Ok, now we have a clear situation. The "name" attribute is evaluated
as an OGNL expression so in this case everything enclosed will be
parsed and treated as expression, from inner to outer.

Using "%" forces an additional evaluation but enclosing it in a single
quote (') means you expect a String so this expression
'%{#attr.mapKey}' should only return '12345-123', then
"accountAllocation[]" is evaluated as a map with a key (in this case
with a String key).

So using single quotes should do the trick in your case.
