Multiselect doesn't load selected options when component is initialized

[Juan Gabriel Giraldo]

I have a problem with multiselectdropdown component. 

I'm trying to load selected options into a multiselect.

When it's in the hook ngOnInit (also i tried with ngAfterViewInit), i get data from an API using HttpClient class and that data is saved in operatorList variable. That works well, but if i try to get an ID from the list an try to select an option of the list, that doesn't works, and there's no any message of error in the console.

But if i try to do the same process when the component is initialized, executing the same lines of code with a button and that works well.

I would like to know about how solve this issue, if the component has any hook, state or propertie to know when Multiselect is initialized and i can select options

The error occurs when a request is made to an API to load the information from the multiselect. When the request is executed and is waiting for a response, when the response arrives, the same procedure of selecting the values in the multiselect is carried out, at this point is where the error arises, it does not load the information.
