>             Project: Tapestry
>          Issue Type: Bug
>    Affects Versions: 5.0.11
>            Reporter: Alexander Gavrilov
>            Assignee: Howard M. Lewis Ship
>             Fix For: 5.0.13

>   Original Estimate: 0.08h
>  Remaining Estimate: 0.08h

> when displayed exception contains at least one write-only property tapestry failing to render error page.
> java.lang.UnsupportedOperationException: Class ui.Exception_detail does not provide an accessor ('getter') method for property 'faultCode'
> at org.apache.tapestry.ioc.internal.services.PropertyAdapterImpl.get(PropertyAdapterImpl.java:81)
>         at org.apache.tapestry.ioc.internal.services.ClassPropertyAdapterImpl.get(ClassPropertyAdapterImpl.java:81)
>         at org.apache.tapestry.ioc.internal.services.ExceptionAnalyzerImpl.extractInfo(ExceptionAnalyzerImpl.java:105)
>         at org.apache.tapestry.ioc.internal.services.ExceptionAnalyzerImpl.analyze(ExceptionAnalyzerImpl.java:50)
> 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;
