Key: TRINIDAD-972
URL: https://issues.apache.org/jira/browse/TRINIDAD-972
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 1.2.6-core, 1.2.7-core
Reporter: Matt Cooper
Assignee: Matt Cooper
UIXIterator.processFlattenedChildren() and its underlying UIXCollection cache
is not initialized or flushed properly. This becomes a problem when you nest
iterators. During normal use of non-flattening iterators, its cache gets
initialized and flushed during the encodeBegin() of its parent class,
UIXCollection. During a flattened use case (e.g. the parent component of the
iterator has a renderer that uses UIXComponent.processFlattenedChildren()),
encodeBegin() does not get invoked and thus the cache is neither initialized
properly nor flushed. We need to expose a non-public method on UIXCollection
that invokes its private initialization and private flushing functionality so
that UIXIterator which extends it can invoke this new method during its
UIXIterator.processFlattenedChildren() and thus so that nested iterators where
the inner iterator is flattened can work. This change will have zero impact on
the non-flattened use case so there is no risk to existing applications in that
scenario.
