Hi,

While I was going through docs for adding conditions on actions in Watcher, I had a few doubts.

Is there any way I can access the `payload._value` of transform block inside the condition on watcher?

Ex.

```auto
"transform": {
      "type": "script",
      "status": "success",
      "payload": {
        "_value": 0.44380686824204707
      }
    },

```

Example condition:

```auto
"condition": { 
        "compare" : { "ctx.payload._value" : { "gt" : ctx.metadata.threshold } }
}

```

In other words, alert only when the above condition succeeds.

In case I am trying to add a condition to action, it is throwing an error saying `invalid [compare]`.

The action I am performing is `log`.

You can add data into the context like this `ctx.vars._value='0.44380686824204707';`

```
  "transform": {
  "script" : "ctx.vars._value=0.44380686824204707"
},
```

@elastock This is not working. It gives:

```auto
Watcher: [parse_exception] could not parse action [inlined/transform]. unknown action type [type]

 OK

```

This is my action:

```auto
"actions": {
    "log": {
      "transform": {
        "type": "script",
        "status": "success",
        "script" : "ctx.vars._value=0.44380686824204707"
       },    
      "logging": {
        "level": "info",
        "text": {
          "source": "Percentage change for upstream from previous day: {{ctx.payload._value}}",
          "lang": "mustache"
        }
      }
    }
  },

```

Let me know if something is wrong. Also, the value `0.44380686824204707` is not static, it will change after transformation.

Okay. I think I got this working. I didn't need to use transform, I just needed `condition`.

just to clear things up: the transform is always executed after the condition - and only if the condition is true.
