Hi All,  
Can I protect the state of this ui\_template from destruction ?

```

If I click OK:100 or OK:101 the values are restored on browser refresh and all is wonderful.

If I click on BAD:911 I can stop the display of the value but a browser restore returns the last state.

How can I stop my ui state from being corrupted in this fashon ?

P.S. A big thank you goes to [Julian Knight](https://it.knightnet.org.uk/) for the code examples and explanations.
