UIXCollection holds onto request scoped value objects
-----------------------------------------------------
Key: TRINIDAD-1570
URL: https://issues.apache.org/jira/browse/TRINIDAD-1570
Project: MyFaces Trinidad
Issue Type: Improvement
Components: Components
Affects Versions: 1.2.10-sandbox
Reporter: Venkata Guddanti
When a Collection Component for e.g. a UIXiterator has a value attribute bound
to a request scoped bean. This request scoped bean may have large amount of
data. UIXCollection has some state (_state) that holds the _value and the
CollectionModel (which might be internally holding onto the underlying data).
Since we are holding onto large amount of data between requests, the
scalability of the server can get effected.
we should make the ModelUtils change to support WeakReferences. If for some
reason we can't do that (because we are using JSF API's for wrapping the data),
the safe thing is to change the above logic to:
_value is a weak reference
if (model == value), _model is a weakReference, otherwise it is a strong
reference
This way we will not hold on to
