Re: direct access to ArrayList elements by index possible?

[Mert Çalışkan]

Yes Phil,

<h:inputText value="#{backingBean.list[2]}" /> is right.

But be careful about the scope of the list. If you are using it for another pages make it a managed-bean.

Well, that is very nice to know :-)

And what would be the proper syntax for doing this? 

The values don't seem to get updated in the backing bean, so I guess there's smth wrong with my syntax... (?)

Hi List,

Does anyone know whether it is possible to directly access the
elements of an instantiated ArrayList by their index?

So if I would have in my backing bean:

ArrayList<String> list = new ArrayList<String>()                // with e.g.
elements from index [0] to [4] having precise semantics & being
instantiated in the bean constructor

--> is there a way to do, on a page, stuff like:

<h:inputText value="#{backingBean.list [2]}" />

It would avoid having to create one dedicated proxy variable per
index and handling the synchronization between these two.

Thanks for tips,
Phil
