIN

    SELECT DISTINCT INDEX_NAME BULK COLLECT

    IN l_varchar_tbl

    OF ALL_INDEXES

    WHERE table_name = p_target_table

    AND the OWNER = g_owner;

    FOR k IN l_varchar_tbl. FIRST... l_varchar_tbl. LAST LOOP

    SELECT DBMS_METADATA. GET_DDL (g_object,

    l_varchar_tbl (k),

    g_owner)

    IN l_clob_tbl_ind (k)

    FROM DUAL;

    END LOOP;

    RUN IMMEDIATELY "DROP INDEX ' |" l_varchar_tbl (i);

    DBMS_OUTPUT. PUT_LINE (' INDEXED DROPED AS :'|| l_varchar_tbl (i));

    END LOOP;

    RUN IMMEDIATELY ' INSERT / * + APPEND * / INTO ' | p_target_table |

    ' SELECT * FROM ' | '. p_source_table;

    COMMIT;

    FOR s IN l_clob_tbl_ind. FIRST... l_clob_tbl_ind LAST LOOP.

    EXECUTE IMMEDIATE l_clob_tbl_ind (s);

    END LOOP;

    RUN IMMEDIATELY 'TRUNCATE TABLE ' | p_source_table;

    END PP_LOAD_SOURCE_TARGET;

    I want to know:

    Hi 888837,

    Be a little more patient! He is a volunteer help forum where everyone also has a day job. Keep in mind that we probably don't sit in the same time zone and have different work schedules. If you need fast response time, then you should get in contact with the Support of Oracle.

    That said, I had a look at your example. The only error, why it did not work was because you used two different date formats. Used for the switch of date dd/mm/yyyy and to the TO_DATE in the SQL statement, you use mm/dd/yyyy. Now I've changed two masks of DD/month/yyyy format to make it more transparent month. If I now enter on 2 February 2008 and leave the graphic field is getting updated with the expected data.
