-----------------------------------------
Summary: ChangeManager does not apply changes that are added in
the renderer response before phase
Key: TRINIDAD-2323
URL: https://issues.apache.org/jira/browse/TRINIDAD-2323
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 2.1.0-core
Reporter: Andrew Robinson
In order to re-order components for components that have not yet been built yet
(ones that will be created by the JSP tags during the buildView call of the
RENDER_RESPONSE phase), the change manager will not apply the changes for a
ReorderChildrenComponentChange added at that time.
Use case:
For each loop on the page and the user wants to add a new item to the beginning
of the iteration. Because the new component does not exist yet, the user uses
<f:view beforePhase="...EL..."> to have a callback. In tha callback, the
backing bean adds a ReorderChildrenComponentChange to the change manager. That
change will not be applied until the next request.
The change should be applied immediately or at least after all of the phase
listeners have been fired.
Right now the changes are being applied at the end of the build view, but
before the view phase listeners have been fired.
The current alternative now is to not use the components to get the current
IDs, but for the backing bean to know the IDs of the components before they are
created and add the change during the INVOKE_APPLICATION phase
