Not sure if I totally understand but - here's another try.... I usually have a class that 'wraps' the collection used in the select list. it has static methods like getSortTypeValueFromLabel & getSortTypeLabelFromValue. I use these in my action class to translate between the formBean (uses the display labels) & the business logic (uses the values). I do it this way - it feels right - the collection wrapper class is part of the business logic that is designed for servicing GUI's - the validation logic isn't cluttered with converting from label to values.
Here's an example of another approach - for Customer Type. your business logic can have:- set CustType (String custTypeValue) & setCustTypeByLabel(String custTypeLabel). The conversion is called from inside your validation class. I can't see anything wrong with that either. Hope that helps - Keith. --- Rob Parker <[EMAIL PROTECTED]> wrote: > Thanks Keith - I probably didn't explain my problem well enough. I am not > having problems with the <html:options> at all.
