[jira] Commented: (TAPESTRY-846) Random error accesing pages:
Property " " has already been accounted for by the element at Annotation
...
[ http://issues.apache.org/jira/browse/TAPESTRY-846?page=comments#action_12371206 ]
Martin Dirichs commented on TAPESTRY-846:
-----------------------------------------
Also got biten by this issue (with tapestry-4.0).
https://issues.apache.org/jira/browse/TAPESTRY-696
really seems to be closely related, but there must be a different root cause than the
one fixed there.
I did some experiments and found out three things so far:
1. For me, the error only occurs with -Dorg.apache.tapestry.disable-caching=true.
2. It's quite definitely a race condition since the error occurs only occasionally.
3. There must be another issue than the one fixed in TAPESTRY-696.
In TAPESTRY-696, the solution seemed to be a synchonized block within
org.apache.tapestry.services.impl.ComponentConstructorFactoryImpl.getComponentConstructor().
Out of curiosity, I declared the whole method as synchronized, but the error still
persisted.
