This is probably a lack of my Java knowledge... I got this from someone at IA to get a full list of all of the default alarm props: > [@system.tag.getAlarmStates alternative?](https://forum.inductiveautomation.com/t/system-tag-getalarmstates-alternative/27803/13): > > Update: You can get the alarm default values using: from com.inductiveautomation.ignition.common.alarming.config import CommonAlarmProperties, AlarmModeProperties properties = {} properties.update(dict((s.getName(), s.getDefaultValue()) for s in CommonAlarmProperties.values())) properties.update(dict((s.getName(), s.getDefaultValue()) for s in AlarmModeProperties.values())) I'm trying to do something similar but for tags in general (history would be good as well). I searched the API and found `com.inductiveautomation.ignition.common.tags.config.BasicTagConfiguration` and `com.inductiveautomation.ignition.common.tags.config.BasicTagConfigurationModel` which seemed to be what I was after maybe... and proceeded to try to use the `getValues` method, but got an AttributeError for both: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/e/1e8c1ec3b0b3cee1932bb95ab503efa86881c034.png) Can someone explain this, and point me in the right direction? @paul-griffith? 🙂 ---

You are trying to use an instance property (really translated from NetBeans getter .getValues()) on a class. You need to use it on an instance. ---

CommonAlarmProperties is an enum class, which naturally has a values() method (on the class). Distinct from a getValues() method of `BasicTagConfigurationModel` which is not an enum. Your constructor looks fine. I don’t know why it doesn’t work. (But I haven’t explored in this area. You can keep blazing a trail…) ---

You’re not doing anything wrong (necessarily), it’s just that BasicTagConfigurationModel doesn’t do what you expect it to do. It looks like, at a glance, it’s still ‘just’ an extension of the PropertySet model that everything else tag related uses - TagConfigurationModel and its related members are extended to allow, for instance, ‘layering’ of snapshots over each other, but you still need to derive those snapshots from somewhere. Ultimately, the more helpful thing for what you’re trying to do is probably going to be using `com.inductiveautomation.ignition.common.tags.config.BasicTagConfiguration#createEdit(com.inductiveautomation.ignition.common.tags.model.TagPath)`, then extracting each property (or its default) using `com.inductiveautomation.ignition.common.config.PropertyValueSource#getOrDefault`. To get a static reference to the properties you care about, refer to the aptly-named `com.inductiveautomation.ignition.common.tags.config.properties.WellKnownTagProps`. ---

Thanks Paul, that’s gotten me somewhere. Onto the next dumb question 🙂 How would I get a list of all of the fields of `WellKnownTagProps`? I can use `dir()` but that will return methods and everything else as well. Is there something else I can use? Also, I actually don’t think I need to use `BasicTagConfiguration*` or `PropertyValueSource` at all as the `WellKnownTagProps` has a method `getDefaultValue()`. ---

> [@nminchin](#): > > How would I get a list of all of the fields of `WellKnownTagProps` ? I can use `dir()` but that will return methods and everything else as well. Is there something else I can use? Java's reflection API, though I haven't done a lot with it from Jython. E.G, something like this from the class definition, translated to Jython: > There's no central registry or anything; as of 8.0 a key aspect of the tag configuration model is that any tag can have any number of properties, and the 'actors' that actually _do_ anything with the tag configuration simply 'ask' for what they care about.
