Hi,  
I have a table which is bound to a dataset tag.  
I have it set as a bi-directional binding.  
I have the table set up to enable editing, but when I edit a cell it doesn’t update the tag.  
Is there a way around this?

You have to make an onEditCellCommit event in the table.

Which then could write to its own props (or directly to the tag)

I tried to do this and it gives me an error "Object is unsubscriptable"

Brian, you really need to show us what you did and what exactly is giving you that error. Show your onEditCellCommit code and any associated message handlers. Please see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831).
