Hi, I tried this. No problem at all. I can use enums also like this: io: InputObject(type == InputObject.Parameter.PARAMETERNAME) Only this causes the error: private HashMap<Parameter, String> stringParameters; public HashMap<Parameter, String> getStringParameters() { return stringParameters; } public void setStringParameters(HashMap<Parameter, String> stringParameters) { this.stringParameters = stringParameters; } / io: InputObject ( stringParameters[InputObject.Parameter.ParameterName] ==/ /"something") -//> Field/method 'InputObject' not found for class 'com.rules.InputObject'Rule />/ Compilation error// / If I use String instead of Parameter it works again: private HashMap<String, String> stringParameters; / io: InputObject ( stringParameters["somestring"] ==/ /"something") / Thomas *Scott Reed* sreed at avacoda.com <mailto:rules-users%40lists.jboss.org?Subject=%5Brules-users%5D%20enums&In-Reply-To=d8ac9d7f0807280443j5c9edd90u2112c0e05a3c375f%40mail.gmail.com> /Mon Jul 28 09:10:48 EDT 2008/ Try a simple rule that just checks for any InputObject to make sure you have the class imported correctly.
