Description of problem: using brms-coolstore-demo project (https://github.com/eschabell/brms-coolstore-demo/tree/6.0.1) branch 6.0.1

Setup project, start server, AUTHORING -> PROJECT AUTHORING -> GUIDED RULE -> TOTAL SHOPPING CART

Code view tab shows:

4. | rule "Total Shopping Cart"
5. | no-loop true
6. | ruleflow-group "total-rules"
7. | dialect "mvel"
8. | when
9. | $sc : ShoppingCart( )
10. | then
11. | $sc.setCartTotal( 0.0 );
12. | $sc.setCartItemPromoSavings( 0.0 );
13. | update( $sc );
14. | end

Using editor I remove the literal field behind line 12, changing to:

$sc.setCartItemPromoSavings( ($sc.cartItemPromoSavings == 0.0) ? 0.0 : $sc.cartItemPromoSavings * -1 );

Save the file, says successful, but close pop-up warns 'Sure you want to discard unsaved changes?', only choice is yes or cancel. Close rule, reopen and changes not shown.

From command line clone ssh://localhost:8001/coolstore-demo and view source of same guided rule and it shows change:

import java.lang.Number;
import com.redhat.coolstore.ShoppingCart;

rule "Total Shopping Cart"
no-loop true
ruleflow-group "total-rules"
dialect "mvel"
when
$sc : ShoppingCart( )
then
$sc.setCartTotal( 0.0 );
$sc.setCartItemPromoSavings( ($sc.cartItemPromoSavings == 0.0) ? 0.0 : $sc.cartItemPromoSavings * -1 );
update( $sc );
end

Restart of server does not show new changes in UI editor either. No caching on in browser.
