Sometimes I also face similar problems - clicking on an ABMTable and not getting back information.
Usually, the problem goes away if I run my program in Debug mode.

Is that not a B4JS thing? I often use a map as the tag whenever possible.
Having said that, I have found an ABM control where the tag only accepted a string rather than an object.... Probably an oversite in creation...

So, with this explained (again - how quickly we forget).... use the primary key of your record (MySQL), in the first cell as your row (record) ID.
I do this with every ABMTable that derives its' content from a database table and see no reason not to do so (how else?).

In the rare instance where I need to build a table based on a compilation of many other datasets (associated tables) - (temp disk or in-memory), I always create a Primary Key to deal with the selected record. Otherwise, how can one determine what specific data you are referencing?

Unless you provide a specific example of what you are trying to accomplish, no one will take the time to "mind read" what is the issue.

As a caveat and sympathetic , I don't use ABMTables without an underlying data table. I know these uses exist, just I am not familiar. Perhaps someone can shed some light on what I am sorely missing, as it may be extremely useful moving forward.
Thanks
