Hi Dave, Ok, i've tried that one and it works like it should.
So that getter method works as kind of a "type hint" to the framework so that struts knows it has to convert the parameter "amount" to the given Map<Intger, Float> - Is that correct? Up to now I've only added getter methods to struts-actions when i really wanted to access some properties from my JSP. I never thought they would have an effect on the type conversion (and on using the right setter method). Anyway - problem solved. Thanks for your help and patience! André
