Placing tr:train outside of a form results in an exception instead of a
descriptive warning.
--------------------------------------------------------------------------------------------
Key: ADFFACES-343
URL: http://issues.apache.org/jira/browse/ADFFACES-343
Project: MyFaces ADF-Faces
Issue Type: Bug
Environment: Sun Java System Application Server 9.1
Facelets 1.1.11
Affects both : faces-1_2-061214 and stable-06-dec branches
JDK 1.5.0_10
Windows XP Service Pack 2
Reporter: Graeme Steyn
Priority: Minor
When a tr:train component appears outside of a form, an exception gets
generated that stops the application, rather than logging a descriptive
warning. The exception appears as follows:
java.lang.NullPointerException
