Thanks for the response Dan. I understand the name var is just a variable.
In my example, name is not a getter in the backing bean - it is simply the
cursor/ref/var as shown in the code below. The data contained within the
list is a simple list of strings. The fact that the data provider is just a
list of strings as opposed to POJOs with accessors that can be referenced is
the problem. Since the value is just a string there's no field key -
#{sourceVarName.value.????} therefore I am unable to get at the underlying
value. I'm guessing from your response that "simple" values have to be
wrapped with a bean that exposes an accessor?
Example #2 creates a table with pojos in the provider i.e., Name objects
with accessors (field keys) such as "first" and "last" and as such you can
reference the dataprovider values with a fieldkey; e.g.,
#{sourceVarName.value.first}. This works fine for me and I use the pattern
regularly. Again, the problem I have encountered is how to deal with
"simple" values i.e., a ListDataProvider populated with Strings. In the
example I provided, the "names" list is just a list of strings. I trust
this clarifies my intent.
Thanks for your help!
