Using APEX_ITEM.MULTI_ROW_UPDATE along with APEX_ITEM.CHECKBOX

Question

Hi,
I am stuck working with APEX_ITEM.MULTI_ROW_UPDATE process for the past 2 days.
I don't see any working examples in forum as well to update APEX_ITEM.CHECKBOX values using the APEX_ITEM.MULTI_ROW_UPDATE process.
My updateable query is as below :
select APEX_ITEM.HIDDEN(1,INST_ID) ||
       APEX_ITEM.TEXT(2,INST_NME,20,200) AS INST_NME,
       APEX_ITEM.TEXT(3,INST_CTY_TXT,10,50) AS INST_CTY_TXT,
       APEX_ITEM.SELECT_LIST_FROM_LOV(4,ST_CDE,'STATES_LOV',NULL,'YES','ZZ','~ Select ~') AS ST_CDE,
       APEX_ITEM.MD5_CHECKSUM( INST_NME,
                               INST_CTY_TXT,
                               ST_CDE,
                               LGE_IND
                    ) || APEX_ITEM.CHECKBOX(5,LGE_IND,NULL,-1) AS LGE_IND
from  TESTNote: I am using -1 for checked value of checkbox.
My update process is
  BEGIN
    APEX_ITEM.MULTI_ROW_UPDATE('#OWNER#:TEST:INST_ID,1:,|INST_NME,2:INST_CTY_TXT,3:ST_CDE,4:LGE_IND,5');
  END;Now when I update any field and Save the changes I get the error below :
  ORA-20001: Error in MRU: row= 1, ORA-01403: no data found, update If I use textbox instead of checkbox and write the code as below it works perfect.
select APEX_ITEM.HIDDEN(1,INST_ID) ||
       APEX_ITEM.TEXT(2,INST_NME,20,200) AS INST_NME,
       APEX_ITEM.TEXT(3,INST_CTY_TXT,10,50) AS INST_CTY_TXT,
       APEX_ITEM.SELECT_LIST_FROM_LOV(4,ST_CDE,'STATES_LOV',NULL,'YES','ZZ','~ Select ~') AS ST_CDE,
       APEX_ITEM.MD5_CHECKSUM( INST_NME,
                               INST_CTY_TXT,
                               ST_CDE,
                               LGE_IND
                    ) || APEX_ITEM.TEXT(5,LGE_IND,5,10) AS LGE_IND
from  TEST;
  BEGIN
    APEX_ITEM.MULTI_ROW_UPDATE('#OWNER#:TEST:INST_ID,1:,|INST_NME,2:INST_CTY_TXT,3:ST_CDE,4:LGE_IND,5');
  END;If anyone see what is wrong that I am doing please help me out here.
Your help is greatly appreciated.
Thanks,
Raj.

Hi,
You should concatenate your HIDDEN item(s) to the front of the next displayed item - that way you do not get a column in the tabular form that you have to hide (hiding the column could have the effect of stopping the item from being submitted with the page)
Secondly, all the fields should be based on actual column names so that the MD5_CHECKSUM that reference these.
DUAL doesn't provide column names directly but you may be able to do something like:
SELECT
APEX_ITEM.HIDDEN(1, ID) || APEX_ITEM.TEXT(2, PRODUCT_NAME, 60, 60) product_name,
APEX_ITEM.SELECT_LIST_FROM_LOV(3,CATEGORY,'CATEGORY',NULL,'YES',NULL,'-Select Category-',null,null,'NO') CATEGORY,
APEX_ITEM.MD5_CHECKSUM(PRODUCT_NAME,CATEGORY)
FROM (SELECT NULL ID, NULL PRODUCT_NAME, NULL CATEGORY FROM DUAL)Alternatively, you could create an empty row from the actual table:
SELECT
APEX_ITEM.HIDDEN(1, ID) || APEX_ITEM.TEXT(2, PRODUCT_NAME, 60, 60) product_name,
APEX_ITEM.SELECT_LIST_FROM_LOV(3,CATEGORY,'CATEGORY',NULL,'YES',NULL,'-Select Category-',null,null,'NO') CATEGORY,
APEX_ITEM.MD5_CHECKSUM(PRODUCT_NAME,CATEGORY)
FROM (SELECT NULL ID, NULL PRODUCT_NAME, NULL CATEGORY FROM EBA_ASSET_ASSETS WHERE ROWNUM = 1)Then Scott's code should work:
BEGIN
APEX_ITEM.MULTI_ROW_UPDATE('#OWNER#:EBA_ASSET_ASSETS:ID,1:|ASSET_NAME,2:CATEGORY_ID,3');
END;Note that you have to include the : before the | as this function assumes that there are two primary keys - as the table only has one, the second one is empty, but must be included.
