Comments on: Using Custom Type Marshallers in BlazeDS http://flexblog.faratasystems.com/2010/01/09/custom-type-masrhaller-in-blazeds A blog about our experience with Adobe Flex Sun, 15 Jan 2012 16:29:29 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Nicolas http://flexblog.faratasystems.com/2010/01/09/custom-type-masrhaller-in-blazeds/comment-page-1#comment-68136 Nicolas Fri, 26 Mar 2010 07:56:06 +0000 http://flexblog.faratasystems.com/?p=555#comment-68136 There is a way to deal with your porblem, but it is tricky. Basically, you need to use a BeanProxy that will look at the return type of your method and based on that and the fact that it is null, return NaN instead. the tricky part is that you need to register your BeanProxy against the classes that will have to use that customization. So the BlazeDS 3 way as it is done, you're supposed to have either a common superclass or an interface on all your DTO. You can find more info on that in that bug : http://bugs.adobe.com/jira/browse/BLZ-305 There is a way to deal with your porblem, but it is tricky.

We have Long variables in Java which are null but which are converted to 0 in AS . We would like to map them to NaN in order to differentiate between null and 0. Is there a way to write a custom encoder ? i would also like to tackle the opposite problem. We have Long variables in Java which are null but which are converted to 0 in AS .
