q-table selection not working with [row-key="--index"] after quasar upgrade

[jitendra16]

I don’t have unique key in my data set, so i used --index property for row-key and i was able to select single/multiple. But after upgrading to v1.4.5 its not working. I want to know that how to select single/multiple records when data rows don’t have unique key.

@jitendra16 https://forum.quasar-framework.org/topic/4723/quasar-v1-4-4-released __index was private and has been removed for performance reasons, what you could do is assign a key prop on your data array.

Ie.

//script
const dataWithIdx = origData.map((val,idx) => ({...val, index: idx}))
...
   data: dataWithIdx,
...
<template>
...
  <q-table ... row-key="index" ...
...

@metalsadman i also did this work around and it worked perfectly. I wanted to know that, is there any quasar way to do it?
