---------------------------------------
Hi Guys. We are building a presentation framework for a top banking company
using Trinidad Faces and have run into this issue. We cannot make any progress
unless Trinidad allows us to created two or menu models. Can you please let us
know if any one is working on this issue or are there any plans of fixing this
in the near future. Any work-around is also acceptable for time being. I
couldn't find the name of the author from XMLMenuModel class, so, I don't know
who to talk. The forum has some replies from Adam Winer from Oracle but I'm not
sure if he's still associated with this.
Thank you.
> 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
>
> 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.
