Well sometimes you're going to find that Domino has a 65kbyte limit for combobox choices right and if writing the lookup key manually was an alternative, then you'd see that even if you used @Command([ReloadWindow]) the key in the text field would not be passed to the other calculated lookups unless you were using a type of field like a radio button or a combobox with 'Refresh fields upon keyword change'. You could create a radio button with this option and hide it. Then you can create a button with the same Javascript generated for the other radio button on the onClick event. And this will trigger the refresh taking the value of the text field.
