Different display types in same column

Question

Hi All,
I though I was being clever, but maybe not...
I have a query which generates a column. I want the column to show a select list from query when the user has update permission for the row, otherwise I want to show the value of the column only.
The code for the column is something like this:
select
case when mycolumn='myval'
then apex_item.select_list_from_query('blah, blah')
else
mycolumn
end multitype_column
This displays the data fine - when the data is editable a select list is displayed, otherwise just the value of the data is displayed. The Tabular Form Element of the Column Attribute for this column is 'Standard Report Column'.
My problem is this:
If the first row of the report doesN'T return a select_list for 'mycolumn', I can't get a return value (the index for the select list (where it exists) is F22) from any of the rows which do appear as select lists.
If however the first row is a select list, i can interrogate apex_application.g_f22(i) and retrieve a value for all rows (again where the select_list exists).
So - firstly is this a correct interpretation? Secondly - any fixes?
Thanks very much
Toby

Thanks for replying.
Here is the pertinent code. g_04 represents the database field I examine in order to determine whether the select_list_from_query or a straight report value is rendered. I'm asserting that if the first row of the report has '0' in g_04 then I can see all the values in g_f22 for the page. If the first row g_04 is not '0', I can't access g_f22 for any row (even when I can see values in Firefox->Tools->PageInfo->Forms)
