[#5853] - Listed values defined as Strings

Hi,
I am trying to filter my reports using a list of values or SQL queries, Each time I use the multiselect option I get an error stating the field is not an integer. I believe this is because the lists are defined as strings.

I tried to use the work around where defining the coloumn as a VARChar, But this brings up a similar issue.

When using single Select queries though it works fine, because the end parameter is set as a Integer.

I use the where $X{IN, MyIntgerColoum, Myparam}
