The plan is to construct a form where one can enter Values like "5a" or "10c" - it's always a number and a character. To make it comfortable I thought about two selectOneListbox. One showing the numbers, the other one shows the characters. I need the combination of these both as a String for a query.
Has anybody an idea? I tried to provide a byte and a char field in my session bean which results in a "could not set field value" error when loading the XHTML page.
