Hi Josh,
I've been running a live Tapestry app on Ubuntu server with openjdk-6-jdk for
some months now without a problem except a clash with ImageJ which was resolved
by upgrading ImageJ. Like you, the development was on OS X, and built on OS X,
ie. I don't recompile for Ubuntu. My Ubuntu java looks the same as yours...
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.2) (6b20-1.9.2-0ubuntu1~10.04.1)
OpenJDK Client VM (build 19.0-b09, mixed mode, sharing)
Here's an example that works fine:
@Property
private List<AdvertMod> _advertMods;
@Property
private AdvertMod _advertMod;
<tr t:type="Loop" t:source="advertMods" t:value="advertMod">
so I have no idea what's causing your problem. Very odd. A spurious thought:
maybe calling the variable "list" is confusing it?
