Issue with $FLEX$ and populating dates.

Question

Hello,
I'm creating a custom report for a HR report. I have a requirement to enter a report type, if that report type <> 'DATE' then the parameters to enter dates are to be disabled. I when through the following steps.
Steps:
1. Define controlling parameter, XXRPT_TYPE
2. Define parameter - P_HIDDEN_PARAM. As it's name suggests, this is a hidden parameter, which will not be visible when we submit the conc. program.
Set it's Default Type as "SQL Statement " and
Default value as - "select decode(:$FLEX$.XXRPT_TYPE,'DATE','Y',null) from dual".
3.Define custom valueset, which will used for the date parameters - " Date From" and "Date To".
a) Click on Edit Information and enter forllowing query in Table Name field.
(SELECT (TO_DATE (SYSDATE - 200 + LEVEL, 'DD-MON-RRRR')) date_range FROM DUAL CONNECT BY LEVEL <= 1000)temp_tab
I am using "CONNECT BY LEVEL" concept to produce dates with the range of 1000 days.
You can modify 1000 to any other figure as per your requirement.
b) Set Value Name as date_range, which is nothing but the alias name in the query above.
c) I Entered following WHERE clause in Where/Order By field.
WHERE :$FLEX$.AMS_SRS_CHAR50='DATE RANGE'
When I run the concurrent program, the date field will disable if the report type will is on something other than Date Range, however when the report type is date range, I get an error (No Entries found for List of Values) If I comment the where clause then the date are displayed, but the disabling doesn't work. Does anyone have any ideas for me?
