[rules-users] Keep getting error trying to access value in hash map.

[samd]

I'm trying to extract the value from a hashmap after first extracting a key
and I keep getting the same error.

Here is the rule information:

target: Target();
perm: PermissionCheck(target == target, action == "edit", granted == false);
primaryKey : TargetId(targetNum == 1) from target.codes.keySet();
primaryCode : TargetCode() from target.codes.values[primaryKey];

Here is the error:

Caused by: javax.el.ELException: /layout/test.xhtml @25,111
rendered="#{s:hasPermission(target,'edit')}": org.mvel.CompileException:
