How can I get RolesIndex from the API?

[Anonymous]

Hi there, when there are multiple columns mapped in the same fields panel,  like that

in the metadata -> columns -> rolesIndex  a vector is created containing the index of each field

But in the interface of the API this not acessible. I checked the DataViewUtils (Introduction to use Data view utils in Power BI visual in Power BI embedded analytics for better emb...) , but its just help to find the specific role in different fields.

How i get that specific property named rolesIndex in my code?

Thanks.

Gabriel.

Hi @Anonymous,

I would say that if you want a supported way to do this, then it's probably better to make a request in the repo for the feature.

A hacky workaround would be to refer to it explicitly like this, but it's going to get resolved as an any type, and you may need to write some safety checks around the object properties in the chain, otherwise your visual will potential experience some unintended side-effects:

dataViews[0].metadata.columns[i]['roleIndex']['statusImg'][0]

It might be worth stepping back to see if this is absolutely the way to solve what you are trying to do though - perhaps if you can share enough info and code around what you are trying to achieve, along with some sample data then perhaps we can take a look at a more supported approach?
