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:
	|	import java.lang.Number;
2.	|	import com.redhat.coolstore.ShoppingCart;
3.	|	
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
