Accessing Set Entities

Set entities are treated as one-dimensional arrays, each element being an object with a value and a label property.

You can access the elements of a set with the square bracket [ ] notation. Set entities are simple arrays and it is very common to iterate over them.

For more on loops and the <vdl-repeat> element, see Using Loops with Arrays and Sets.

If you wish to extract individual elements from a set entity, you need to protect the statement with a guard:

<span vdl-text="=scenario.entities.RISK.length && scenario.entities.RISK[0].value ?
scenario.entities.RISK[0].value :
'' ">
</span>

By default, Set data is sorted based on the data type. You can provide custom sorting and/or change the sorting direction to descending, for more, see VDL Set Sorting.
