> NullPointerException with multiple XMLMenuModel beans in one page
> -----------------------------------------------------------------
>
> Key: TRINIDAD-708
> URL: https://issues.apache.org/jira/browse/TRINIDAD-708
> Project: MyFaces Trinidad
> Issue Type: Bug
> Components: Components
> Affects Versions: 1.0.2-core, 1.2.2-core
> Environment: Trinidad 1.0.3-SNAPSHOT
> Reporter: Andrew Robinson
> Priority: Blocker
> Attachments: xmlMenuModel.patch
>
>
> A page that uses more than one XMLMenuModel beans (two different sources)
> causes a NullPointerException. There doesn't seem to be any work-around
> except to not use XMLMenuModel functionality, hence why I reported this as a
> "Blocker".
> See the forum reference for the details on the problem and how to reproduce
> it:
> http://www.nabble.com/-Trinidad--Exception-with-XMLMenuModel-usage-tf4432359.html#a12645175
> The problem seems to stem from the fact the code uses a single request
> variable to store the model. This means that if there are multiple models,
> only the first one gets stored, and all the rest are thrown out essentially.
> Suggested fix from what I have seen:
> The root model should be cached per source, not just one instance.
> Current code:
> requestMap.put(_ROOT_MODEL_KEY, this);
> As you can see, only one instance can ever be created per request.
