WD: Select Options shows empty ranges

Question

Hi there,
Im using select options in my wd application... I defined a few fields (numeric, dats and so on).  I was expecting that the select options in wd works like the normal ones in normal abap report.
But when I try to read the results from select options , the result range table has no sign or option value (low value ok) ... when I reach the result to a Select statement a shortdump happen with the notice there is no sign or option value in the IN parameter of the Selection statement.
Does any one know if this is standard behavior of WD select options ?
