Here´s my real-world use:

That data is in JSON format and transferred via HTTP to a 4D Server.
The server stores that data in an object field (which

Fusion charts will allow you to set an on click event handler in javascript.

Jeff,
Well, thanks for trying to be the cranky old man instead of me. But just
won't do. Now I have to rant.
My skepticism regarding using object fields for the purposes should be
pretty obvious to anyone that's paid attention.
Regarding the Summit demo...I watched the video and thought that it

Absolutely.
I exclusively use object fields for additional data and storage of connected
information to a specific data row, such as record and field history, specific
item settings etc.
All of these will NOT be queried on.
There are cases where I use object fields for variable data structures, b

Hi Jeff,
This is a great idea, I had not thought of it. Let me repeat it back to
see if I have it:

on the 4D Server calls "New Log File" every 10 minutes. Code in the loop
then calls LEP to a script to transfer the last

That was my first thought too, but I can change the query string to "Ralph" and
it still does a sequential scan of the table, returning no rows.

Maybe there is an issue with @ character in the search string ...
I've no idea how to circumvent it.

Trying to figure out why our experience with QUERY BY ATTRIBUTE is so different
than the demos at the last 4D Summit.
We're running 4D Server 16.2 64-bit on Windows. The Invoices table has about 9
million rows, and we added an index to the Extra field in this table which is
an object field.

Ok, I tested a regular list of [Contacts], where the fields are side by side on
1 row. Editing works here.
However, if you make the detail section bigger and put the fields vertically,
editing is no longer possible… bug?

[Customers]
The subform is set to display the [Contacts] Output form, is set to ‘Edit in
