Key: TAPESTRY-2422
URL: https://issues.apache.org/jira/browse/TAPESTRY-2422
Project: Tapestry
Issue Type: Bug
Affects Versions: 5.0.11
Reporter: Alexander Gavrilov

Fix For: 5.0.12

it seems like error in extractInfo method, which does not analyze can it read
property or not before invoking adapter.get(). So, it is simple to patch
Instead of
Object value = adapter.get(t, name);
if (value == null) continue;
Use
PropertyAdapter pa = adapter.getPropertyAdapter(name);
if (!pa.isRead()) continue;
Object value = pa.get(t);
if (value == null) continue;
