Fabrizio, that seems wrong. With that implementation, when would you
ever use the "name" attribute without ${}? A proper implementation
should look like either:
<display:table name="userList">
or
<display:table name="${listName}">
The second case uses double indirection, so it would only be used in a
situation where you have several different lists in the page context
that you can choose from, keyed by names, and the name of the list you
choose needs to be dynamic. Granted, this is a very odd-sounding use
case, but it could happen. The reason that EL tags seem weird in this
case is because the value of the "name" attribute should be a variable
reference. EL tags make much more sense in attributes that are
constants, e.g.
<display:table name="userList" cellspacing="${cellspacing}">
