Query Builder - Where Clause - Could not format error using date comparison

Question

We've come across a bug in the Query Builder, under the Create Where Clause tab, if you select a column of Date type plus one of the comparison operators =, !=, <, >, <=, >=, BETWEEN or NOT BETWEEN it displays an error in the Logging Page:
Level: Severe
Source: o.d.r.queryBuilder.SQLGenerator
Message: Could not format :2010-09-02 16:20:31.0
Then under the Show SQL tab it doesn't display the date(s) you selected, e.g.
WHERE LAST_UPDATE BETWEEN AND
Also the View Results tab does not display any results.
You can still press Apply to add the SQL as is to the editor window and from there you have to manually code in the date parameters.
We're using the latest version of SQL Developer 2.1.1.64.45 Windows 32bit version with JDK

Hi Gordon,
When I add the following lines:
declare @refdt1 date
set @refdt =
/*select 1 from jdt1 t0 where t0.RefDate*/ '[%1]'
declare @refdt2 date
set @refdt =
/*select 1 from jdt2 t0 where t0.RefDate*/ '[%2]'
WHERE T0.RefDate >= @refdt1 and T0.RefDate <= @refdt2
... the error message is now:
Must declare the scalar variable @refdt1
Note: Before adding these lines, the query works perfectly, and returns totals from the whole database (with dynamically generated column headings!)
Thanks

AMENDED QUERY:
declare @refdt1 date
set @refdt1 =
/*select 1 from jdt1 t0 where t0.RefDate*/ '[%1]'
declare @refdt2 date
set @refdt2 =

--------- I inserted the 6 lines above ---------------------
DECLARE @listCol VARCHAR(2000)
DECLARE @query VARCHAR(4000)
SELECT @listCol =
STUFF
( SELECT DISTINCT   '],['    +    CAST(month(T0.RefDate) AS varchar)
FROM  JDT1 T0
FOR XML PATH('')
), 1, 2, ' ') +   ']'
SET @query =
'SELECT * FROM
(SELECT Account, month (T0.RefDate) Month , Debit

------------------- I add the WHERE clause below --------------------
WHERE T0.RefDate >= @refdt1 and T0.RefDate <= @refdt2
GROUP BY Account, RefDate, Debit
) S
PIVOT
Sum(Debit)
FOR Month IN ('+@listCol+')
