Write Back only works when a columns is updated.

Question

Hi,
We have Write Back enabled in one of our request.  The request is simple, we just have 3 columns (AV_MONTH, a hidden column with the User() name function, and APPR1_NAME). We display only current month (then only 1 row).  The user does not update any value in any column.  He just click on the button and the xml executes the statement below to update the appr1_name column with the User() value for the corresponding month.
xml
UPDATE MONTHLY_APPROVAL SET APPR1_STATUS=1 ,APPR1_NAME='@{c1}' WHERE AV_MONTH=to_date('@{c0}','yyyy-mm-dd hh24:mi:ss')
This has been working fine in in BI 10.1.3.4 (Build 080726.1900) but now we're migrating this to 10.1.3.4.1 (Build 100319.0954) and it has stopped working.
The xml is executing the update statement only if we update the hidden column.
For example, In My request I see
Feb-2014 | John. Doe | <blank>
The first column is the month in the table.
Second column is the function User().  This is the name of the user logged in that we're using to update the username(APPR1_name) in the table
and the last column is black since we have not updated the user name in the table yet.
If I click the button the update statement in the xml is not executed.
But if I change John.Doe by John.Do then the xml detects the column was updated and then it executes the update statement.
The issue is that the user is not supposed to update any column.
Please any help will be appreciated.  Also, is there any log file for Write Back?
Thanks.

Is it an Apple Bluetooth keyboard? You've no doubt checked the batteries are OK, although they shouldn't have gone flat in a few days.
You could try re-pairing it to see if it sticks, and you may want to make it a favourite, which helped when my Magic Mouse kept losing the BT connection.
Using the wired keyboard delete the BT keyboard from BT Preferences. Pair it again and when it's (hopefully) connected from the BT prefs window bottom left, click on the 'cog' and select 'Show more options'. You should then get the opportunity to make it a favourite. Disconnect the wired keyboard and fingers-crossed.
