Hi all,

I don't know if this is related to the recent update, but I am rebuilding a view with an indirect tag binding. The original works fine:

Binding is indirect on this tag:

```auto
[default]Machine Process/TMs/{1}_TM1/Enabled
param: {view.params.zoneKey}
Bidirectional

```

New build:

```auto
[default]Machine Process/TMs/{1}_TM1/Enabled
param: {view.params.zone} (I changed zoneKey to zone in the new build.)
Bidirectional

```

When I add the parameter and click OK, and reopen, the parameter is empty. The error, before and after clicking OK is: `Error configuration: expression is empty`.

Thoughts? Thanks in advance.

Edit: I even changed the binding parameter to `view.custom.zone`

And it's still empty when I reopen it.

When you change the property make sure you hit enter to confirm the change, otherwise it does not see it.

I've been stymied by that a few times myself 🙂
