Text field validation causes NullPointerException
-------------------------------------------------
Key: TRINIDAD-969
URL: https://issues.apache.org/jira/browse/TRINIDAD-969
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 1.0.5-core
Environment: Win/XP, JBoss/Tomcat, Facelets
Reporter: Steve Horne
This bug manifests itself when an inputText field is used without a label
attribute and is required, for example:
<tr:inputText simple="true" required="true"/>
AND The page also contains a messages tag:
<tr:messages/>
Entering nothing into the field results in a message displayed that the field
is required. Entering only whitespace characters results in a null pointer
exception:
16:48:03,927 INFO [STDOUT] 16:48:03,927 ERROR [[faces]] Servlet.service() for
servlet faces threw exception
java.lang.NullPointerException
