Required Validator can produce NullPointerExceptions
----------------------------------------------------
Key: TAPESTRY-2253
URL: https://issues.apache.org/jira/browse/TAPESTRY-2253
Project: Tapestry
Issue Type: Improvement
Components: tapestry-core
Affects Versions: 5.0.12
Reporter: Kristian Marinkovic
the validate method of the Required validator contains following code line:
if (value == null || value.toString().equals(""))...
if the toString method returns null an exception will occur (happened to me
accidentally :))
this code line should at least be changed to:
if (value == null || "".equals(value.toString())... to prevent NPE
