No, this should not work to my knowledge
The reason is that the facet is a key in a map to a component. Hash
map keys are not dynamic. If they even stored an EL expression, they
would not be evaluated at the right time for what you are trying to
do.
If you use JSP, you could use ${}, and for facelets, this would be
evaluated at compile time. Either way, the var would not be populated.
The very nature of what you are trying to do is wrong I am afraid. A
facet is a component. Components are built during compile time. Data
tables are evaluated at run time. As a result, you are trying to have
the data table dynamically add and remove facets from a component
while the loop is occurring.
To do this, you will have to either (1) create a facet for every
possible folder type or (2) use c:forEach to build the components
during compile time.
In addition, I don't even see why you would want to do this. You only
have one facet, so all nodes would look the same, what would changing
the name of the facet give you? Just use one node type in building
your tree model for folders.
