Jeanne Waldman commented on TRINIDAD-803:
-----------------------------------------
Checked this patch into 1.2.3.1.
It needs to go into trunk and 1.0.4-prerelease as well(since it will get into
1.2.4 and we need to keep 1.0.4 and 1.2.4 in sync).
> NPE in UIXCollection saveStampState()
> -------------------------------------

> Key: TRINIDAD-803
> URL: https://issues.apache.org/jira/browse/TRINIDAD-803
> Project: MyFaces Trinidad
> Issue Type: Bug
> Components: Components
> Affects Versions: 1.2.3-core
> Environment: All (Tested on Windows XP SP2)
> Reporter: Kamran Kashanian
> Assignee: Jeanne Waldman
> Fix For: 1.2.3-core
>
> Attachments: trinidad-1.2.3.stamp-state.patch,
> trinidad-1.2.3.stamp-state2.patch
>
>
> Some recent optimizations were added to the saveStampState() method in the
> UIXCollection component in Trinidad 1.2.3. Under certain circumstances
> (certain combination of stamped components inside the UIXCollection), this
> change can cause a NullPointerException.
> Specifically, if a stamped component contains a combination of facets, some
> of which have state to save and some have no state, the saveStampState()
> method can create a state array with null values for facet names. The null
> facet names can later cause a NullPointerException in restoreStampState().
> Attach is a patch for the saveStampState() method to avoid saving null facet
> names.
