RowKeySetTreeImpl.toString() should be more defensive to avoid null pointer
exceptions
--------------------------------------------------------------------------------------
Key: TRINIDAD-1286
URL: https://issues.apache.org/jira/browse/TRINIDAD-1286
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 1.2.9-core
Reporter: Max Starets
RowKeySetTreeImpl inherits toString() implementation from AbstractCollection.
AbstractCollection.toString() is calling iterator(), which is causing a null
pointer exception when the collection model is null.
The call stack is the following:
