Re: [rules-users] Drools Bug: Custom Operator with Maps results in Mvel Error

Hi Edison, Thanks for the tip, I realize how I can use Integer type now. The following should hopefully be sufficient to reproduce the error that I am experiencing. Please me know if you need further clarity. I'm continuing to search through posts to and debug. I'll post back if I find the solution. -- Model DRL --- package com.uday.targeting declare Profile    pageFreq: Map end -- // In a driver, create a fact type for Profile, given that it is defined via a declarative model. FactType profileType = kbase.getFactType("com.uday.targeting", "Profile"); // Define a HashMap for pageFreq, and set the number of times a user visited page tagged as "internet" to 2. Map<String,Integer> pageFreq = new HashMap<String,Integer>(); pageFreq.put("internet", Integer.valueOf(2)); // Associated the pageFreq Map with the Profile fact. profileType.set(profile, "pageFreq", pageFreq); // insert the profile into working memory wm.insert(profile); --- UdayRule DRL --- package com.uday.targeting rule "Testing out UdayCompare Custom Operator"        ruleflow-group "udaytesting"        when                profile : Profile()                Integer( this udaycompare[gt] 1 ) from profile.pageFreq["internet"]        then                System.out.println("Yippie it works!!"); end --- Error thrown:  Unable to build expression for 'from' : 1 'profile.pageFreq["internet"]' : [Rule name='Testing out UdayCompare Custom Operator'] -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-Bug-Custom-Ope...
