Here's a minimal example of my problem.
Again, the LDM::getObject() call AFTER the onSubmit()
call that changes the data does not result in a LDM::load().
There's a load() before the onSubmit(), but that's too early.
Anyone? What am I missing?
Thanks,

Pressing the button adds an entry to the drop down list,
but you can't see it without reloading the page.

What am I missing?
