Are the two actions both on the same table? Like they’re both on AccountsList, and then they’re supposed to adopt/remove from SelectedAccounts?

Yes.

The issue sounds like the Deselect Option doesn’t have the right context, since the action is on a different model than the one you’re trying to remove from. 

It’s a little roundabout, but to accomplish this you could do something like this with the remove row action…

1. Updates a Feld on a UI-Only Model and stores the AccountId


2. Toggles a checkbox in SelectedAccounts Model (ui-checkbox)

Then that SelectedAccounts model is set up with…

3. SelectedAccounts Model has a Model Action when Row Updated w/ field ui-checkbox

4. That Model Action starts with a branch thats {{$Model.UI-Only-Model.data.0.AccountId}} == {{Id}} (If the Id matches the record you said you want to remove)

5. If true, remove row in context

6. If false, do nothing

Matt,

Thanks for your help. I think I did everything you said, but if I have a list of 10 accounts and select records 5 & 6. Then deselect 6, the checkbox on the appropriate SelectedAccount record is checked, but the Ui-Only AccountID is that of record 1. It is not the ID of record 6. So record 6 is not removed from the SelectedAccount model.

Matt,

I changed the Model Action Branch formula on the SelectedAccounts model to {{Selected}}==True.  And it worked. Thanks so much!
