NoRowAvailableException in ChildPropertyTreeModel
-------------------------------------------------
Key: TRINIDAD-1796
URL: https://issues.apache.org/jira/browse/TRINIDAD-1796
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 2.0.0.3-core
Environment: All
Reporter: Kamran Kashanian
The contract for the Trinidad CollectionModel/TreeModel setRowKey() API is
that this API should silently fail if an incorrect row key is passed in as a
parameter. The caller is then required to call isRowAvailable() to check for
a valid 'current' row in the model before doing anything with the row data.
The JSF DataModel 'setRowIndex()' API behaves the same way.
The Trinidad ChildPropertyTreeModel implementation, however, can throw a
NoRowAvailableException if the setRowKey() API is called with an invalid row
key in the key path.
The proposed fix is to check for valid row keys in the key path (by calling
isRowAvailable on each child model) as the setRowKey API implementation
traverses the tree model hierarchy and sets the current row at each level.
I will submit a patch.
