Action filter (calling an action just for a specific entity)
To restrict a trigger only to certain entities you can put the entities inside of a pair of brackets at the end of the elb-action attribute. If the trigger event gets called the result will only include the property values from the specific entities.
<!-- setting a filter of an action --><div elb="foo" elb-foo="a:1"><div elb="bar" elb-bar="b:2" elb-action="load:hello(bar)">{"action": "hello","entity": { "type": "bar", "data": { "b": 2 } },"trigger": "load"}</div></div>
