Lex does not reset the Next/Finish button after a bad value entry.

[Nithos]

Lex correctly blocks bad value entries, however after an error and fix of the value to be correct the Next/Finish button does not work. Clicking on it fails, using Tab/Enter on the keyboard correctly progresses the field entry.

Reproduction.

1. Go to the Lex Number example
2. Select any of the types (Age, Height, Weight)
3. Enter a string value to trigger an error (i.e invalid entry will set the input box to red)
4. Correct the value by entering a numeric value
5. Click the 'Finish' button

Expected
Finish should complete the pill entry.

Actual
Finish button does nothing.

NOTE: using the keyboard Tab/Enter works as intended even after error
