Leonardo Uribe commented on MYFACES-2428:
-----------------------------------------
Committed disable of use facelet generated id.
It was notice that vdl.buildView is used in two cases:
1. Construct the view.
2. Restore transient components used to write facelets markup (usually
instances of UILeaf like UIInstructions).
It was necessary to correct the method isFilledView() and the algorithm to save
view, because transient components should not be taken into account to save the
position of the component in the child list.
> Id generation for facelets cause problems with htmlunit 2.4 or lower

> Project: MyFaces Core
> Issue Type: Task
> Components: JSR-314
> Reporter: Leonardo Uribe
> Assignee: Leonardo Uribe
>
> The id generation strategy is critical to allow partial state saving works
> correctly, because all component state is saved on a map, and the clientId is
> the primary key for it.
> Actually, we just pass the facelet generated id for each tag as a seed for
> UniqueIdVendor.createUniqueId(FacesContext context, java.lang.String seed),
> This id cause an exception in htmlunit version 2.4 or lower (in 2.5 this was
> fixed).
> The objective of UniqueIdVendor interface is reduce the variation when ids
> are generated. The ideal case is that for any facelet page the generated ids
> assigned to components should remain the same no matter if the model changes
> by some reason.
> The problem starts when it is used <c:forEach> or <c:if> tags, because its
> behavior depends on the "model" state in a point of the time. The id
> generated by facelets is depends on the facelet "alias" page name, a counter
> id from CompilationManager.
> We need to do multiple tests for worst case scenarios, and try to define an
> strategy to reduce the variability of ids, providing proper "seeds" for it.
> Suggestions are welcome
