Hi Lian,=0A=0AIt seems to me that you are using Json-lib 2.0, which has a b= ug when serializing back to Java and the bean has an array property of non-= primitive type. It has been fixed for 2.1-SNAPSHOT. You may download a copy= from cvs and build yourself the jars or head to=0Ahttp://json-lib.sourcefo= rge.net/m2/repo/snapshot and download the latest snapshot.=0A=0APlease let = us know if it didn't work for you.=0A=0ACheers,=0AAndres=0A =0A------------= -------------------------------=0Ahttp://jroller.com/page/aalmiray=0Ahttp:/= /www.linkedin.com/in/aalmiray=0A--=0AWhat goes up, must come down.
