How do I get the meta data for the current index?

[LeoReubelt]

I use viewController.setCurrentIndex(new Index(values)) to set the current slice.
And when I show the meta data, I want to show the meta data for the current index.
But app.getMetaData(0)[00080018].value returns {[instanceNumber: number] : tagValue}.
But app.getMetaData(0)[00200013].value returns an unsorted array of instance numbers.
So if I can not get the instance number from the current Index, how do I get the meta data for the current index?

For now, this is not possible, I need to think on a solution...
