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: unable to resolve property: values at com.sun.facelets.el.TagValueExpression.getValue(TagValueExpression.java:76) at javax.faces.component.UIComponentBase.isRendered(UIComponentBase.java:390) ... 61 more Caused by: org.mvel.CompileException: unable to resolve property: values at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain(ReflectiveAcces sorOptimizer.java:288) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.optimizeAccessor(ReflectiveAcce ssorOptimizer.java:109) at org.mvel.ast.VariableDeepPropertyNode.getReducedValueAccelerated(VariableDeepPropertyNode .java:29) Thanks -- View this message in context: http://www.nabble.com/Keep-getting-error-trying-to-access-value-in-hash-m...

It was my understanding based on other posts that was the required syntax for dealing with with a Map in Drools. I'll try what you suggest.
