If road_assistance_2year is not '-' then it's a double. It works in Tomcat 6.0.13. Anyway I've solved the problem by adding a boolean variable to check for road assistance and now road_assistance_2year is always a double (either 0.0 or the price). But thanks for the casting, I didn't know I could do that in EL.
