initCause in errorFilter causes IllegalStateException
-----------------------------------------------------
Key: TAPESTRY-2353
URL: https://issues.apache.org/jira/browse/TAPESTRY-2353
Project: Tapestry
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.0.11
Environment: Tomcat 5.5.25
Reporter: Josh Canfield
Having <t:unless> with no test parameter throws a TapestryException.
I've also seen this when trying to @Inject a service which hasn't been
configured.
When the errorFilter gets the exception it finds that there is no cause set,
and tries to init one. This throws the following exception:
java.lang.IllegalStateException: Can't overwrite cause
