`xmmselect` does not seem to recognize the screening criteria used to generate a filtered event list.

Let's assume that you have filtered an event list via xmmselect, using the parameter destruct=no. If you re-load it in xmmselect, its selection expression is not recognized, and is not applied in the generation of further scientific products.

In order to overcome this problem, use the expression SELECTED in your xmmselect screening expression widget. This can be combined with any other filter expressions. For instance: SELECTED && PI in [300:1500]

Future versions of xmmselect will be able to detect this for you.
