SKIP_ITERATION forces visit of non-rendered components
------------------------------------------------------
Key: TRINIDAD-2078
URL: https://issues.apache.org/jira/browse/TRINIDAD-2078
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 2.0.0-beta-2
Reporter: Andy Schwartz
Assignee: Andy Schwartz
Certain tree visits, such as the PostRestoreStateEvent delivery visit, must
avoid iteration in stamping components (eg. UIData). Before the fix for:
TRINIDAD-2030 Honor SKIP_ITERATION FacesContext property
This was handled in UIXComponent.visitChildren() by checking for the restore
view phase.
As of the fix for 2030, instead of checking the phase id we now check for the
SKIP_ITERATION pseudo-hint.
While this works correctly for the PostRestoreStateEvent visit, it fails in
other cases. The problem: UIXComponent.visitChildren() falls back on a "facets
and children" traversal when SKIP_ITERATION is set, which means that we will
visit all children (both rendered and non-rendered) even when the
SKIP_UNRENDERED hint is set.
Thus, the combination of SKIP_ITERATION and SKIP_UNRENDERED is not correctly
supported with our current solution. Since this is a valid combination of
hints, we'll need an approach that correctly supports this.
