Rollback in Master-Detail form - SOLVED

Question

Hellou.
I have 2 blocks Mater-Detail relation. I execute query and make some changes in Items from block 1 and some changes in items in block 2.There are althoug some POSTs. I have Button "Change Back" and i need to use this button to rollback all changes i have made (All post will be rollbacked). But it always rollback me only DETAIL block items, but MASTER block items didn't rollback.
I use Forms_ddl('rollback')
Althoug I change Session_mode to OFF and perform FULL rollback. But always the same. Master block NO ROLLBACK.
Some ideas???

I want rollback and continue in query.I guess I don't understand what you are trying to do. Do you simply want to be at the same record when a rollback is issued? If so, this can still be accomplished using CLEAR_FORM() built-in. You simply need to capture the pertinent data so you can return to this record after the Form has been re-queried. For example, the user in on record number 75 when they decide they need to rollback the changes. In your Button trigger, you will need to capture that a rollback was performed and store the current record in a parameter or global variable. When the form is re-queried, check to see if a rollback was done and if so use the GO_BLOCK(), GO_ITEM(), and GO_RECORD() built-ins to return the user to the record they were on when they clicked on the Rollback button.
For Example:
When-Button-Pressed trigger
BEGIN
   /**I prefer to use Forms Parameters to capture Forms unique global variables because
      these values only apply to the current form and shouldn't be visible to other Forms
      in the same session. **/
   :parameter.rollback_issued := 'Y';
   :parameter.current_block := :system.current_block;
   :parameter.current_item := :system.current_item;
   :parameter.current_record := :system.current_record;
   /**If you modified the Data Block's Default Where clause you will want to capture this
       information also. **/
   :parameter.curr_blk_def_where := get_block_property(:system.current_block,DEFAULT_WHERE);
   CLEAR_FORM(NO_COMMIT,FULL_ROLLBACK);
END;Now, in your When-New-Form-Instance or When-New-Block-Instance trigger do something like:
BEGIN
   IF (:parameter.rollback_issued = 'Y') THEN
      :parameter.rollback_issued := 'N';
      set_block_property(:parameter.current_block,DEFAULT_WHERE,:parameter.curr_blk_def_where);
      GO_BLOCK(:parameter.current_block);
      EXECUTE_QUERY;
      GO_ITEM(:parameter.current_item);
      GO_RECORD(:parameter.current_record);
   ELSE
      /** Do what you would normally do here.  **/
   END IF;
END;If this is not what you are trying to achieve, please post what you are trying to achieve and why the CLEAR_FORM() method wont work and we'll see if we can help you find a way to achieve what you are trying to do.
Hope this helps.
