I have an RPC call with a signature like public List<String> SomeCall
(SomeObj) { return anArrayList; } which failed.
Policy file was deployed and the file had ArrayList, true in the file.
The only real information available was the stack trace it left in
catalina.out (see below).
I'm running gwt1.52, a Spring/Hibernate stack on the back end with (a
probably early version of) gwt-sl. The problem manifested itself in
eclipse. When I changed the return value to String[] eveything worked
fine.
Does anyone know, is it not OK to use List<String> as a return
specifier?
