NPE when trying to report an exception involving an instance that returns null
for toString()
---------------------------------------------------------------------------------------------
Key: TAPESTRY-2570
URL: https://issues.apache.org/jira/browse/TAPESTRY-2570
Project: Tapestry
Issue Type: Bug
Components: Framework
Affects Versions: 4.1.5
Reporter: Patrick Moore
Priority: Minor
Fix For: 4.1.6
Code from ExceptionAnaylzer:
(line 178) stringValue = value.toString().trim();
if (stringValue.length() == 0)
continue;
------------------------
value.toString() returns null. Seems somewhat useless code.....
I don't understand why the stringValue.length is being checked for it being an
empty string because then stringValue is not used. And no comments to help :-(
