I need to supply multiple "in the list" parameters at runtime for a report so my where statement is: Where columnname in ($P!{parameter}) The parameter class is java.lang.String. Is there a way I can set the Default Value Expression, Property, or anything else so the user does not have to remember to enter each value in 'quotes'? Currently the user has to supply something like 'A01','B99','XYZ' when responding to the parameter. They always remember the commas but they have trouble with the quotes (leave them out, use a double and a single, etc.) and then the report produces an error. Is there someway to automatically supply them or make them unnecessary? Thanks!
